The prettiest of all monkeys is the Marmozet; the Ouistiti of Buffon; the Simia Jacchus of Linnæus. It is extremely sensitive to cold; nevertheless, if plentifully supplied with wool, cotton, and other warm materials, will live for years in this climate. Dr. Neill of Edinburgh, that most excellent protector and lover of animals, brought one from Bahia, which he found great difficulty in training. It even resisted those who fed it, not allowing them to touch it, putting on an angry, suspicious look, and being roused by even the slightest whisper. During the voyage it ate corn and fruit, and when these became scarce, took to cockroaches; of which it cleared the vessel. It would dispatch twenty large, besides smaller ones, three or four times in each day, nipping off the head of the former, and rejecting the viscera, legs, and hard wing cases. Besides these, it fed on milk, sugar, raisins, and bread-crumbs. It afterwards made friends with a cat, and slept and eat with this animal, but it never entirely lost its distrustful feelings. Lieutenant Edwards, in his voyage up the Amazon, mentions a domestic white monkey, which had contrived to get to the top of a house, and no persuasions or threats could get him down again. He ran over the roof, displaced the tiles, peeped into the chambers below (for there are no ceilings in that country), and when called, put his thumb up to his nose. He was shot at with corn, but having found a rag, he held it up before him, and so tried to evade the shot; every now and then peeping over the top. At last he was left to himself; and when no endeavours were made to get him down, he came of his own accord. Captain Brown mentions a monkey, who, when he was troublesome in the cabin of a ship, was fired at with gunpowder and currant jelly; and in order to defend himself, used to pick up the favorite monkey, and hold him between the pistol and himself when it was presented.
