All these birds were comprehended by Linn?us under the generic name of Strix, but later naturalists have subdivided them into several genera, dependent on the size of the ears and of the ocular discs, on the presence or absence of two remarkable tufts of feathers on the head having somewhat the appearance of horns, and on the covering of the legs and feet. The Virginian Horned Owl is spread over nearly the whole continent of America from north to south. Its plumage is brown above, marked with numerous transverse black stripes, and the feathers of the under surface are of a dirty white, transversely striped with blackish-brown.
Such is a brief outline of the history up to the present period of the establishment known as the Tower Menagerie.[xvi] Of the animals contained in it during the summer of 1828, and of two others which had then recently died, the succeeding pages offer delineations, descriptions, and anecdotes. Among so numerous a collection of inhabitants, of such dissimilar habits, and brought together into one spot from such distant and various climes, some changes have almost necessarily taken place even while our work has been passing through the press; yet so excellent is the management of Mr. Cops, especially as regards cleanliness, that essential security of animal health, that not a single death has occurred from disease, and one only from an accidental cause: the secretary bird, having incautiously introduced its long neck into the den of the hy?na, was deprived of it and of its head at one bite. Other removals are owing to the spirit of commerce. The Cape lion, the chetahs, the Thibet bear, and the deep-blue macaw,
as two feet. They are well known as furnishing one of the most beautiful and ornamental productions which the animal kingdom[166] affords, as well as a valuable article of commerce, in the pure and polished ivory of which they are formed. They have been known to weigh as much as one hundred and fifty pounds, but their usual average is from fifty to seventy.
The Alligators constitute a natural subdivision of the genus, in which the snout is broad, blunt, and less produced than in the true Crocodiles; the fourth tooth on each side of the lower jaw enters a hole in the upper when the mouth is closed; and the toes are only half-webbed. They appear to be exclusively natives of America. The present species is distinguished by its broad and flat snout, with nearly parallel sides, united in front by a curved line; by the peculiar arrangement of its nuchal scales; and by the elevated internal margins of its orbits. Its colour is dark brown above, and somewhat lighter beneath. It is one of the most dreadful scourges of the countries which it inhabits, preying upon all kinds of animals that come within its reach, and sometimes even upon man himself. Our specimen was apparently very young, not measuring more than three feet in length; but during two years that it was kept in the Menagerie it was not observed to have at all increased in size. It was fed once a week upon raw
