Bats of the ordinary size are very numerous in Jamaica. They are found in mills and old houses. They do great mischief in gardens, where they eat the green peas, opening the pod over each pea, and removing it very dexterously. Gilbert White, of Selborne, first noticed a large species of Bat, which he named _altivolans_, from its manner of feeding high in the air. In the extent of its wings it measured 14-1/2 inches; and it weighed, when entirely full, one ounce and one drachm. It is found in numbers together, so many as 185 having been taken in one night from the eaves of Queens' College, Cambridge. In the Northern Zoological Gallery of the British Museum are representatives of the several species of Bats, all bearing a family resemblance to each other. In England alone there are eighteen known species. Here is the curious leaf-nosed Bat, from Brazil, supposed to excel in the sense of smell; also, the Vampire, or large blood-sucking Bat, from the same country; and the different kinds of fruit-eating Bats, found in America and Australia, and sometimes called flying foxes, on account of their great size. The Bats of temperate climates remain torpid during the winter. Gay has these lines:-- "Where swallows in the winter season keep; And here the drowsy bat and dormouse sleep." Young Bats have been taken, when hovering near the ground, by throwing handfuls of sand, but they rarely live in confinement: they often die within a week after their capture. A Bat, taken in Elgin, gave birth to a young one, which was for two days suckled by its parent. Before she reached the age of three days the young bat died, and the parent only survived another day to mourn her loss. Sometimes females, when taken, have young ones clinging to their breast, in the act of sucking; and the female can fly with ease, though two little ones are attached to her, which weigh nearly as much as the parent. To return to an exaggeration of a famous old traveller. In "Purchas his Pilgrimage," the materials for which he borrowed from above thirteen hundred authors, when speaking of the island of Madura, in the South of India, he says:--"In these partes are Battes as big as Hennes, which the people roast and eat." THE HEDGEHOG. Of this animal some strange things are recorded. It is placed by Cuvier at the head of the insect-devouring Mammifera. It is found in Europe, Africa, and India. Its body is covered with strong and sharp prickles, and by the help of a muscle it can contract itself into a ball, and so withdraw its whole underpart, head, belly, and legs, within this thicket of prickles: "Like Hedgehogs, which Lie tumbling in my barefoot way, and mount Their pricks at my foot-fall."--Shakspeare's "_Tempest_."
