In 1897 the author treated many cases with desiccatedparathyroids prepared in the Armour Laboratory, but without ap-preciable benefit. Symptoms.—A t3i3ical case of Parkinsons disease presents a moststriking picture. The patient trots into the room with short, reluctantsteps, apparently following his center of gravity. The body is inclinedforward, the neck extended and rigid, the elbows flexed and slightlyabducted, bringing the hands, with their trembling fingers, to the levelof the groins. The face is mask-like, the eyes bright and patient turns bodily, deliberately, and rigidly. He sits down 1 Amer. Jour. Med. Sci., Dec, 1899. - Deut. Zeit. f.
