PATHOLOGY OF METABOLISM IN INFANCY 811 



some instances a restriction of water and of mineral salts has resulted 

 in a prompt cure. Elimination of fat from the diet is at times equally suc- 

 cessful as is also elimination of specific proteins to which certain of these 

 infants are sensitive. Although there has been a large mass of clinical 

 literature on the subject of eczema, our knowledge of the true nature of 

 the condition and the changes that are occurring in the metabolism is most 

 fragmentary. Regarding the other manifestations of the so-called "exu- 

 dative diathesis" we know still less.
