Table 2. — Weight Changes in Organs of Atrophic Infants 



The number of observations in the individual organs varies in general from 30 to 50, about 

 half of which are original Minnesota cases, the others from scattered sources in the literature 

 (Porter's famine cases not included). The maximum body weight (during life) was available 

 in the Minnesota cases only. The percentage change was estimated for each individual 

 separately, using data compiled by Prof. R. E. Scammon as the norm, and the results averaged 

 for each organ. The figures in parenthesis are for the Minnesota cases alone. Further data 

 for the body weight, etc. in these cases are given by Jackson ('22). Data for some of the 



individuals are given in Table 3
