Dr. Sargent gave the second of the series of lectures on Physical Training, in the Fogg Museum last evening before a large audience. The lecture was illustrated by three living subjects. Dr. Sargent said in part:

Every part of the human body has been modified and determined by the peculiar function it has been made to perform. The traces of primitive man show a constant struggle with natural forces, a struggle for supremacy which developed all the muscular powers which have been handed down to us.

One of the forces of nature which we are constantly battling against is gravity. Standing erect, holding the head up, all such actions are the overcoming of the force of gravity.

A general physical deterioration of the race is taking place in the large cities and in some parts of the rural districts, which can only be checked and corrected by a return to more simple modes of life or by artificial exercising.

The various systems of muscles of the human body,- the systems on the back: the head and shoulders, the thigh, and the calf muscles-those in front: the foot, the shin, thigh, abdomen and chest,- and the functions of these systems and their methods of action together with the best means of exercising them, were then shown by means of the three models.
