    So that if we take the weight of any individual in pounds—if there is much adipose tissue either deduct it, or take the body weight (if known) before the adipose tissue was added—and multiply this by 3 if life is sedentary, and by 3’5 if life is active, we get the urea required, and if this is again multiplied by 3 we shall get the albumens required to produce it. Example.—A man weighs 160 lbs., but his active weight twenty years ago before he became stout was only 130 lbs., and he is now sedentary ; therefore (130 X 3 X 3) = 1,170 ; and 1,170, or, say 1,200 grains of albumen per day will be required for his proper nutrition and force production. But if such a man leads, or wishes to lead, a decidedly active life, multiply 130 x 3’5 X 3, and 1,365 grains of albumen would be required each day. Old people produce much less urea, say down to 2 grains per lb. per day : thus an old man might only require 130 X 2 X 3 = 780 grains of albumen, and he would also, of course, produce much less force. Children, on the other hand, require much more, and may produce 6-8 and even 10 grains of urea per lb.; thus a child of 35 lbs. may require 35 X 10 X 3 = 1,050 grains of albumen per day. An interesting instance of this came under notice in the case of a boy, aged 10, admitted into the
