in front of him, and at each blow of the light switch told him to take hold of it, and at last, much to my surprise, he did so, taking it and holding it tremblingly in one hand. He would draw things towards him with a stick, and even use a swing for the same purpose. It had been put up for the children, and could be reached by Mickey, who now and then indulged himself with a swing on it. One day, I had put down some bird-skins on a chair to dry, far beyond, as I thought, Mickey's reach; but, fertile in expedients, he took the swing and launched it towards the chair, and actually managed to knock the skins off in the return of the swing, so as to bring them within his reach. He also procured some jelly that was set out to cool in the same way. Mickey's actions were very human-like. When any one came near to fondle him, he never neglected the opportunity of pocket-picking. He would pull out letters, and quickly take them from their envelopes. Anything eatable disappeared into his mouth immediately. Once he abstracted a small bottle of turpentine from the pocket of our medical officer. He drew the cork, held it first to one nostril then to the other, made a wry face, recorked it, and returned it to the doctor. Another time, when he got loose, he was detected carrying off the cream-jug from the table, holding it upright with both hands, and trying to move off on his hind limbs. He gave the jug up without spilling a drop, all the time making an apologetic grunting chuckle he often used when found out in any mischief, and which meant, "I know I have done wrong, but don't punish me; in fact, I did not mean to do it--it was accidental." Whenever, however, he saw he was going to be punished, he would change his tone to a shrill, threatening note, showing his teeth, and trying to intimidate. He had quite an extensive vocabulary of sounds, varying from a gruff bark to a shrill whistle; and we could tell by them, without seeing him, when it was he was hungry, eating, frightened, or menacing; doubtless, one of his own species would have understood various minor shades of intonation and expression that we, not entering so fully into his feelings and wants, passed over as unintelligible.* There is a third species of monkey (Mycetes palliatus), called by the natives the congo, which occasionally is heard howling in the forest; but they are not often seen, as they generally remain quiet amongst the upper branches of particular trees.
