Cinematographing a Man’s Stomach. The latest thing in moving pic tares is that obtained through the agency of X-rays. It was report ?d a little while ago that a Dir-h Wentist had shown to a Congress of German scientists a cinemato-

graphic representation of the beating of a human heart. That t s jNMMdble to take such photographs Mth a considerable measure of success is proved by the films which bare just come into the possession jrf Messrs. Pathe Freres. They show in a dramatic way the exiv. j Snation of a patient’s stomach by a doctor who employs X-rays for the purpose. The man's interior is plainly visible upon the screen, and * cinematograph picture is :hns easily obtainable in the ordinary way.. Extraordinary. A Cherbourg dockyard mechanic named Debrix, at the French naval machinery workshop, has invented an apparatus by which Hertzmn waves can, he claims, be connected with the Morse telegraph, thus permitting ordinary and wireless telegraphy to be combined. The apparatus is now being examined by rhe Invention Committee of the Navy. If it is practicable it would place an liner in uninterrupted communication with all the Continental ’rtelegraph offices. The application of the system would enable the »•?- toblishment of high -tension .-ta"tions to be dispensed with, ard "those already existing along Die const would suffice for immediate 'transmission.—Morning Leader.

Every new invention carries *vil -in ita train. The British Medical Journal points out that among distfaetivdy modem diseases are .he gmsoaung produced by the fumes of or acetylene; the rwadaebe, dyspepsia, cardiac fail* and sensory disturbances to the manufacture and jWaa of aniline dyes; the frothing of the fblood, known as caisson disease, which follows too rapid deeongnesmon in workers at the foundations of bridges; the functional 'jnenrosis known as telegraphists’ resulting from the use of the wßotae key; and the numerous affections of the skin, lungs, digestive tract, and eyes due to irritation by organic or inorganic dusts of industrial origin. Thia, it should be said. Mg no means exhausts our contem-
