_Catlin's Indian Gallery._--We alluded briefly a few days since to Catlin's Indian Gallery, now open in the saloon at the Arcade, and we again call attention to it as one of the most gratifying exhibitions of the day, to all who feel the slightest interest in the aborigines of our country, or desire to become acquainted with the topographical features of the great western wild. This collection is the result of years of toil and privation, sustained by a rare and commendable enthusiasm. Mr. Catlin, who is an artist of much ability, and is likewise in other respects well fitted for the task which he voluntarily assumed, devoted himself to a study of the Indian character, and steadily followed out his great object for a considerable length of time. He has visited many of the tribes who yet roam in their native wildness, and he became as it were domesticated among them to study their habits and dispositions, encountering all the perils and privations which necessarily attend an enterprise of this nature. In the course of his rambles, he made paintings of every thing calculated to give a vivid impression to others of the persons, events, and scenes which fell under his notice, and the result is a magnificent collection of portraits and views of the most interesting character, made still more attractive by an immense variety of Indian dresses, arms, and utensils of many kinds, which, with the illustrative scenes, give a clear idea of aboriginal characteristics, and form a pleasing evidence of the results which can be achieved by the untiring perseverance of a single man. Mr. Catlin has in this way made a contribution to American history which must gain for him an enduring fame. It should form the nucleus of a national museum, that posterity may have some relics of a people doomed to speedy destruction, as much by their own inflexible nature as by the rolling tide of civilization. ----*---- THE PHILADELPHIA GAZETTE. _Catlin's Indian Gallery._--We could scarcely recommend a more pleasing and instructive collection than this to the notice of the community. It is what only a Catlin, with his enthusiasm and perseverance, could have accomplished. To him the study of nature is most appropriate in her great hall or cathedral:-- "That vast cathedral, boundless as our wonder, Whose quenchless lamps the sun and moon supply; Its choir the winds and waves; its organ thunder; Its dome the sky." The boundless woods have been his home, and dwellers of the wilderness the sitters for his art. So far as Indian life is concerned, the reader will find a little of every thing in Catlin's gallery; not of faces merely, but of grand western life and scene. ----*---- THE WORLD.
