Instantaneous Skiagraphy. Our methods of taking skia-graphs are becoming so perfected that we find absolutelyno necessity of subjecting our patients to unnecessary dangerby long exposures. Under proper conditions we can takepictures practically instantaneously, the length of timedepending largely upon the size of the apparatus employed;whether it is coil or static, upon the degree of vacuum of thetube, and upon the thickness of the part to be photographed.
