Especially from children's clinics, do we have observations that

 we wish particularly to mention the work of Hess (461), who studied 

 the influence of vitamine C on the growth and weight of infants. To 

 be sure, Byfield, Daniels and Loughlin (I.e. 90) believed that his

 orange juice has a far greater effect than an addition of extra 

 calories, in the form of an increased basal diet. This is evident 

 from the illustration (Fig. 37). It is interesting to note that this
