/l/ For a diet that will supply the nutrients in this column, see table ^0, Diets: Laboratory 

 and Domestic Animals. /2/ Kilocalories. These values represent the approximate amount of food 

 energy available to and capable of use by the animal from the' food absorbed. /5/ For the ado- 

 lescent monkey. /!*/ 0.6 *ig p-carotene = one I. U. /5/ 25 mg has been used with satisfactory re- 

 sults. /6/ A generic term including cyanocobalamin (vitamin B^g) and its hydrogenation product 

 (known variously as B^ga O"" ^12b^ which has approximately the same biological activity. /7/ 

 0.025 **g calciferol = one I.U. /8/ A generic term for alpha-, beta-, delta-, gamma- tocopherols. 

 /9/ Folic acid is not a chemical entity, but a generic term for pteroylglutamlc acid (folacin),

 pantothenic acid, pyridoxine and ribof lavine , or when the animal has first been depleted of 

 folacin. /ll/ A generic term for vitamin Kj^ (2-methyl-5-jihytyl-l,l*-naphthoquinone) , vitamin Kg

 derived from repletion (therapeutic) type experiment. /15/ Exact requirement difficult to de- 

 termine since a deficiency of the vitamin elicits a requirement for an unidentified factor, the 

 "monkey Emti-anemia factor", or greatly increases requirement for folacin. /16/ Includes pyri-
