Abstract
DURing the course of an investigation upon the cytology of the parathyroid gland of the mouse, it was observed that in immature animals the cellular differentiation characteristic of the adult did not commence until about fourteen days after birth. It was suggested1 that this stage might (1) mark the beginning of a period of increased mitotic activity associated with differentiation, and (2) be correlated with weaning, which is normally accomplished by the third week. The preliminary data reported here appear to support these suggestions.
