That the leaf vegetables (spinach, lettuce, cabbage, and the like) contain both the vitamines which are essential to growth in the young and to the maintenance of health in the adult seems assured, and gives us further justification for emphasis on green vegetables in the diet of little children, when properly administered--i.e., always cooked, put through a fine sieve, and fed in small quantities.
