The average power of pressure on the Mathieu dynamometer is,for an adult, forty to fifty kilograms for the right band, and threeto five kilograms less for the left. A woman bas about two-thirdsof the power of a man. I have bad constructed an apparatus bywhich the strength of the leg push, , of the ex-tensors of the leg and foot, and the extensors of thethigh is tested. Dr. W. Kraus has devised asimpler instrument. The anterior tibial and calfmuscles can also be tested by means of an instru-ment called the pedodynamometer devisedby the late Dr. William E. f ■m
