ABSTRACT A study was made of the changes in volume of the pituitary glands of adult female goats surviving for many weeks after pituitary stalk section. The mean volume of the whole gland was about one-third of that found in control goats of similar sex and age. Pars distalis shrank to one-fifth of the volume of the normal lobe. This shrinkage was due largely to contraction of the scar replacing the original massive infarct, but partly also to shrinkage of the surviving parenchymal cells. The infundibular process also showed a severe reduction in size. By contrast pars intermedia underwent a substantial hypertrophy.
