- Crested Flycatcher
Myiarchus crinitus Flycatchers can be, and often are, noisy birds. They seem to enjoy life and want the world to know how they feel about it. The Crested Flycatcher is no exception. To hear this bird at his best, stroll quietly thru some heavily-wooded area. You scarcely are aware of the flute-like tones of the Wood Thrush in the distance, drum of the Downy Woodpecker, the bubbling tones of the Carolina Wren. All is serene. Suddenly a loudly-whistled “wheeep,” followed by a series of equally loud rolling notes, shatters the air. That is the Crested Flycatcher. You might see him sitting quietly, peering intently at every leaf and branch, slowly moving his head so nothing will be missed. Then you will see the rufous tail, yellow belly, olive head and back, grayish throat and 2 wing bars. You might see the slight crest from which he gets his name. He is a trim bird almost robin size. - Cross section of foot of a horse
Anatomy of the Foot.—This illustration represents the foot of a horse sawed from above the fetlock down through the center of the foot. It shows the structure of the foot, the name of each part being given according to number. 1. Lower end of large metacarpal, or cannon bone. 2. Bursa, which secretes the joint oil that lubricates the place where the tendon, or cord, on the front of the leg passes down over the front of the fetlock joint. This is important as it sometimes gets injured and becomes enlarged. It is then called a bursal enlargement, and is of the same nature as a wind gall. 3. Fetlock joint. 4. Os suffraginis, or large pastern bone. 5. Pastern joint. This joint is important; when diseased it is the seat of a high ringbone. 6. Os coronae or small pastern bone. 7. Coffin joint. This joint is important, for when it is diseased it is known as a low ringbone. 8. Wall of the hoof. 9. Os pedis, or coffin bone. 10. Sensitive wall, or quick of the foot. 11. Sensitive sole, or quick of the foot. 12. Frog of the foot, or horney frog. 13. Plantar cushion, or fatty frog. 14. Navicular bone. This is also important, for when diseased it is the seat of navicular, or coffin joint lameness. 15. Back tendons below the fetlock. 16. Sesamoid, or fetlock bones. 17. Skin. 18. Back tendons above the fetlock. - Cross section of the larva of the browntail moth showing the tubercles bearing the poison hairs
- Culex larva showing details of external structure
The larvæ are elongate, with the head and thorax sharply distinct. The larval antennæ are prominent, consisting of a single cylindrical and sometimes curved segment. The outer third is often narrower and bears at its base a fan-shaped tuft of hairs, the arrangement and abundance of which is of systematic importance. About the mouth are the so-called rotary mouth brushes, dense masses of long hairs borne by the labrum and having the function of sweeping food into the mouth. The form and arrangement of thoracic, abdominal, and anal tufts of hair vary in different species and present characteristics of value. On either side of the eighth abdominal segment is a patch of scales varying greatly in arrangement and number and of much value in separating species. Respiration is by means of tracheæ which open at the apex of the so-called anal siphon, when it is present. In addition, there are also one or two pairs of tracheal gills which vary much in appearance in different species. On the ventral side of the anal siphon is a double row of flattened, toothed spines whose number and shape are likewise of some value in separating species. They constitute the comb or pecten. - Culex sollicitans. Female

Curiously marked white and black cat - Curlew ( Numenius arquatus )
Numenius are slender-built Birds with very long, weakly curved downward, high at the root, gradually thinning beak forward; with the exception of the horn-like spire, it is covered with a soft skin; the upper jaw is slightly longer than the lower jaw and slightly curved over it. The legs are slender and high, without feathering well above the hock; all three prongs are joined together by clear webbing. In the large, pointed wings the first flight is the longest; the medium-long tail composed of twelve feathers is rounded at the tip. The hard, close-fitting plumage is reminiscent of that of the Lark by its color, and is similar in males and females to each other and in the different seasons.

“The body of this creature is covered with crustaceous or shelly plates, which overlap each other, and admit both of a lateral and vertical motion between them. Their ends do not meet on the side, but have sufficient space between them for the insertion and play of the organs of respiration. The rostrum, or beak, is short and pointed: it is a prolongation of the first segment which forms the head. A little above the beak, a single eye is imbedded beneath the shell, of a dark crimson colour, nearly approaching to blackness. The true form of this organ it is difficult to determine. Mr. Baker gives it the shape of two kidney-beans placed parallel to each other, and united at their lowest extremities. When viewed laterally, it appears round, while in some other positions it is square.” The eggs are curiously placed in two bags, presenting an appearance similar to clusters of grapes, and of considerable magnitude, compared with the size of the animal. These egg-bags are seen in the engraving, (which represents a female,) projecting from each side of the hinder portion of the shell. The centre of each egg is of a deep opaque colour, which in some specimens is green, in others red. The young of the Cyclops, when first excluded from the egg, are extremely minute, and so different from the mother, that Müller has described them as forming two distinct genera. - Cyrtanthus Angustifolius

- Dancing Bears in Costume
Little bears are intensely amusing, and they display a great fondness for romping and playing. We have known of hunters bringing cubs home, and adopting them, as it were, into their families, the bears becoming exceedingly familiar, sleeping with the children, and eating from their bowls of bread and milk, climbing into the hunter’s lap and licking his face, and, in fact, making themselves perfectly at home. As they grow old, however, they are liable to become enraged at teasing or other provocation and to be dangerous. - Dancing Mania

The chigoes, or true chiggers, are the most completely parasitic of any of the fleas. Of the dozen or more known species, one commonly attacks man. This is Dermatophilus penetrans, more commonly known as Sarcopsylla penetrans or Pulex penetrans. This species occurs in Mexico, the West Indies, Central and South America. The males and the immature females of Dermatophilus penetrans closely resemble those of other fleas. They are very active little brown insects about 1-1.2 mm. in size, which live in the dust of native huts and stables, and in dry, sandy soil. In such places they often occur in enormous numbers and become a veritable plague. - Desert jumping mouse
Although these animals are numerous in the regions they inhabited, they are rarely seen here. They cannot be called shy, but they are restless and fearful and go to their burrows at the slightest, and as soon as they see a foreign object, as possible, to their burrows. - Devon Yearling Heifer, shown at Croydon, 1875
- 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. - Diagram of a longitudinal section of a mosquito
It is well known that mosquitoes, when they bite, inject into the wound a minute quantity of poison. The effect of this varies according to the species of mosquito and also depends very much on the susceptibility of the individual. Soon after the bite a sensation of itching is noticed and often a wheal, or eminence, is produced on the skin, which may increase to a considerable swelling. The scratching which is induced may cause a secondary infection and thus lead to serious results. Some people seem to acquire an immunity against the poison. The purpose of this irritating fluid may be, as Reaumur suggested, to prevent the coagulation of the blood and thus not only to cause it to flow freely when the insect bites but to prevent its rapid coagulation in the stomach. Obviously, it is not developed as a protective fluid, and its presence subjects the group to the additional handicap of the vengeance of man. As to the origin of the poison, there has been little question, until recent years, that it was a secretion from the salivary glands. Macloskie (1888) showed that each gland is subdivided into three lobes, the middle of which differs from the others in having evenly granulated contents and staining more deeply than the others. - 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. - Diagram of the senses, the humours, the cerebral ventricles, and the intellectual facultie
