- An Eight-Armed Cuttlefish or Octopus Attacking a Small Crab
These molluscs are particularly fond of crustaceans, which they crunch with their parrot's beak-like jaws. Their salivary juice has a paralysing effect on their prey. To one side, below the eye, may be seen the funnel through which water is very forcibly ejected in the process of locomotion. - SM
SM or MS - Surinam Toad (Pipa Americana) with Young Ones Hatching out of Little Pockets on her Back
In the case of the thoroughly aquatic Surinam Toad (Pipa), the male helps to press the eggs, perhaps a hundred in number, on to the back of the female, where each sinks into a pocket of skin with a little lid. By and by fully formed young toads jump out of the pockets. - MS
SM or MS - Diagram of amœba
The amœba is one of the simplest of all animals, and gives us a hint of the original ancestors. It looks like a tiny irregular speck of greyish jelly, about 1/100th of an inch in diameter. It is commonly found gliding on the mud or weeds in ponds, where it engulfs its microscopic food by means of out-flowing lobes (PS). The food vacuole (FV) contains ingested food. From the contractile vacuole (CV) the waste matter is discharged. N is the nucleus, GR, granules. - The Cause of Tides
The tides of the sea are due to the pull of the moon, and, in lesser degree, of the sun. The whole earth is pulled by the moon, but the loose and mobile water is more free to obey this pull than is the solid earth, although small tides are also caused in the earth's solid crust. The effect which the tides have on slowing down the rotation of the earth is explained in the text. - Volvox
The Volvox is found in some canals and the like. It is one of the first animals to suggest the beginning of a body. It is a colony of a thousand or even ten thousand cells, but they are all cells of one kind. In multicellular animals the cells are of different kinds with different functions. Each of the ordinary cells (marked 5) has two lashes or flagella. Daughter colonies inside the Parent colony are being formed at 3, 4, and 2. The development of germ-cells is shown at 1. - Proterospongia
One of the simplest multicellular animals, illustrating the beginning of a body. There is a setting apart of egg-cells and sperm-cells, distinct from body-cells; the collared lashed cells on the margin are different in kind from those farther in. Thus, as in indubitable multicellular animals, division of labour has begun - New York - Burning of the Provost Marshal's office
- The comparative sizes of the sun and the planets
(Drawn approximately to scale) On this scale the Sun would be 17½ inches in diameter; it is far greater than all the planets put together. Jupiter, in turn, is greater than all the other planets put together. - Chicago - The fight at Turner Hall , arrival of U.S. Artillery

- Early Life-History of the Salmon
1. The fertilised egg, shed in the gravelly bed of the river. 2. The embryo within the egg, just before hatching. The embryo has been constricted off from the yolk-laden portion of the egg. 3. The newly hatched salmon, or alevin, encumbered with its legacy of yolk (Y.S.). 4 and 5. The larval salmon, still being nourished from the yolk-sac (Y.S.), which is diminishing in size as the fish grows larger. 6. The salmon fry about six weeks old, with the yolk fully absorbed, so that the young fish has now to feed for itself. The fry become parr, which go to the sea as smolts, and return as grilse. In all cases the small figures to the right indicate the natural size. - New York - Rioters soaping the tracks at Hornellsville

- The Flipper of a Whale compared to the hand of man
In the bones and in their arrangement there is a close resemblance in the two cases, yet the outcome is very different. The multiplication of finger joints in the whale is a striking feature. - The Planets, Showing their Relative Distances and Dimensions
(Drawn approximately to scale) The isolation of the Solar System is very great. On the above scale the nearest star (at a distance of 25 trillions of miles) would be over one half mile away. The hours, days, and years are the measures of time as we use them; that is: Jupiter's "Day" (one rotation of the planet) is made in ten of our hours; Mercury's "Year" (one revolution of the planet around the Sun) is eighty-eight of our days. Mercury's "Day" and "Year" are the same. This planet turns always the same side to the Sun. - Reading - Burning of the Lebanon Valley Bridge

- Pariasaurus - An Extinct Vegetarian Triassic Reptile
Total length about 9 feet. (Remains found in Cape Colony, South Africa.) - Triceratops - A Huge Extinct Reptile
(From remains found in Cretaceous strata of Wyoming, U.S.A.) This Dinosaur, about the size of a large rhinoceros, had a huge three-horned skull with a remarkable bony collar over the neck. But, as in many other cases, its brain was so small that it could have passed down the spinal canal in which the spinal cord lies. Perhaps this partly accounts for the extinction of giant reptiles. - Genealogical tree of animals

This pictorial diagram illustrates the principal of Spectrum Analysis, showing how sunlight is decomposed into its primary colours. What we call white light is composed of seven different colours. The diagram is relieved of all detail which would unduly obscure the simple process by which a ray of light is broken up by a prism into different wave-lengths. The spectrum rays have been greatly magnified. - Comparative size of molecules
An atom is the smallest particle of a chemical element. Two or more atoms come together to form a molecule: thus molecules form the mass of matter. A molecule of water is made up of two atoms of hydrogen and one atom of oxygen. Molecules of different substances, therefore, are of different sizes according to the number and kind of the particular atoms of which they are composed. A starch molecule contains no less than 25,000 atoms. Molecules, of course, are invisible. The above diagram illustrates the comparative sizes of molecules. - Wing of a Bird, Showing the Arrangement of the Feathers
The longest feathers or primaries (PR) are borne by the two fingers (2 and 3), and their palm-bones (CMC); the second longest or secondaries are borne by the ulna bone (U) of the fore-arm; there is a separate tuft (AS) on the thumb (TH). - A Map of the Chief Plains and Craters of the Moon

Players Navy Cut - Ships the British, and the German, navy might have had
Ships the British, and the German, navy might have had! Designs by the Kaiser and other naval theorists. The first illustration on this page is a design for a battle-ship made by the Kaiser in 1893, to replace the old "Preussen," then out of date. The vessel was to carry four large barbettes and a huge umbrella-like fighting-top. Illustration No. 2 is an Immersible Ironclad, designed by a French engineer named Le Grand, in 1862. In action the vessel was to be partly submerged, so that only her three turrets and the top of the armoured glacis would be visible. No. 3 is Admiral Elliott's "Ram," of 1884. The ship was to carry a "crinoline" of stanchions along her water-line, practically a fixed torpedo-net. No. 4 is Thomas Cornish's Invulnerable Ironclad, of 1885. She was to have two separate parallel hulls under water; above she was of turtle-back shape.
