DISCUSSION. 
Inspection of the tables shows that C. G., the younger child, 
responded promptly to the high fat diet with a marked increase 
in nitrogen, minerals, ammonia, titratable acid, and creatine. 
During the preliminary normal period he excreted the equiva- 
lent of 5,759 cc. of mineral acid and 5,808 ce. of base; that is, 49 
cc. of base served for the neutralization of organic acid. The 
titratable acidity, 380 cc., plus 49 cc. indicates the approximate 
organic acid excretion (429 cc.). During the period of high fat
