a pleasing undulation of surface that gives infinite interest to a promenade. The botanical part is flat and even, divided by walks into compartments, each forming a small distinct garden by itself. These are either enclosed by well-kept hedges, or by rails and rustic fences of every possible useful fashion--which may serve as models for those in want of such things. These little gardens each contains some family of shrubs or plants, and are all arranged according to their respective climates. The dividing walks form most agreeable promenades, as was evinced by the number of people I found lounging in them, many evidently not taking any interest in the botanical treasures around. This flat space is bounded on one side by a magnificent avenue of elms, under the shade of which are numerous _vendeurs de boissons_ and _de pâtisserie_, as well as one or two regular restaurateurs. On the other side, the ground, swelling gently into hill and dale as it were, is fitted by enclosures of simple rail or strong stockade, as occasion may require, for the confinement of an elephant or a deer. Here in little paddocks, with room to move about and a house to shelter them, we find a number of animals, who, perhaps, well fed as they are, little regret the loss of liberty. The elephant even has a pond to wallow in, to the great amusement of the _badauds_ who constantly throng the stockade. The more savage beasts (_genus Felis_, &c.) are confined as with us, in dens. It was only in looking over the catalogue of the menagerie, and finding the beasts enclosed in the paddocks classed as ruminant and _fauve_, that I remembered we have no term to translate the latter word. This part of the establishment is very entertaining, and I lounged away a great part of my time in wandering about the winding walks between the enclosures, amused by the curiosity and _naïveté_ of many of the visitors. The menagerie is separated from the gardens by a rampart and ditch. In the latter are the bears, great favourites with the public, particularly the boys, of whom numbers are always hanging on the wall, watching the heavy animals climbing a high pole set for the purpose. The hothouses contain all sorts of things; but what interested me were the palms--some of these I saw out of doors. Just by the hothouses is a high mount, ascended by a spiral path, bearing a sort of temple on the top, whence there is an extensive and much-vaunted view over the city and neighbourhood; but not half so extensive as, nor in any way comparable to, those from Belleville, Montmartre,[24] and, above all, from Mont Aurelian. The School of Comparative Anatomy is very interesting: it contains perfect skeletons of almost every species of animal, bird, or fish, from the most diminutive to the largest--from the minnow to the whale, from the shrew-mouse to the mastodon, from the humming-bird to the condor.
