A Russian woman physician haf proved that infection may be carried by a bullet from the clothing to a wound. Using a Swiss military rifle, shots were fired—before and after the gun had become hot —through cloth saturated with cultures of various micro-organisms, and in every case the sterilized bullet took' up the germs from the cloth. Neither high velocity nor heat were sufficient to prevent Infection. Instantaneous photography Is being applied by a German biologist to an investigation of the action of Insects’ wings.- As many as 2.500 exposure" per second are obtained by revolving a cog wheel In the focus of concentrated sunlight, the photographic images of the insect being separated by means of a revolving mirror. A great difficulty is to get the insect to fly in the narrow limits in which it can be photographed. In a recent paper to th«l London Instltuton of the Mechanical Engineers, Mr. J. H. Wicksteed showed that spongy, malleable Iron, made direct from the ore, was much employed for tools and weapons about 400 B. C., the time of the earliest records of accurately known date, and received great attention in the tlnie of Homer, 880 B C. Until about 400 years ago, however, bronze held the field for objects that could not be shaped by band hammering.

There are, it would seem, many fine points In sculptural criticism which the art world, overlooks, tor Mr. St. Oaudens has told how recently he heard an Irishman, passing i Ms Sherman i statue, but lately unveiled In New-York, remark that It was all wrong; "for," said he, "would an illigant military gtntieman like the gineral be riding and lot the lady [Fame] walk?"
