7 Water oblained by Boring. Artesian wells have been very successfully constructed in some parts of France. A letter from M.

A leaden weight of eight pounds, supported by a string, being placed in the tube, was rapidly thrown out by the water. The water, which at first had a peculiar taste, but not disagreeable, is now very limpid and insipid, and its temperature 66 degrees of Fahrenheit.

perb designs have at times been executed by the best binders of this country and France. M. Didot, bookseller, of Paris, presented a copy of the L‘Henriade,” published by himself, to Louis XVIII., most elegantlq ornamented in this style. It was executed by M. Bellier, bookblntler, of Tuurs, and presented, on one side, a miniature portrait of Henry IV., and, on the other, a similar one of Louis XVII[., both perfect likenesses. The greatest difficulty consisted in the portraits, which were tirst imprinted on paper, very moist, and immediately applied to the cover, on which they were impressed with a flat roller. When perfectly dry, they were coloured with all the art of which the binder was capable, and the other ornamental paintings executed by hand. This proceeding requires great care in the execution, and will be applicable to any design where the binding will justify the expense. [Lo&. Mech. Mug.
