Submarine Photography

A short tiiue ago Mr. Louis Bontoi brought himself to the knowledge oí scientific naturalist by nndertoiking au exploring tour of the Red Beu, from which he brought back a Btranfte atid curious collection of fish and sbells. embracing several specimens entirely un known. Continuing his researéhes on the coaat of France, Mr. Bon ton as sumed a divcr's costnme in order to bBerve at the bottom of the sea the mtta morphosesof certaiu moUnsks imp ble to cultívate in nqnaria. He wua struck with the' wondeEful bcaniy ot submarine landscapes and resolved lo photograph wbut he conM, ahice simple desoription would savor uj.j tuuch jí an overvivid imagitiatíoii. At'first he worked in sliallow water with a watertight apparatu, and the clearness of the water allo wed hi:n sufficient light to sensiti'ze the platea. But proportionally as the water deepened clearness dimiuished, and tRe motion of the waves clouded his proofs. Theu the young scientist conceived the idea of utilizing magnesium in an apparatus of his own invention. This apparatus oonsists essen cially in a barrel filled with oxygen and sunnounted by a glass bell contaminar an alcohol lamp. On the fíame of the lamp, by means ol a mechanical contrivance, powdered magnesium is thrown, flaring as of ten as a view is taken. The barrelis pierced with holes on the lower side in such a manner that as the oxygen diminishes the sea water enters, so preserving the equilibrium between esternal and internal pressure. By the aid of this machine he has already made great progress in a directioa new to naturalista and one likely to confer permanent benefits in the resulta obtained by their science. - Exchange.
