Basiphilcells are present in great number. Their cytoplasm is of an open char-acter and vacuolated. It is possible that the swollen cells above mentionedare formed by an alteration of some of these basiphil cells. A large number of the nuclei of the cells of the pars intermedia areenlarged (to about 7-5fJi). The pars nervosa shows comparatively fewdroplets of hyaline substance in its meshes. Effects of Castration in the Male twenty to tifty-seven days after castration considerable changesare found in the pituitary body. The most marked effect is produced by the.

Their description agreesgenerally with that of the swollen cells mentioned as the result of thyroid-ectomy and parathyroidectomy, so far at any rate as the is con-cerned. But many of their nuclei are much larger, and also have a swollenappearance: they measure from 5-7^i to 11/a
