Cuart 2. Lot 959. Even after practically complete suspension of yd during 7 weeks, 
on a mixture of wheat, maize, rolled oats, and butter fat, three of these animals wore able to: 
resume growth at once at a rapid rate, when both sodium chloride and calcium carbonate were 
added to the diet (compare Chart 1, Lots 970, 971, and 714). What is true of this mixture 
of seeds is true likewise of still more complex mixtures of seeds (compare Lot 715, Chart 6, 
and Lots 930 and 713, Chart 7). 
Lot 714 B. It has been shown that the wheat, maize, and oat kernels are too poor in the 
fat-soluble A to maintain normal health in animals over long periods (3). Stunting and xero- 
phthalmia being the most prominent sequele of this type of specific starvation (11). The ad- 
dition of a liberal amount of butter fat (fat-soluble A), after a period of stunting, exerts no 
influence upon the ability of the animals to grow. The first limiting factor is the inorganic 
content of the food mixture (compare Lots 970, 971, 714, Chart 1, and Lot 959, Chart 2, re- 
spectively).
