This investigation is one of a series undertaken to determine the response of bone growth in children to an improvement in nutrition. Ossification in the bones of the wrist has been the criterion of bone development; several food supplements have been used to improve nutrition. The effect of the daily addition to an institutional diet of a pint (473 cc.) of milk, plain or irradiated, was described in a previous article.1 The present report concerns the effect of another supplement, cod liver oil.
