The use of cod liver oil as a prophylactic and therapeutic agent in the treatment of patients with rickets, while widespread and generally satisfactory, is being somewhat supplanted by irradiated ergosterol.

A great many of the present observations on the therapeutic and prophylactic value of irradiated ergosterol are based on experiments on laboratory animals, and these reports are made still less accurate in that the dosage of irradiated ergosterol is stated in milligrams, though it is well known that different batches of irradiated ergosterol vary tremendously in the amount of vitamin D contained.

The only satisfactory way to make comparative evaluations of cod liver oil and irradiated ergosterol as antirachitic
