five per cent of those measured (see Chart A, No. 1), his length of 

 legs rises to the hundred-per-cent class. The girth of the neck is 

 small, but the low chest measurement is due to its rounded shape.

Its expansive power of seven inches is extraordinary in a chest of 

 that shape. The muscle girths of his arms are exceeded by eighty 

 per cent of young men, while the elbows and wrists show rather 

 heavy bones. The rather small thigh girths will be due partly 

 to their great length. The size of his calves shows about average 

 development to be attributed to bicycling largely but the in- 

 steps are very large, and his photos show a flat foot. The neck 

 and chest are broad, as would be the shoulders if he had better 

 arm muscles. The " bicycle stoop," amounting almost to deform- 

 ity in his case, brings the depth of chest up to the one-hundred- 

 per-cent class. His lung capacity is very good, but he can not 

 pull himself up by his arms more than two and a half times, and 

 one dip on the parallels is the extent of his ability. His pulse is
