----*---- THE SPECTATOR. Catlin's Indian Gallery, at the Egyptian Hall, Piccadilly, is a museum of the various tribes of North American Indians. Mr. Catlin is an enterprising American artist, who has devoted eight years to the delineation of scenes and persons, and the collection of objects to form a permanent record of the characteristic features and customs of the different tribes of Indians in North America, now fast becoming extinct by the combined operation of smallpox, spirit-drinking, and war. The walls of a room 106 feet in length are entirely covered with portraits of Indian men, women, and children, in their respective costumes, some small whole-lengths, others busts the life-size, to the number of 310; and 200 views of landscape scenery, native villages, games, customs, and hunting-scenes, all painted on the spot. Besides the pictures, the dresses worn by several tribes, and a numerous collection of weapons, pipes, ornaments, &c., are arranged round the room; and in the centre is set up a wigwam of the "Crow" tribe, a conical tent twenty-five feet high, made of buffalo-skins, dressed and painted, supported by thirty poles meeting at the top, and capable of sheltering eighty persons. To attempt anything like a detailed description of the contents of such a museum would require a volume; to characterize it generally in our limited space is difficult. It would require hours of attentive study to become fully acquainted with the multifarious articles. The several tribes are distinguished in the catalogue: the dresses are all so fantastic, and the physiognomies so varied, that it would be difficult to class them. The dances and other amusements appear anything but gamesome; and the religious ceremonies of the Mandans, of which there are four scenes, are horrible in the extreme. It is their annual custom to assemble the young men in the "Medicine" or "Mystery" Lodge--the medicine-men are a sort of mixture of the doctor, priest, and sorcerer--and after being starved for four days and nights, they are tortured in the most cruel manner to test their powers of endurance. The animal character, sharpened and sometimes ennobled by the influence of moral qualities, is strongly expressed in all the heads.
