There is commonly elongation of thespinous processes in the cervicodorsal region, and the bodies of thevertebrae are sometimes increased in the anteroposterior diameter. Theribs, clavicles, and sternum are commonly, and the shoulder-bladesoccasionally, enlarged. In the limbs the hypertrophy is most markedtoward the distal extremities. The long bones of the leg and forearm aremost changed at their lower ends. The metacarpals, metatarsals, andphalanges are particularly involved. Histologically, the hypertrophyis a true one, bone being deposited under the thickened periosteum andthe central canal enlarged by the action of osteoblasts. The pituitary gland is enlarged and hypertrophic, filling up the dis
