The use of thymus extract in the attempt to modify the oxytocic of posterior pituitary injection is by no means new.

On this basis it was claimed that Thymophysin could be used with safety to stimulate weak pains in the first stage of labor and to shorten the duration of the second stage. In the publication1 in which this preparation was presented there was only the most limited evidence for such a modification of the action of posterior pituitary injection by thymus extract.

A thorough pharmacologic study of this preparation, and of the effect of thymus extract on the pressor and oxytocic actions of posterior pituitary injection was made by
