The great merit of these oil sketches is their manifest correctness, not to a line or the mere making out of a horse's head or some portion of dress, but to the action and the scene. Not only the portraits, but the landscapes and groups, have a certificate of identity. We recommend to all the "Descriptive Catalogue," which is very amusing, and is necessary to the elucidation of customs and localities. At the private view to which we were invited on Tuesday there was a very numerous assemblage of persons of distinction. ----*---- NEW COURT GAZETTE. _Catlin's Indian Gallery._--This interesting exhibition consists chiefly of portraits of the most distinguished warriors and chiefs of the various tribes, besides views of fine scenery, buffalo hunting, war and other dances; a vast variety of weapons, dresses, some scalps, a wigwam, &c. The collection also contains some of the females of note, who display attractions of feature and expression which would not discredit the most civilized people. Amongst the chiefs of greatest notoriety here is the celebrated chief "Black Hawk." The eldest and second sons of this chief are here also, and are worthy of the sire from whom they sprung. There are several other distinguished warriors of this tribe and others, amounting to some hundred portraits. We can strongly recommend our readers to attend; they will then, for the first time, become acquainted with the real manners and customs of these "before-misrepresented people," who are fast sinking from the face of the earth. ----*---- LONDON SATURDAY JOURNAL. _Mr. Catlin's Indian Gallery._--In visiting it, indeed, the town-bred admirer of the freedom and grandeur of "savage life" might find somewhat, at first sight, to feed his sentimental fancies. Round the room, on the walls, are portraits of Indians, remarkable specimens of the true animal man; arrayed in their holiday dresses, tricked out in all the variety of savage fancy, and many of them as evidently and consciously "sitting for their portraits," as the most pedantic and affected superficialist of civilization. With these we have many glimpses of the scenery and state of existence connected with "life in the wilds." The far stretching prairie; the noble river and its "reaches," and "bluffs," and waterfloods; the shaggy bison, whose tremendous aspect makes him fearful, even in the stillness of a picture; the more terrible grisly bear; the Indian "at home," and the the Indian "abroad," with stirring hunting scenes, enough to rouse one's blood, and to make an unfledged adventurer long to dash away, and try one's skill and courage in an encounter with horned monsters, or even that "ugly creature" before whom the "strongest bull goes down." ----*---- KIDD'S LONDON JOURNAL.
