the visitor should notice the Currie partridge, from Nepal, the Cape and bare-necked partridges of Africa, and the sanguine pheasant; in the second case, the common European partridge and quail, the red European partridge, the Indian olive partridge, and the Andalusian quail; in the third and last partridge case, Californian and crested quails, and the Indian crowned partridge. Next in order are the Grouse, grouped in two cases (104, 105). In the first of these cases the visitor will notice the wood grouse of Scotland, and the ruffed and other grouse of America; in the second case, the sand-grouse of the scorching deserts. The last case of the scraping birds is occupied by the Sheathbills, which, as the visitor will perceive, closely resemble grouse. They are from South America; the tinamous, from the warmer parts of the Continent; and the megapodius, of Australia and the Asiatic islands. It now remains for the visitor to notice a few of the paintings suspended in this compartment, above the wall cases. These paintings include a copy of Klingstad's portrait of Peter I. of Russia, three historical portraits, presented to the museum by the Rev. A. Planta, and a hunting scene by Geo. B. Weenix. The visitor should now advance into the fourth compartment of the gallery, the wall-cases of which are devoted to the specimens of WADING BIRDS. Most interesting families of birds are included in this order. First, there are the Ostriches, which are the envy of all people cursed with weak digestive powers; then there is the Dodo, with its mysterious and half-told history; also the Bustards, the Coursers, the Plovers, the Cranes, the Storks, the Sandpipers, the Snipes, &c. These varieties of wading birds are carefully classed, and represented in the compartment of the gallery to which the visitor has now worked his way. First in the order of arrangement stand the ostriches, occupying the cases (107, 109). Some naturalists refuse to class ostriches with the order of wading birds, and elevate them to the dignity of a distinct order, Cursores, or runners; but in the museum, as the visitor will perceive, they are at the head of the wading order. Unscientific people know more about the ostrich than about most other birds of foreign climes. Few people have not heard that the egg of the ostrich weighs three pounds--that the sun is the bird's Cantelo--that he has only two toes to each foot--that he sometimes exceeds six feet in height--and that it would not be an act of madness to back a stout specimen, for speed, against an average horse. The digestion of the ostrich has been considerably strengthened in the minds of unscientific persons by imaginative travellers; the fact being that these birds live upon vegetable food, occasionally swallowing stones, or a bit of iron, in aid of that digestion which has been so misrepresented. In the cases before the visitor are the African ostrich, and his relations, the
