ABSOLUTELY INSTANTANEOUS PHOTOGRAPHY.

Probably nothing since the production of the famous photographs of Watron of horses in motion has attracted more attention in that line than an exhibition now being made in New York of a photograph taken by an army officer with Anthony's instantaneous collodion. An old army mule, condemned to death, was killed by a small charge of dynamite placed on his neck and exploded by electricity. The picture represents the mule standing with his head entirely blown oil , , and the rope with which he w.is tied to a short stake in the ground in the same position that it was when tied to his head, as it had not time to fall to the ground. The slide of the camera was dropped by the same charge of electricity that exploded the dynamite. Several years ago bronze remains were dug up in the island of Fiincn, Denmark, but no one knew what bad been their use. Lately Dr. H. Peterson was fortunate enough to find under the earth in Jutland what he considers to bo ,1 state carriage of the fourth or fifth century. It has ornamental woodwork. On the wheels were bronzes just the same as the ones discovered in Fmien. Engravers and watchmakers in Germany are said to harden their tools in sealing-wax, making them white-hot and plunging them into the wax, withdrawing on the instant and plunging again until too cold to enter the wax. The steel is said to thus become almost as hard as the diamond, and to bo well fitted, when touched with a little oil or turpentine, for engraving or piercing the hardest metals. A short but excellent paper on insomnia and other troubles connected with sleep in persons of gouty disposition has appeared in the current number of Brain. The writer, Dyce Duckworth, deprecates the use of socalled hypnotics as means of relief, aud he says that strict attention to diet, a free dilution ol the blood with bland fluids, regulated exercise of both mental aud bodily faculties, together with occasional mercurial purgatives, will commonly avail to overcome the misdirected tendencies aud to secure good nights for sufferers.
