NEW MOTION PICTURES.

HUMAN BODY PROCESSES.

, Taking motion pictures inside the human body, within the chest, is the latest development in the motion picture art, as exhibited, by Dr. Wernor Siebert, of the Charite Hospital, in Germany. The device which permits the pictures to be made is, according to Dr. Siebert, expected to be useful in many scientific investigations, such as determining how the lung tissues work to absorb oxygen from the air, as well as what hapepns to these tissues when subjected to various types of disease.

The new device is not a microscopic motion picture camera; this would be too difficult a task for even the best of technicians to work out. It is a long narrow tube equipped with special lenses and a tiny electric torch. It may bo inserted down tho bronchial tube, into the lung. The other end of the tube, %vhich is equipped with other lenses on the same optical centre as those inside tho lung, is then connected to an ordinary motion picture camera. Whon the lights are turned on a motion picture of the lung tissue may be taken by directing the light, reflected from the walls of the lung, up through tho tubo to the other lenses, which focus the rays on the eye of the motion picture machine. In one tost the tube was properly placed in a part' of the left lung next to the heart and the internal lense transmitted the view to the camera and recorded on tho moving film the rhythm of the beating heart of the patient, just as if tho chest had been opened. This unique lung camera, it< is suggested, will probably become useful in medicine for the diagnosis of obscure cases of tuberculosis and other lung disorders.
