experiment with children was accompanied by a similar experiment 

 with rats, with identical results. A second example of this kind is 

 seen in the work of Chick and Dalyell (462), who studied the effect 

 of vitamines particularly on under-nourished children in Vienna. 

 Here, too, the growth-promoting influence of vitamine C may

FIG. 39. TWINS, BOY AND GIRL, WITH SCUKVY 



The girl received at the point C an antiscorbutic in the form of raw milk; 

 later at AC, lemon or turnip juice, with butter or cod liver oil were given. 

 The boy was suffering from subacute scurvy and did not get any antiscorbutic 

 except at the place marked C, when his growth markedly improved; he suffered 

 also from rickets. (Dalyell; courtesy of Brit. Med. J.)

 B. The administration of vitamine to the nursing mother, with 

 effect on the growth of the child, can find its parallel only in the 

 most exact animal experiment. 



Logically, we should begin here with the description of human 

 avitaminoses, like beriberi, scurvy, rickets, osteomalacia, and some
