* The ‘F’ series, and a few others as indicated, were cut by frozen sections 
for study in the fresh condition, or for lipoids, chromaffin reaction, ete. All 
of the remaining glands were embedded and cut in paraffin sections. 
1Rat J 1.7 had just given birth to a (first) litter. The remaining females 
were virgins. 
2 Of the stunted rats (table 1 B), St 80.9 and St 228.4 had practically doubled 
their initial weight during the period of underfeeding. The others were held 
nearly at maintenance (constant body weight) during the period indicated. 
3 Of the rats refed after inanition (table 1 C), all excepting the last three 
were refed after having been held nearly at maintenance from three to about twelve 
weeks of age. S 33.118 and S 33.120 had been held with but slight increase in 
body weight from 21 to 140 and 150 days of age, respectively, and were apparently 
permanently stunted. Rat F 2.3 decreased from 151 grams to 104 grams (loss 
of 31 per cent) during seven days of acute inanition, and was then refed as 
indicated. 
4 The rats subjected to acute inanition (table 1 D) had been given water only 
for periods varying from seven to twelve days, with loss in body weight as indi- 
cated. In four cases the age was unknown. The final body weights are given 
in the table. 
5 The rats with chronic inanition (table 1 E) had been fed gradually decreasing 
amounts of food during a period of about five weeks, with losses in body weight 
as indicated. The final body weights are given. The age was unknown in all 
but the first rat.
