A dark room and a library completed the laboratory. A large number of university men had voluntarily contributed their services to the success of the work. The object of this laboratory was to furnish material for the laying of a foundation for a scientific sport-physiology and sport-hygiene. From results already obtained in this laboratory, some of which I had an opportunity of examining, I am convinced of the fact that a beginning has at last been made for the scientific elaboration of the proper principles upon which alone the different forms of
