It gives me great pleasure in being enabled to add my name to the list of those who have spontaneously expressed their approbation of Mr. Catlin's collection of Indian Paintings. His collection of materials places it in his power to throw much light on the Indian character; and his portraits, so far as I have seen them, are drawn with great fidelity as to character and likeness. H. SCHOOLCRAFT, Indian Agent for Wisconsin Territory. ----*---- Having lived and dealt with the Black feet Indians for five years past, I was enabled to recognise _every one_ of the portraits of those people, and of the Crows also, which Mr. Catlin has in his collection, from the faithful likenesses they bore to the originals. _St. Louis_, 1835. J. E. BRAZEAU. ----*---- Having spent sixteen years in the continual acquaintance with the Indians of the several tribes of the Missouri represented in Mr. Catlin's Gallery of Indian Paintings, I was enabled to judge of the correctness of the likenesses, and I _instantly recognised every one of them_, when I looked them over, from the striking resemblance they bore to the originals; so also of the landscapes on the Missouri. HONORE PICOTTE. ----*---- The portraits in the possession of Mr. Catlin of Pawnee Picts, Kioways, Camanches, Wecos, and Osages, were painted by him _from life_, when on a tour to their country with the United States Dragoons. The _likenesses_ are good, very easily to be recognised, and the _costumes_ faithfully represented. HENRY DODGE, Col. of Drag. R. H. MASON, Major of ditto. D. HUNTER, Capt. of ditto. D. PERKINS, Capt. of Drag. M. DUNCAN, ditto. T. B. WHEELOCK, Lieut, ditto. ----*---- We have seen Mr. Catlin's Portraits of Indians east of the Rocky Mountains, many of which are familiar to us: the likenesses are easily recognised, bearing a strong resemblance to the originals, as well as a faithful representation of their costumes. J. DOUGHERTY, Indian Agent. J. GANTT. _November 27th, 1837._ ----*---- We hereby certify that the portraits of the Grand Pawnees, Republican Pawnees, Pawnee Loups, Tappage Pawnees, Otoes, Omahaws, and Missouries, which are in Mr. Catlin's Indian Gallery, were painted from life by Mr. George Catlin, and that the individuals sat to him in the costumes precisely in which they are painted.
