Recent observations to the effect that autoclaved whey is lacking in some essential component of the vitamin B complex other than thiamine1 cast some doubt on the results of a previous study which appeared to indicate that there is a 60 per cent destruction of thiamine in commercial evaporated milk,2 since in that investigation autoclaved whey was used with the basal ration to supply these other essential constituents. The increased use of evaporated milk, particularly for infant feeding, makes it necessary that the amount of destruction of thiamine be known.

This may account for the fact that many infants 5 or 6 months of age refuse to take sufficient food for normal gains in weight, even though the
