- Choice of fabric
Here a small all-over pattern minimizes size, the plaits and tassels lengthen, the necklace adds a slenderizing touch. The appearance as a whole is graceful and youthful. - Two looks - same pattern
Would you believe that the pattern of these two dresses is exactly the same? This illustrates how you can vary a dress once you find the foundation lines that are becoming to you. One pattern can suffice for both a tailored and an afternoon dress, as you see both effects are pleasing in their slenderness. - Hats 1
These two examples show how even a hat with drooping brim, if not too wide, can be worn by the stout person if trimming is adeptly used to direct the vision upward and lend an illusion of height. - Hats 2
Here trimming is used on two entirely different types of hats to give in each case added height to the figure and help in attaining a slenderizing appearance. Left—Hats with medium brims and high trimming are often becoming, especially if wide enough to avoid the pyramid effect. Right—High built trimming and delicate veils are advantageous where a double chin is the handicap. - Optical Illusion in dress
Note the diagonal line in the small diagram of the figure below. It is actually straight, but the vertical lines which break it give it a “going-down-steps” appearance. This principle is used in the dress below—the two vertical panels of trimming break the line of the tunic and give the whole figure a more slender appearance than in the figure above. - A Ganglion of a Leech
Pear-shaped cells are set round a felt-work of nerve-fibrils (neuropil). A neuro-sensory cell is shown with one fibre directed peripherally, branching on the surface; and one directed centrally, ramifying in the neuropil. Several very slender fibrils from the neuropil pass up the stalk of each ganglion-cell. They join a network near its surface. This net is connected by radiating fibrils with a coarser net which surrounds the nucleus. From the central net a relatively stout fibril passes to muscle-fibres. - The Growth and Migration of Granules of the Cerebellum
Half a dozen nuclei of as yet undeveloped granules are seen lying beneath the pia mater. From this level to the bottom of the drawing granules are shown in successive stages of growth. These developing granules, selected from various preparations of the cortex of the cerebellum, were drawn from nature. - The Body of a Motor Neurone
In its centre is a large clear spherical nucleus, with a nucleolus. The body-substance is prolonged into five dendrites and an axon. Neuro-fibrillæ are seen in dendrites and axon. They traverse the body of the cell in all directions, in little bundles which are separated by angular granules of stainable substance (tigroids). - The Surface of the Left Cerebral Hemisphere, Cerebellum,and Medulla Oblongata.
Sensory areas are enclosed by broken lines; certain centres in the association-zones are marked by dots. The sensory area of smell is on the inner aspect of the brain; so also is the area of vision which borders the calcarine and retrocalcarine fissures, and only rarely extends on to the external surface, as shown in the diagram. The sensory area of hearing is largely hidden within the fossa of Sylvius, the opening into which is indicated by the dark line above it. The kinæsthetic-sensory areas for the various muscles of the body occupy the territory between the dotted line in front and the bottom of the fissure of Rolando behind. They do not extend on to the posterior wall of this fissure. It is impossible at present to define the boundaries of any of the centres in the association-zones. - Highly Magnified Section through the Wall of a Circumvallate Papilla of the Tongue, showing Two Taste-Bulbs.
These sense-organs are groups of elongated epithelial cells, set vertically to the surface. Their cells are of two kinds—the one fusiform, slender, bearing each a bristle-like process which projects through a minute pore left between the superficial cells of the general epithelium; the other thicker and wedge-shaped. Nerve-fibres are connected with the fusiform cells. - Horizontal Section through the Right Eye
The slight depression in the retina in the axis of the globe is the fovea centralis, or yellow spot; the optic nerve pierces the ball to its inner or nasal side. The lens, with its suspensory ligament, separates the aqueous from the vitreous humour. On the front of the lens rests the iris, covered on its posterior surface with black pigment. On either side of the lens is seen a ciliary process, with the circular fibres of the ciliary muscle cut transversely, and its radiating fibres disposed as a fan. - The Retina in Vertical Section
A, after Exposure to Bright Light; B, After Resting in the Dark. The arrow shows the direction in which light traverses the retina. C, Retinal epithelium, with its pigmented fringe. 1, Layer of rods and cones, separated by the external limiting membrane from 2, the layer of the nuclei of the rods and cones. 3, The ganglion-cells of the retina, which are homologous with the cells of the afferent root of a spinal nerve. Their peripheral axons ramify beneath the sensory epithelium (rods and cones and their nucleus-bearing segments), their central axons in 4, the inner molecular layer. D, Collecting cells on the front of the retina; a a a, their axons which conduct impulses to the brain; b, an efferent fibre from the brain. - The Formation of an Image by the Refracting Media of the Eye
x, The common centre of curvature (nodal point of the several media). Rays which pass through this point are not deflected. y, The principal focus of the system. All rays which are parallel to the optic axis converge to this point. The image of the point A is formed at a, the spot at which a ray parallel with the optic axis meets an unbent ray—the image of B at b. - The External, Middle, and Internal Ear of the Left Side
From right to left, the figure shows the concha and lobule of the ear in profile; the external meatus (abbreviated); the drum, divided vertically, its posterior half visible; the hammer-bone, with the tip of its long arm attached to the drum, an arrow indicating the point of attachment and line of action of the tensor tympani muscle; the anvil attached by a ligament to the bony wall of the middle ear; the stirrup, with its foot-plate almost filling the oval window; the labyrinth, with the three semicircular canals above, and the scala vestibuli below. The curled black line shows the situation of the scala media, or ductus cochleæ (which contains the organ of Corti). Pulsations of sound which move the membrana tympani are transmitted by the three bones to the oval window. They shake the perilymph, producing waves which travel along the scala vestibuli to the apex of the cochlea, whence they return by the scala tympani to the round window (if they do not take a shorter course through the ductus cochleæ). The Eustachian tube opens out of the lower part of the middle ear. - Organ of Corti
The spiral lamina, on the left of the drawing, gives attachment to the membrane of Corti, which stretches to the opposite wall. Below the membrane is a bloodvessel which runs its whole length beneath the tunnel of Corti. The tunnel is formed by pillars—the inner on the left, the outer on the right—which meet above it. On the left of the inner pillar is a hair-cell; to the left of this a nerve-cell with two nuclei. To the right of the outer pillar is a space; to the right of this four hair-cells alternating with four supporting cells, which hold up the reticulated membrane through apertures in which the tufts of hairs project. Three nerve-fibres are seen in the spiral lamina; they cross the tunnel to ramify between the rows of outer hair-cells. The lamina tectoria rests upon the tufts of hairs. - Sense-Organs susceptible to Pressure
All are formed on essentially the same plan; a fibrous capsule invests a group of epithelial cells amongst which a nerve ramifies. The simplest form is known as a Grandry’s corpuscle-a nerve ending in one or two plates between two or three epithelial cells. These organs are found in great numbers in the bills of aquatic birds. If a duck is watched whilst it is gobbling mud at the margin of a pond, it will be seen to have a remarkable capacity for discriminating between the shells of small snails, which it can crush, and stones, which it needs to drop from its bill. Its bill is also provided with small Pacinian corpuscles. - The Anterior Half of the Larynx seen from Behind
The drawing shows the folds of mucous membrane, the vocal cords, which stretch from the tips of the arytenoid cartilages to the recess behind the median portion of the thyroid cartilage. To the outer side of each vocal cord is seen the thyro-arytenoid muscle (cut across), consisting of a broad outer portion, chiefly concerned in closing the glottis during the act of swallowing, and a smaller internal portion, which regulates the length and the thickness of the segment of the cord allowed to vibrate. - Diagram showing the Relative Positions of the Organs of the Chest and Abdomen.
The ribs from the first to the tenth have been cut across in the lateral line. The eleventh and twelfth ribs do not reach sufficiently far forwards to be cut. With the exception of a short segment near its junction with the ascending colon, the small intestine has been removed. The trachea is seen to divide into bronchi beneath the arch of the aorta. The right lung has three, the left two lobes. The kidneys are situated behind all the other viscera. On their upper ends rest the two suprarenal capsules. The lower edge of the right lobe of the liver follows closely the line of the ribs and costal cartilages. Below the left lobe of the liver the stomach comes to the anterior abdominal wall. The transverse colon (large intestine) comes to the anterior wall below the stomach. Below the latter the wall is in contact chiefly with coils of small intestine. The vermiform appendix rests on the posterior wall. Spleen and pancreas are not shown in the diagram. - Red Blood-Corpuscles presenting, some the Surfaces, others the Edges, of their Discs, together with Single Representatives of Four Types of Leucocyte.
A, the most common type, highly amœboid and phagocytic. Its protoplasm is finely granular, its nucleus multipartite. B, a leucocyte closely similar to the last, but larger, and containing an undivided nucleus. It is shown with a cluster of particles of soot in its body-substance. C, a young leucocyte, or “lymphocyte.” D, a coarsely granular leucocyte. Its granules stain brightly with acid dyes—e.g., eosin or acid fuchsin. - A Minute Portion of the Pulp of the Spleen
A Minute Portion of the Pulp of the Spleen,very highly magnified. Stellate connective-tissue cells form spaces containing red blood-corpuscles and leucocytes. In the centre of the diagram is shown the mode of origin of a venule. It contains two phagocytes—the upper with a nucleus, two blood-corpuscles just ingested, and one partially digested in its body-substance; the lower with two blood-corpuscles. - Digestive system in humans
The stomach has been cut across a short distance from the pyloric valve, and removed, to show the viscera which lie behind it. The descending aorta and the vena cava rest upon the vertebral column. They are crossed by the pancreas and the transverse portion of the duodenum. The head of the pancreas is enclosed by the curvatures of the duodenum. The ducts of the liver and pancreas are seen entering the descending duodenum side by side. - Diagram of a Lobule of the Liver
Diagram of a Lobule of the Liver divided vertically through its Axis. In its centre is a space, the intralobular vein, through which the blood falls into a branch of the hepatic vein, on its way to the heart. An interlobular branch of the portal vein, which brings the blood from the digestive organs, pours it by many smaller vessels over the surface of the lobule. It filters into the lobule through innumerable pseudo-capillary vessels, or spaces, between the radiating columns of liver-cells. Arterial blood is brought to the lobule by a twig of the hepatic artery. Bile is drained away from it by an affluent of the hepatic duct. In the lower part of the diagram seven liver-cells are shown, forming a divided column, magnified about 300 diameters. The cells are loaded with glycogen, and contain minute globules of fat. Red blood-corpuscles and two leucocytes are seen between the columns of liver-cells. One of the leucocytes has ingested two blood-corpuscles. - The Diaphragm and Organs in Contact with it
The Diaphragm and Organs in Contact with it—A, in Expiration; B, at the End of a Deep Inspiration. Transverse Vertical Sections in the Line of the Armpit. A, At the end of an ordinary expiration the lung does not extend below the upper border of the eighth rib. From this level to the middle or lower border of the tenth rib the two layers of the pleura covering respectively the inner wall of the chest and the upper surface of the diaphragm are in contact. B, When the lung is distended with air it occupies the whole of the pleural cavity. - The Heart cut in the Plane of its Long Axis, and the Vessels which open into and out of it
Chordæ tendineæ attach the margins of the auriculo-ventricular valves to musculi papillares which project from the inner aspect of each ventricle. - A Section approximately at Right Angles to the Long Axis of the Heart
A Section approximately at Right Angles to the Long Axis of the Heart, exposing the Four Valves which lie very nearly in the Same Plane. The semilunar valve which guards the aperture of the pulmonary artery is the nearest to the breast-bone. - Manometer for measuring Blood-Pressure
A U-tube contains mercury, on which floats a rod supporting a scratching point, which makes a “tracing” on blackened paper wrapped round a revolving drum. Between the manometer and the cannula which is introduced into the central end of a cut artery is a three-way cock, which leads to a pressure-bottle containing a half saturated solution of sodic sulphate. This solution prevents blood from clotting. Before it is connected with the artery the apparatus is filled from the pressure-bottle. The cock is then turned into the second position, and the bottle raised until the mercury in the manometer stands at a level somewhat higher than that which it may be expected to attain under the influence of blood-pressure. The cannula being then inserted into an artery, the cock is turned into the third position, which places the manometer in connection with the blood, and excludes the pressure-bottle. As the mercury is a little higher than blood-pressure, some of the sodic sulphate solution enters the artery, but no blood enters the cannula. The scratching point, rising and falling with every variation in blood-pressure, makes a record on the soot-blackened paper, which is subsequently removed from the drum, and varnished. - Sphygmograph
A, An ivory button which is pressed on the skin over the radial artery by a metal spring. B, A continuous screw which works against the cogwheel C. By rotating B, the lever D is raised to a position in which its point scratches the travelling-plate E (covered with blackened paper). F, A box containing clockwork which moves E. G, A screw by means of which the pressure of the spring is adjusted to the force of the pulse. - Biceps Muscle in Action
The power of muscle varies as its cross-section. For human muscles the maximum lift amounts to from 7 to 10 kilogrammes for each square centimetre. This is a large figure, but it must be remembered that, owing to the arrangement of the bones as levers, most muscles act at a great mechanical disadvantage. The greater the difference in distance from the fulcrum between the point of application of the force and the point of incidence of the weight, when the force acts nearer to the fulcrum than the weight, the greater is the mechanical disadvantage. The greater also is the rapidity with which the weight is lifted. What is lost in strength is gained in swiftness - Section of First-rate Man-of-War
I will now give you a sectional division of a first-rate line-of-battle ship. Such a ship, carrying 120 or more guns, has four decks on which her guns are placed. The highest is open to the air, and is called the UPPER DECK At the after part, extending a little way beyond the mizen-mast, there is a raised platform, called the POOP. It has no guns on it. On the main deck is the steering-wheel, with the binnacle in front of it. The after part of this deck between the poop and the main-mast is called the quarter-deck, and is the place where the officers especially walk. The part under the poop is divided into cabins, appropriated to the use of the captain. Here, also, is a clerk's office and a pantry. Between the main and fore-mast the large boats are stowed, and on either side are the gangways at which sentries are stationed. The next deck under this is called the MAIN DECK. In the after part is the admiral's cabin. Immediately under the boats is a pen for the officers' live-stock ; and just abaft the fore-mast is the galley, or kitchen. The third deck from the upper is called the MIDDLE DECK. The after part is fitted up for the lieutenants, chaplain, surgeon, paymaster, marine officers, &c., and called the WARD-ROOM. In the fore part of the deck is placed the sick-bay, a compartment fitted up as a hospital ; about the centre of this deck is one of the capstans. The fourth from the upper is called the LOWER or GUN DECK. In the after part is the GUN-ROOM, where the midshipmen, and other junior officers, mess. The tiller of the rudder works through the gun-room just above their heads. A second capstan is placed on this deck ; and forward are the riding-bitts for securing the cables. It is the lowest deck on which guns are carried. The ORLOP DECK is the fifth deck from the upper. It has no guns or ports, though lighted up by bull's eyes or scuttles. In the after part is the purser's issue-room ; next to it is the after cockpit, where the midshipmen and other junior officers sleep in hammocks. Before it again will be found the sail-room, where the sails are kept, and the cable-tiers, where the cables are stowed. Before it again, just abaft the fore-mast, is the fore cockpit, and the warrant officers' cabins, while right in the head of the ship are the carpenter's and boatswain's stores. Low as we have got, we have still further to go down to the HOLD, which, if it may be so called, is the sixth deck from the highest. It is often divided into two decks for the greater convenience of stowage. Here are the FORE AND AFTER MAGAZINES, WATER TANKS, WINE AND SPIRIT ROOM, CHAIN CABLE LOCKERS, SHOT LOCKERS, BREAD ROOM, SHELL ROOM, GUNNER'S STORE ROOM, DRY PROVISION, and BEEF AND PORK IN CASKS. Since the introduction of auxiliary steam-power into ships of war, a large portion of the hold is devoted to the steam-engine and boilers, coal bunkers, and the shaft of the screw, while the funnel runs up through all the decks ; but it is wonderful, comparatively, how little space these are allowed to occupy, considering the great aid the steam-engine affords to the movements of the ship. - The 'Minotaur'
Launched in 1863 Among the numerous huge monsters constituting the iron-clad fleet of England, the Minotaur, is one of the most gigantic and formidable; and the sister ships, the Agincourt and Northumberland, all of precisely the same tonnage, power, rig, and equipment, are the largest and most powerful ships in the navy. The Minotaur was built at Blackwall, by the Thames Ship Building company and the engines were constructed by Messrs. Penn, of Deptford. She is 6,621 ton's measurement, and propelled by screw engins of 1,350 horsepower, with a speed of 15 knots an hour. She is 400 feet in length by 59 in width, and carries in all thirty-four of the heaviest guns used afloat. Among these which form her chief batter on the main deck are four 300-pounder Armstrongs. - Baseball pitches
Left to right - The In-Curve, the out-curve, the drop and the out-drop The pitcher is the most important member of a ball team. Most of the work falls to him, and a good pitcher, even with a comparatively weak team behind him, can sometimes win games where a good team with a weak pitcher would lose. A good pitcher must first of all have a cool head and keep his nerve even under the most trying circumstances. He must also have good control of the ball and be able to pitch it where he wants it to go. After that he must have a knowledge of curves and know how by causing the ball to spin in a certain way to cause it to change its course and thus to deceive the batsman. The art of curving a ball was discovered in 1867. Before that time all that a pitcher needed was a straight, swift delivery. The three general classes of curved balls used to-day are the out-curve, the in-curve, and the drop. There are also other modifications called "the fade away," "the spitball," and others. Curve pitching will only come with the hardest kind of practice. - The Wilderness Traveller
Forest travellers are always on the lookout for peculiar landmarks that they will recognize if they see them again. Oddly shaped trees, rocks, or stumps, the direction of watercourses and trails, the position of the sun, all these things will help us to find our way out of the woods when a less observing traveller who simply tries to remember the direction he has travelled may become terrified. - The right way to mount—facing toward his tail
In mounting, stand on the left side and place the left foot in the stirrup. Swing the right leg over the horse and find the right stirrup with the toe just as quickly as possible. Do not jerk a restless horse or otherwise betray your excitement if he starts. Let him see by your calmness that he too should be calm. - The lineup
The position of the men on a team is generally as the diagram shows but for various plays other formations are used, provided that they do not violate the rules, which specify just how many men must be in the lineup and how many are permitted behind the line. - The hockey player's costume

An Indian tepee - An excellent device for catching minnows
The simplest way to catch minnows is with a drop net. Take an iron ring or hoop such as children use and sew to it a bag of cotton mosquito netting, half as deep as the diameter of the ring. Sew a weight in the bottom of the net to make it sink readily and fasten it to a pole. When we reach the place which the minnows frequent, such as the cove of a lake, we must proceed very cautiously, lowering the net into the water and then baiting it with bits of bread or meat, a very little at a time, until we see a school of bait darting here and there over the net. We must then give a quick lift without any hesitation and try to catch as many as possible from escaping over the sides. The minnow bucket should be close at hand to transfer them to and care must be used not to injure them or allow them to scale themselves in their efforts to escape. - Addressing
Addressing the golf ball before starting the swing - A type of camp fire that will burn all night
A type of camp fire that will burn all night To make a fire that will burn in front of the tent all night, first drive two green stakes into the ground at a slant and about five feet apart. Then lay two big logs one on each side of a stake to serve as andirons. Build a fire between these logs and pile up a row of logs above the fire and leaning against the stakes. You may have to brace the stakes with two others which should have a forked end. When the lower log burns out the next one will drop down in its place and unless you have soft, poor wood the fire should burn for ten hours. With this kind of a fire and with a leanto, it is possible to keep warm in the woods, on the coldest, night in winter. - A self-sustaining or balanced aquarium
three children looking at an aquarium Any transparent vessel capable of holding water, even a Mason jar will make an aquarium from which a great deal of pleasure may be derived. The old way of maintaining aquaria in good condition required a great deal of care and attention. The water had to be changed at least once a day if running water was not available, and altogether they were so much trouble that as a rule owners soon tired of them. Modern aquaria are totally different. By a proper combination of fish and growing plants we can almost duplicate the conditions of nature and strike a balance so that the water need never be changed except when it becomes foul or to clean the glass. - A reflector camp oven
There are several kinds of ovens used for baking bread and roasting meat in outdoor life. The simplest way is to prop a frying pan up in front of the fire. This is not the best way but you will have to do it if you are travelling light. A reflector, when made of sheet iron or aluminum is the best camp oven. Tin is not so satisfactory because it will not reflect the heat equally. Both the top and bottom of the reflector oven are on a slope and midway between is a steel baking pan held in place by grooves. This oven can be moved about at will to regulate the amount of heat and furthermore it can be used in front of a blazing fire without waiting for a bed of coals. Such a rig can easily be made by any tinsmith. A very convenient folding reflector oven can be bought in aluminum for three or four dollars. When not used for baking, it makes an excellent dishpan. - A landing net should be a part of every fisherman's outfit
A landing net should be a part of every fishing outfit. More fish are lost just as they are about to be lifted from the water than at any other time. A gaff is used for this same purpose with fish too large to go into a landing net. A gaff is a large hook without a barb fastened into a short pole. If you have no net or gaff and have succeeded in bringing a large fish up alongside the boat, try to reach under him and get a firm grip in his gills before you lift him on board. If it is a pickerel, look out for his needle-like teeth. - A home-made rabbit house
A rabbit hutch or coop is easily built from old packing boxes. One third of the coop should be darkened and made into a nest, with an entrance door outside and the rest simply covered with a wire front, also with a door for cleaning and feeding. The hutch should stand on legs above ground as rabbits do not thrive well in dampness. They will, however, live out all winter in a dry place. A box four feet long and two feet wide will hold a pair of rabbits nicely. Rabbits will become very tame and may often be allowed full liberty about the place if there are no dogs to molest them. The drawing shows a standard type of rabbit hutch. A boy who is handy with tools can easily build one. We can always dispose of the increase in our rabbit family to friends or to dealers. - A home-made chicken coop built on the 'scratching-shed' plan
A chicken coop for grown fowls can be of almost any shape, size, or material, providing that we do not crowd it to more than its proper capacity. The important thing is to have a coop that is dry, easily cleaned and with good ventilation, but without cracks to admit draughts. A roost made of two by four timbers set on edge with the sharp corners rounded off is better than a round perch. No matter how many roosts we provide, our chickens will always fight and quarrel to occupy the top one. Under the roost build a movable board or shelf which may easily be taken out and cleaned. Place the nest boxes under this board, close to the ground. One nest for four hens is a fair allowance. Hens prefer to nest in a dark place if possible. A modern, up-to-date coop should have a warm, windproof sleeping room and an outside scratching shed. A sleeping room should be provided with a window on the south side and reaching nearly to the floor.
