Special attention is called to the explanation of certain tests of quickness which are now being made by Dr. Fitz at the Physiological Laboratory. It may not appear at first thought that these tests have anything about them which is connected with education, physical or mental. Yet they are being made with a view to making clear the relation of physical training to the development of quick and accurate motions and of well balanced bodies. The idea is to find out by comparison what sorts of exercise demand as a pre-requisite the most accurate mental aim and the quickest motor response and also what sorts of exercise develope these to the greatest degree. If the tests made show that with tennis, fencing, boxing and football there go varying degrees of quickness and accuracy, tables can be prepared and statistics made out which will be very interesting and valuable. The tests are along a line parallel and immediately related to those of Dr. Sargent. Dr. Fitz deals with the nervous part of muscular action, while Dr. Sargent tests the body, the agent of the nervous action. As a scientific study these tests are decidedly worthy of attention and the students should take sufficient interest in them to present themselves at the prescribed hours. Men from all branches of athletic training at all will render equal service, for comparisons must include all games of training and skill.
