_Machine for Sharpening Knives at once,_

Consists of a number of steel cylinders grooved transversely, and placed
on two revolving axes parallel to each other, and so that the bosses and
recesses of the one fit into those of the other cylinder. Along these
the knife is drawn, and so is immediately sharpened.--_London Jour. of
Arts._

M. Astier has discovered that seeds which are electrified, run through
the first stages of vegetation more rapidly than others, and that China
roses submitted to this experiment, produce flowers sooner, and in
greater abundance.--_From the French._
