BRIEF SYSTEMATIC EXERCISE
had so much vigorous muscular exercise. Every man's chest enlarged decidedly, the smallest gain being a whole inch in the four months; the average being 2⅞ inches, and one, though twenty-four years old, actually gaining 5 inches, or over an inch a month. Every upper arm increased 1 inch, most of them more than that, and one 1¾ inches. As the work was aimed to develop the whole body, there is little doubt that there was a proportional increase in the girth of hips and thigh and calf.
Again, from the Royal Academy at Woolwich, Professor Maclaren took twenty-one youths whose average age was about eighteen, and in the brief period of four months and a half obtained an average advance of 1¾ pounds in weight, of 2½ inches in chest, and of 1 inch on the upper arm; while one fellow, nineteen, and slender at that, gained 8 pounds in weight, and 5¼ inches about the chest! Think what a difference that would make in the chest of any man; and a difference all in the right direction at that!
But the most satisfactory statistics offered were those of two articled pupils, one sixteen, the other twenty. In exactly one year's work the younger grew from 5 feet 2¾ inches in height to 5 feet 4¾ inches. He weighed 108 pounds on his sixteenth birthday; on his seventeenth, 129! At the start his chest girthed 31 inches; twelve months later, just 36! His forearm went up from 8 inches to 10 inches, and his upper arm from 9¼ inches to 11¼.
While the older gained but three-eighths of an inch in height, his weight went up from 153 pounds to 161½, his forearm from 11¼ inches to 12½-—an unusually large forearm for any man—and his upper arm from 11¾ inches to 13¼, while his chest actually made the astonish-
