Nowadays when the physician is called to examine a person who has something seriously wrong with the stomach he' takes a look at the inside of that organ before deciding whether it is necessary to perform an operation or not. To see tho inside of the stomach he makes use of a miniature periscope, similar m everything but size to that through which the _ commander of a submarine gets his bearings.. It is (says Science Siftings) a metal tube of- small calibre containing an arrangement of mirrors and lenses, ancKhaving a small electric light at the end. This is pushed down the throat of the patient. The light is turned on. and the instrument is moved about until every part of the inner surface has been examined. The mirrors and lighting arrangement loave enough space in the tube for fine scalpels and forceps and scissors to bo passed down through it. Thus the surgeon is able sometimes to perform delicate operations through the tube and without cutting into the patient's, abdomen. To the outer end of the instrument rubber bulbs are attached, and these are used for various purposes, according to the needs of the case.
