Abstract
No vit. C is present in the fresh hen''s egg, though some is present even after only 4 days'' incubation. The amt. present in embryo chick liver agrees very well with the value given by Hart et al. for livers of chickens kept for a long time on a scorbutic ration. Aqueous solutions of vit. C injected into the hen''s egg apparently produce no change in the growth-rate of the embryo.
