Devised by Dr. Russell Reynolds of London, this consists of a very bright fluoroscopic screen on which the direct X-ray picture is thrown and there photographed as it changes by a cine- camera. Since motion picture film must pause 16 times each second to make its record, Dr. Reynolds likewise interrupts his X-ray beam 16 times a second. This reduces the danger in X-ray work of burning a patient or sterilizing him, and therefore enables Dr. Reynolds to make exposures of as long...
With twenty-four students from Harvard and twenty-nine from Yale the honors of the camp were evenly distributed. Harvard topped the lot when Francis X.

Andress, '37, also...
