With respect to the diversity of these two species, our presumption is founded, 1. On the difference of their external form; 2. On the colour and disposition of the hair; 3. On the difference which is found in the proportion of their skeletons; and 4. On the first two mentioned being natives of the southern countries of Africa, and the two that we are now treating of, being natives of Bengal. This last consideration is of as great weight as any of the rest, for we have had sufficient proofs, that in wild animals the distance of climate is a sufficient mark of the remoteness of the species. Besides, the malbrouck and the bonnet chinois, are not the only species or breeds of monkeys which are found in Bengal. By the testimonies of travellers there seem to be four varieties, white, black, red and grey; they likewise tell us that the black kind are more easily tamed than any of the rest. Those we saw were reddish, and appeared very docile and familiar. "These animals, according to travellers, plunder whole fields of grain, and plantations of sugar-cane; and while one stands centinel on a tree, the others load themselves with the booty. If any person appears, the centinel gives notice by crying _houp, houp, houp_, which the rest perfectly understand, and all at once throw down the plunder which they hold in their left hands, and scamper off upon three legs; if close pursued they also throw down what they have in their right, and save themselves from their pursuers by climbing up trees, which is their general abode. They leap from tree to tree, and even the females, though loaded with their young ones, leap like the others; but they sometimes, in their haste, miss their aim and fall. They are very difficult to render in any degree docile, and are never so far tamed as to be suffered to go unchained. Even in their own country they will not produce unless at perfect freedom in the woods. When they cannot procure fruits they feed upon insects, and sometimes go to the sides of the rivers, for the purpose of catching fish and crabs, the latter of which they take by watching the opening of its claws and then putting their tails between; the crab instantly closes them, when they, with all speed, drag it ashore, and eat it at leisure. They are fond of cocoa-nuts, and are very expert in extracting the juice for drink, and afterwards getting at the kernel, the shell of which is generally made use of as a snare to catch them; a small hole being made in one of them, the animal who meets with it thrusts his paw in with difficulty, when those who have laid the trap run and seize him before he can disengage himself. They sometimes place bamboos on the tops of trees for the purpose of extracting the _zari_, which drops from them, and which they drink. In the provinces of India, where the Bramins reside, and whose religious tenets do not allow them to kill any animals, the monkeys are almost numberless. They assemble in
