As has already been stated, the history of some cases of affections ofthe pituitary shows symptoms characterising hypopituitarism followingthose characteristic of hyperpituitarism, although of course little or no 1 Gushing has pointed out that these symptoms closely resemble those which occur inanimals about to undergo FIG. 79.—Case of pituitary infantilism.(Byrom Bramwell.)
