Venice, 1496, showing the ventricles of the brain - Various species of Trypanosoma from the blood of mammals, birds, and reptiles
Various species of Trypanosoma from the blood of mammals, birds, and reptiles. A. T. Lewisii, from the blood of rats; B. T. Brucei, the parasite of the Nagana or Tsetze-fly disease, found in the blood of horses, cattle, and big game; C. T. gambiense, the parasite causing Sleeping Sickness in man; D. T. equinum, which causes the mal de caderas in South American horse ranches; E. T. noctuæ, from the blood of the little owl, Athene noctua; F. T. avium, found in the blood of many birds; G. a species found in the blood of Indian pigeons; H. T. ziemanni, a second species from the blood of the little owl; J. T. damoniæ, from the blood of a tortoise; c.g., granules; v., vacuole; l.s., fold of the crest or undulating membrane. - Upper Side of Epeira Vulgaris
The head is not separated from the rest of the body, as in insects, but forms, with the thorax, one piece. On the front of the head are eight eyes, Q, which are differently arranged in different spiders. On the abdomen are several pairs of dark smooth spots, which mark the ends of muscles extending downward through the abdomen. The markings of this spider are very complicated. The spot on the middle of the front of the abdomen is a very common one, and, in some spiders, extends the whole length of the body. The waved lines on each side are also common, and, in long-bodied spiders, often form two bright-colored stripes, or rows of spots, running nearly straight the whole length of the abdomen. - Upland Plover
Bartramia longicauda The Upland Plover is a confusing bird. Ornithologists still are arguing about what he should be called—a sandpiper or a plover. He formerly was known as a Bartramian Sandpiper. Now the trend seems to indicate that Upland Sandpiper is a name which fits his habits better than Upland Plover. Altho he has legs long enough for wading, he uses them for traveling thru grasses, not water. When alighting, he holds his wings up momentarily before folding them; in fact most of his actions seem more like a plover. Whatever you call him, he still will be found on prairies and grasslands; marshes and mud flats have no appeal to this bird. The Upland Plover is slightly larger than a Killdeer and is buffy brown in color. His long neck, small head with rather short beak, long tail, hovering flight, but most of all his prolonged call, make identification easy. His long-drawn, mournful whistle seems to blend with breezes which blow above the prairies, and once heard, is not easily forgotten. - Unusual Long Haired Cat

- Two-humped Camel
Two-humped Camel ( Camelus bactrianus ) The Two-humped Camel is bred in all the steppe countries of Central Asia, and is mainly used for the transportation of goods between China and the south of Siberia or Touran. In Bukhara and Turkenia it is gradually being replaced by the Dromedary, which takes its full place where the steppe takes on the characteristics of a desert. - Two Species of Caprellidæ

In the Serpulacees ( Serpulacea ), the gills are located entirely at the front end of the body; the cilia that coat her cause a current to flow into the water, which supplies food to the mouth opening immediately below it. The head segment is not separated from the mouth segment, as is the case with most other Ringworms, but has grown together with it. - Tutored Bear.—XIV. Century
One great part of the joculator's profession was the teaching of bears, apes, horses, dogs, and other animals, to imitate the actions of men, to tumble, to dance, and to perform a variety of tricks, contrary to their nature; and sometimes he learned himself to counterfeit the gestures and articulations of the brutes. - Tutored Bear.—XIV.

Turtle - Turkey Vulture
Turkey Vulture Vultures play an unusual part in nature’s drama. They, along with Sexton Beetles, other insects and animals, form the sanitary unit. When we consider the heavy toll of wildlife along our highways, we can appreciate the usefulness of such a unit. Lacking talons, vultures are not equipped to catch their prey, but feed on whatever nature provides. This vulture is almost eagle size, with a wingspread of 70 inches and can be identified by his long tail, small head, 2-toned wings, and habit of soaring, the wings forming a dihedral or open V-shape. On close inspection, you will find the head bare and a reddish color. The young have blackish heads which is one of the marks of the Black Vulture, but the latter is smaller with a square tail and shows white spots under the wing when flying. This is a southern cousin. - Tufted Titmouse
Tufted Titmouse This sparrow-size cousin of the chickadee has a tuft of feathers which gives him a striking appearance. The tuft, nape, back, wings and tail are slate gray, while the cheek, throat, breast and belly are white with a pinkish-brown patch just below the wing. Habits are similar to chickadees and he often can be found feeding in loose flocks with these and other small birds such as Downy Woodpeckers, nuthatches and Brown Creepers. Together they form a useful team for what one species misses by his method of feeding, one of the others will find by a slightly different method. They nest in holes in trees or even a bird box to their liking. They are noisy birds and their song is much louder and clearer than you would expect to hear from such small singers. The song consists of a series of whistled notes which sound like “pet-er” or “pet-o,” the first note usually slightly higher. Other notes remind you of a Carolina Wren or a Kentucky Warbler but the phrasing and tempo soon lead you to proper identification. A titmouse enjoys a well-stocked feeder and is a nice neighbor for he enjoys singing and the clear whistled notes add a touch of nature to a cold winter day. - Trypanosoma Ziemanni, from the gut of the gnat
Trypanosoma Ziemanni, from the gut of the gnat - 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. - Trout

Trotting across a field - Tree-porcupine
The Mexican Tree Porcupine [Cercolabes (Sphingurus) novae-hispaniae], an animal of 95 cM. total length, of which about a third must be counted for the tail, inhabits the east coast of Mexico. The shiny hairs are very dense and soft, a little frizzy and so long, that many spines are completely covered by them. The spines are also missing from the parts, with the exception of the lower neck, on the inside of the legs, on the snout and on the rear half of the tail, which is covered from above naked, from below with black, on the sides with yellow brushes. - Tree Swallow
Tree Swallow Iridoprocne bicolor The frost hardly has left the ground, or the peepers and cricket frogs assembled their chorus, when flocks of these swallows can be seen winging their way northward. First flights include only the rugged males which arrive well in advance of their mates. They also are one of the last species of swallows to migrate in the fall. These birds show whitish under parts, while the upper parts are a greenish steel-blue. Western observers might confuse this bird with the Violet-green Swallow but remember that the latter shows a conspicuous white patch on each side of the rump. Tree Swallows prefer a location near water and soon will occupy holes in stumps so located: however, bird houses are acceptable. They do not choose to nest in colonies and will defend their nesting site with vigor. Those who erect nesting boxes for these swallows might find it necessary to help them evict House Sparrows which often take a liking to their homes. Flying insects form the major portion of this bird’s food. These include numerous mosquitoes and other insects which hatch on or near water, for that seems to be their favorite feeding ground. Other foods include bayberry and wax myrtle berries, which are sought during migration. - Trapping a polar bear

Tiger snake - Three Spined Stickleback
The male stickleback, as many of you may know, builds a wonderful nest, in which, when finished, he invites his chosen mate to lay her eggs. As soon as these precious treasures have been entrusted to his care, he makes himself their sole guardian, forcing currents of fresh water through the nest by the violent fanning motion of his breast-fins, and driving away all that come near. Strangely enough, he has to exercise the greatest care to keep out his mate, who would eat every single egg if she could but get the chance! - Thirteen-Spotted Lady Beetle

- The ‘Wonderful Cynocephalus’
For a trainer to break a monkey so as to ride a horse, carry a miniature flag, and hold on by the reins, is commonly considered a remarkable achievement. Occasionally though a monkey rider has been exhibited who has really performed in a manner not merely absurd. The most notable example of this kind was a huge ape of the cynocephalus or dog face family, exhibited in the winter of 1867–8 at Lent’s New York Circus, under the title of the “Wonderful Cynocephalus.” - THE ZOEA OF THE COMMON CRAB

- 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. - The yellow fever mosquito (Aëdes calopus)
- The Woolly Kangaroo
The Woolly Kangaroo - The White Yak of the Asiatic Mountains
This animal has a thick coat of long, silky hair, which hangs nearly to the ground. Ropes and cloth are made from it. The tail is just a great[96] bunch of long hair. The Yak does not bellow like the ox but gives a short grunt. Its milk is very rich, and fine butter is made from it. - The unicellular parasite Benedenia, from the gut of the common Poulp or Octopus
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 two wise cart-horses
Cart-horses, though heavy-looking animals, are more sagacious that their more gracefully formed relatives. A cart-horse had been driven from a farmyard to the neighbouring brook early one morning during winter to drink. The water was frozen over, and the horse stamped away with his fore-feet, but was unable to break the ice. Finding this, he waited till a companion came down, when the two, standing side by side, and causing their hoofs to descend together, broke through the ice, and were thus enabled to obtain the water they required. - The Two White Birds
The Two storks - The Three-banded Armadillo. An Animal in a Coat of Mail
The armadillo is an American animal, and is found in our country in the state of Texas. It goes south from there through Mexico and on to South America, where it is found everywhere. It lives in large numbers in the woods and on the great grass plains. In its food and habits it is much like the hedgehog, and like it burrows in the ground. To do this it has very strong claws, and these it can use to defend itself when it takes a fancy to fight. - The Tasmanian 'Mountain Shrimp'

- 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. - The Striped Zebra of Africa
The Zebra, one of the most beautiful of animals, from its handsomely striped skin, is a member of the horse family, but one of which we do not need to speak, since it is found only in a wild state. It has in some cases been tamed and trained to harness, but it is an obstinate and hot-tempered brute, so that few have tried to tame it. - The Starling. One of the Talking Birds
Have you ever seen a Starling and heard one talk? If not you have missed a treat, for this bird has fine powers of speech. He can whistle, croak and talk and is one of the choice delights of many a cottage home in Europe. He has lately been imported into this country. The common starling is a very pretty creature, clad in brown, with purple and green hues, and a buff-colored tip to each feather which gives the bird a fine speckled appearance. In its wild state it has a soft and sweet song, and in a cage is a pert and friendly house pet, one that mocks the songs of others, learns to whistle tunes, and can talk as clearly as many of its keepers. I must tell the story of a pair of very cute and lively starlings, as it is told us by the gentleman in whose house these birds were born and brought up - The Spine

- The short strap in use
A common breaching strap is used to strap up the foot. For using, open the loop, keeping the buckle on the outside, put the loop over foot, then raise foot and pass the strap around the fore-arm from the inside, and buckle it tight; this holds the foot up firmly.
