A diagram showing the life-history and migration of the Malaria parasite
A diagram showing the life-history and migration of the Malaria parasite, Laverania Malariæ, as discovered by Laveran, Ross, and Grassi. The stages above the dotted line take place in the blood of man. The oblong-pointed parasite is seen entering the blood at n just below No. 1. The circles represent the red blood-discs of man. Schizogony means multiplication by simple division or splitting, and it is seen in Nos. 6, 7, 8, 9, and 10. The stages below the dotted line are passed in the body of the spot-winged gnats of the genus Anopheles. A peculiar crescent or sausage-shaped condition is assumed by the parasite inside the red corpuscle No. VI. These are found to be of two kinds, male and female, Nos. VIIa and VIIb. They are swallowed by the spot-winged gnat when it sucks the blood of an infected man. Here in the gut of the gnat they become spherical; the male spheres produce spermatozoa No. Xa, which fuse with and fertilize the female spheres or egg-cells No. XI. An active worm-like form No. XIII results, which pushes its way partly through the wall of the gnat’s gut, and is then nourished by the gnat’s blood. It swells up, divides internally again and again, and is enclosed in a firm transparent case or cyst, Nos. XIV to XVIII. The cysts are far larger in proportion than is shown in the diagram, and are visible to the naked eye. The final product of the breaking up, which is called sporogony, is a vast number of needle-shaped spores or young (called Exotospores, as opposed to the Enhæmospores, which are formed in the human blood, as seen in Nos. 9 and 10, and serve there to spread the infection among the red corpuscles). The needle-shaped spores formed in the gnat’s body accumulate in its salivary glands, and pass out by the mouth of the gnat when it stabs a new human victim who thus becomes infected, No. XIX.

Bronze Age
The British were able to produce a certain coarse material from the flax which they had but lately learnt to grow, so by now they were not wholly dependent on the skins of animals for clothing.

Celtic implements
Their bronze and iron ornaments and utensils were very artistic, curves and scrolls and intertwined work being the chief characteristics of early Celtic Art. Enamelling in red colours was much used on metal work, and studs of coral and pearls, or some bright pebble, were worked into their breastplates, shields, and helmets.

Celtic women
A torque of gold was worn as a necklace, and bracelets of bronze or gold were worn on the arms. The hair, parted in the middle and flowing over the shoulders, was bound by a circlet of gold and twisted wire. Sometimes a sort of super-tunic, without sleeves and reaching to just below the knees, with a check border, would be worn over the long gwn. It was confined at the waist with a belt, fastened and ornamented with bosses of bronze or gold. Women of less exalted `rank` wore the same style of dress, but of coarser cloth and less elaborately decorated.

Drawing of the skull and lower jaw of the Meritherium, discovered by Dr. Andrews in the Upper Eocene of the Fayum Desert.
Drawing of the skull and lower jaw of the Meritherium, discovered by Dr. Andrews in the Upper Eocene of the Fayum Desert. The shape of the skull and proportions of face and jaw are like those of an ordinary hoofed mammal such as the pig; but the cheek-teeth are similar to those of the Mastodon, and whilst the full complement of teeth is present in the front of the upper jaw, we can distinguish the big tusk-like incisor which alone survives on each side in Palæomastodon, Mastodon, and the elephants, as the great pair of tusks.

The earliest discovered Trypanosome, described by Gruby in 1843
The earliest discovered Trypanosome, described by Gruby in 1843 as “Trypanosoma sanguinis” and found by him in the blood of the common esculent Frog. It was not noticed again until it was re-discovered by Lankester in 1871, who published the figure of it in the Quarterly Journal of Microscopical Science in that year.
The Freshwater Jelly-fish of Lake Tanganyika
The Freshwater Jelly-fish of Lake Tanganyika (Limnocnida Tanganyicae), Since its discovery in Tanganyika it has been found also in the Lake Victoria Nyanza and in pools in the Upper Niger basin.
The Freshwater Jelly-fish of Regent’s Park (Limnocodium Sowerbii)
The Freshwater Jelly-fish of Regent’s Park (Limnocodium Sowerbii) It was discovered in the tropical lily tank of the Botanical Gardens in June, 1880, and swarmed in great numbers year after year—then suddenly disappeared. It has since been found in similar tanks in Sheffield, Lyons, and Munich. Only male specimens were discovered, and the native home of the wonderful visitor is still unknown.

The Number of the Chromosomes
(a) Cell of the asexual generation of the cryptogam Pellia epiphylla: the nucleus is about to divide, a polar ray-formation is present at each end of the spindle-shaped nucleus, the chromosomes have divided into two horizontal groups each of sixteen pieces: sixteen is the number of the chromosomes of the ordinary tissue cells of Pellia. (b) Cell of the sexual generation of the same plant (Pellia) in the same phase of division, but with the reduced number of chromosomes—namely, eight in each half of the dividing nucleus. The completed cells of the sexual generation have only eight chromosomes. (c) Somatic or tissue cell of Salamander showing twenty-four ∨-shaped chromosomes, each of which is becoming longitudinally split as a preliminary to division. (d) Sperm-mother-cell from testis of Salamander, showing the reduced number of chromosomes of the sexual cells—namely, twelve; each is split longitudinally. (From original drawings by Prof. Farmer and Mr. Moore.)

The unicellular parasite Benedenia, from the gut of the common Poulp or Octopus. 1 is the normal male individual; 2 and 3 show stages in the production of spermatozoa on its surface by budding; 4, 5 and 6 show a female parasite with spermatozoa approaching it.
The young of the common Eel and its metamorphosis
Drawings by Professor Grassi, of Rome, of the young of the common Eel and its metamorphosis. All of the natural size. The uppermost figure represents a transparent glass-like creature—which was known as a rare “find” to marine naturalists, and received the name Leptocephalus. Really it lives in vast numbers in great depths of the sea—five hundred fathoms and more. It is hatched here from the eggs of the common Eel which descends from the ponds, lakes, and rivers of Europe in order to breed in these great depths. The gradual change of the Leptocephalus into a young Eel or “Elver” is shown, and was discovered by Grassi. The young Eels leave the great depth of the ocean and ascend the rivers in immense shoals of many hundred thousand individuals, and wriggle their way up banks and rocks into the small streams and pools of the continent.
Torques
Round the neck he might have an ornament called a " torque," composed of twisted gold wire, and bracelets of the same on the arms and wrists. These seem to have been worn only by chiefs, and were much prized by their Roman conquerors.
Trypanosoma Ziemanni, from the blood of the little owl
Trypanosoma Ziemanni, from the blood of the little owl. The stages shown in Figs. 52–54 are passed inside the gnat. The spiral and pear-shaped bodies of Fig. 54 pass from the gnat’s proboscis into the blood of the little owl, and grow there into the large forms here figured. A, B, and C are females, destined to be fertilized by spermatozoa when swallowed by a gnat. D and E are male Trypanosomes, which will give rise each to eight fertilizing individuals or spermatozoa as shown in Fig. 56—when swallowed by a gnat.
