_Catlin's Indian Gallery._--Mr. Catlin's gallery of Indian pictures and curiosities has recently been opened at the Arcade for the inspection of the citizens of Philadelphia. In common with other lovers of amusement, we have visited this collection, and have found that it fully justifies whatever has been said by those who visited it in Boston and New York, and described it as the most surprising, entertaining, and instructive exhibition which the efforts of American genius have ever brought before the country.... In this stage of human knowledge Catlin resolved to devote the labours of his life to exploring the condition, customs, character, and conduct of this people, and to bring home a record of their being, which should be to the world a possession for ever. He has fulfilled this purpose. He has lifted the veil on which was written "ignorance," and he has shown to his countrymen the peculiarities of a life which is competent to instruct philosophy with conclusions that it has never dreamt of, and entertain curiosity beyond the compass of the wildest fables. ----*---- THE PHILADELPHIA EVENING POST. The subjects of Mr. Catlin's pencil, his histories and delineations, are of a noble race. The Camanchees, the Mandans, the Pawnees, the Blackfeet, Sioux, Crows, Assiniboins, Omahaws, &c. &c., who have not yet sunk beneath the withering associations of white people, who on their native prairies stalk with noble pride and independence, who manufacture their own dresses from the skins of the mountain sheep and buffalo, and use their spears, bows and arrows, in preference to fire-arms, and with courtly pride and hospitality welcomed the artist, and honoured him for his talents of delineation, as a nobleman of nature, infinitely superior to the mercenary race of traders and Indian agents, who plunder and cheat them when opportunity offers. The Indian is truly fortunate in having so faithful and industrious a champion, historian, and painter as Mr. Catlin, who will no doubt rescue their name from the mass of trading libellers that have so long corrupted and then slandered them. With a remarkable assiduity and perseverance he has devoted many years of his life, and much pecuniary means, in preparing a magnificent collection of their dresses, instruments, ornaments, portraits, &c. For ourselves, we anticipate one of the most original and curious works that has been issued from the press for many years, for Mr. Catlin has struck out a new path to fame and fortune, and while he leaves a memorial of the true Indian uncorrupted native character, he makes a lasting name for himself. ----*---- THE NEW YORK EVENING STAR.
