Fig. 117.—A small portion of the pars anterior of the hypophysis in a normal albino rat (St. ) 10 weeks old, body weight 196 g. This represents the typical adult structure. Most of the cells are of the weakly basophilic type. Several eosinophiles are shown (darker color). X760. Technique, etc. as in Fig. 115.

Cushing and Goetsch ('15) found that: 'in a series of hibernating animals (woodchucks) it has been found that during the dormant period histological changes are apparent in many of the ductless glands. The most notable of these changes occur in the pituitary body, as previously observed by Gemelli. The gland not only diminishes in
