"A small kidney shaped, pendulous bag of the size of a hen's egg, situated below the abdomen and peculiar to the male. It is brown and unctuous, and may be pressed out through two apertures. It is the strongest and most pungent of perfumes; the mere skin of the animal is sufficient to fill the place where it has been kept with a strong odor for a long time.In medicine it is used as an antispammodic. " — S. G. Goodrich, 1885

Galeopithecus is the generic name of certain mammals from the Malayan region, commonly (incorrectly) referred to as flying lemurs. The two species of Galeopithecus are now placed in a sub-order of Insectivora, and regarded as the vegetarian analogues of the insect-eating bats. The common species, G. volans, is about the size of a cat and has a flying-membrane.

The teeth are remarkable, the lower incisors being comb-like, while the upper outer incisor at each side has two roots. Galeopithecus primarily inhabit forests. They feed upon leaves, fruit, eggs, insects, and even small birds. They are nocturnal. Though incapable of true flight, they can take long, flying leaps.

This illustration shows a head of a Gems'bok. A Gems'bok (Oryx Gazella) is a species of South African antelope. It is a heavy, stout animal, about the size of a stag, with rough, reversed hair on the neck and along the ridge of the back; large pointed ears; and almost perfectly straight horns in the plane of the forehead, little diverging, and ringed for about half their length. These horns have been known to reach a length of 47 1/2 inches. The gems'bok was, at one point, close to extinction.

The Great Dane is a dog which has at different times been called the 'boar-hound', the 'German Mastiff', and the 'Ulmer dog'. It first began to attract attention about 1870. The grand figure, the bold outlook, and the commanding appearance of the type commended it to certain enthusiasts; and when it was found to be faithful, and intelligent, and of unfailing courage, it soon came into favor. The latest development of the breed is a harlequin-colored or black and white dog, sometimes with a wall eye and mottled nose. The Great Dane stands 34 in. high, and weighs as much as 180 lbs.; though the bitch is considerably smaller and lighter.

The Jumping Mouse (Zapus hudsonius) is a N. American, jerboa-like mouse, with long hind legs, a very long tail, and five complete toes on the hind foot. It is warmly reddish above, white on the lower parts, and progresses, when alarmed, by a series of rapid leaps, each of several yards, when in haste. it dwells in open, grassy places, skulking about under the herbage and feeding mostly on grass seeds; there it places its nest (a hollow ball of grass) in some small hole or burrow, and spends the cold months in a long hibernation.

Due advantage is taken of this arrangement by the seal when swimming, the animal rotating on its long axis, so as to present the lower portion of the body and the feet obliquely to the water during the return stroke, and the flat, or the greatest available surface of both, during the effective or forward stroke."—Pettigrew, 1874
