SLOW LORIS.
Another of the slow-moving loris group. These animals are not shown to the general public at the Zoo, but kept in a specially warmed room.
The Aye-aye.
Last, and most remarkable of all these weird lemuroids, is the Aye-aye. It is placed in a group by itself, and has teeth like those of the Rodents, a large bushy tail, and most extraordinarily long, slender fingers, which it probably uses for picking caterpillars and grubs out of rotten wood. It is nearly as large as an Arctic fox, but its habits are those of a lemur. In Madagascar it haunts the bamboo forests, feeding on the juice of sugar-cane, grubs, and insects. The fingers of its hands are of different sizes and lengths, though all are abnormally long and slender. The second finger seems to have "wasted," but is said to be of the utmost value to its owner in extracting grubs and insects from the burrows in which they dwell, or the crannies in which they may have taken refuge. Very seldom is this animal seen alive in captivity. Although commonly called Aye-aye in this country, it is doubtful if this is really its native name. The aye-aye was long a puzzle to naturalists, but is now classed as a lemuroid.

TARSIER.
These little animals hop about in the trees like frogs. They are nocturnal, and seldom seen.
The living races of animals have thus far been reviewed along the completed list of the first great order—the Primates. Even in that circumscribed group how great is the tendency to depart from the main type, and how wonderful the adaptation to meet the various needs of the creatures' environment! The skeletons, the frames on which these various beings are built up, remain the same in character; but the differences of proportion in the limbs, of the muscles with which they are equipped, and of the weight of the bodies to be moved are astonishing. Compare, for instance, the head of the male Gorilla, with its great ridges of bone, to which are attached the muscles which enable it to devour hard tropical fruits and bite off young saplings and bamboos, with the rounded and delicate head of the Insect-eating Monkeys of South Africa; or set side by side the hand of the Chimpanzee with that of the Aye-aye, with its delicate, slender fingers, like those of a skeleton hand. What could be more diverse than the movements of these creatures, whose structure is nevertheless so much alike? Some of the lemuroids are as active as squirrels, flying lightly from branch to branch; in others, as the Slow Lorises, the power of rapid movement has disappeared, and been replaced by a creeping gait which cannot be accelerated. Already, in a single order, we see the rich diversity of nature, and its steady tendency to make all existing things serviceable by adapting other parts of creation to their use or enjoyment.
