also of their great curiosity regarding snake-like things and their doings, took a stuffed Snake to the Monkey-house of the Zoological Gardens. The excitement which was produced, he writes, was one of the most curious spectacles ever beheld. Three species of Cercopithecus were the most alarmed. They darted about their cages, and uttered sharp cries of danger, which were understood by the other Monkeys. A few young Monkeys and an old Anubis Baboon alone took no notice of the Snake. He then placed the stuffed specimen on the ground in one of the larger compartments. After a time all the Monkeys collected round it in a large circle, and staring intently, presented a most ludicrous appearance. They became extremely nervous, so that when a wooden ball with which they were familiar as a plaything was accidentally moved in the straw under which it was partly hidden, they all instantly started away. These monkeys behaved very differently when a fish, a mouse, and some other new objects were placed in the cage; for though at first frightened they soon approached, handled and examined them. He then placed a living Snake in a paper bag, with the mouth closed loosely, in one of the larger compartments. One of the Monkeys immediately approached, cautiously opened the bag a little, peeped in, and instantly dashed away. Then he witnessed what Brehm has described, for Monkey after Monkey with head raised high, and turned on one side, could not resist taking momentary peeps into the upright bag at the dreadful creature lying at the bottom. It would appear as if Monkeys had some notion of zoological affinities, for those kept by Brehm exhibited a strange though mistaken instinctive dread of innocent Lizards and Frogs.
