_Catlin's Indian Gallery, Egyptian Hall._--By a visit to this exhibition, every class of the community, old as well as young, will derive much instruction and gratification. Mr. Catlin's representation of the red races of North America, their country, their costumes, their sports, their religious ceremonies, and, in short, their manners and customs, so as to enable us to form a complete idea of them, is deserving of the utmost praise. There are above 500 subjects in these spacious rooms, from a wigwam to a child's rattle; and everything belonging to the various Indian tribes are before the spectator in their actual condition and integrity. There are, besides, a multitude of portraits of the leading warriors, &c., &c., and other pictures of dances, ball-play, ambuscading, fighting; the whole supplying by far the most ample and accurate history of them that has ever been published to the world. No book of travels can approach these realities; and after all we had read of the red men, we confess we are astonished at the many new and important points connected with them which this gallery impressed upon us. We saw more distinctly the links of resemblance between them and other early and distant people; and we had comparisons suggested of a multitude of matters affecting the progress of mankind all over the earth, alike illustrated by similitudes and dissimilitudes. ----*---- SCOTSMAN--EDINBURGH. _Mr. Catlin's Lectures on the North American Indians._--Numbers of fashionable persons still continue to attend the Rotunda to inspect the varied curiosities belonging to this interesting tribe. We have much pleasure in publishing the following testimonial from a gentleman well qualified to pronounce an opinion, on the remarkable fidelity and effect of Mr. Catlin's interesting and instructive exhibition:-- "Cottage, Haddington, 15th April, 1843. "DEAR SIR,--I have enjoyed much pleasure in attending your lectures at the Waterloo Rooms in Edinburgh. Your delineations of the Indian character, the display of beautiful costumes, and the native Indian manners, true to the life, realised to my mind and view, scenes I had so often witnessed in the parts of the Indian countries where I had been; and for twenty years' peregrinations in those parts, from Montreal to the Great Slave River north, and from the shores of the Atlantic, crossing the Rocky Mountains, to the mouth of the Columbia River, on the Pacific Ocean, west, I had opportunities of seeing much. Your lectures and exhibition have afforded me great pleasure and satisfaction, and I shall wish you all that success which you so eminently deserve, for the rich treat which you have afforded in our enlightened, literary, and scientific metropolis.
