silvery gibbon.—hylóbates leuciscus.

the different kinds of apes, which approach the nearest to the human figure, are distinguished from each other by the tail. their shrewdness is quite wonderful. it is said that, imitating the hunters, they will besmear themselves with bird-lime, and put their feet into the shoes which, as so many snares, have been prepared for them.[108] mucianus says, that they have even played at chess, having, by practice, learned to distinguish the different pieces, which are 103 made of wax.[109] he says that the species which have tails become quite melancholy when the moon is on the wane, and that they leap for joy at the time of the new moon, and adore it. other quadrupeds also are terrified at the eclipses of the heavenly bodies. all the species of apes manifest remarkable affection for their offspring. females, which have been domesticated, and have had young ones, carry them about and show them to all comers, show great delight when they are caressed, and appear to understand the kindness thus shown them. hence it is, that they very often stifle their young with their embraces. the dog-headed ape is of a much fiercer nature, as is the case with the satyr. the callitriche or “fine-haired monkey,” has almost a totally different aspect; it has a beard on the face, and a tail, which in the first part of it is very bushy. it is said that this animal cannot live except in the climate of ?thiopia, which is its native place.
