One of the most marked symptoms, while the medicine was continued, was the headache, which was dull and heavy. A dull feeling in the head was never entirely absent, though much relieved by lying down and in the open air; it was forgotten when the mind was occupied, never interfered with study or mental labor, and was always worse on thinking of it, also worse in a warm, especially a very narrow room; this feeling was a dull dragging-down or heavy feeling, more marked in the forehead, close over the eyes, and in the temples, just in front of and a little above the ear; never felt in back part of head and only occasionally on vertex; occasionally it amounted to a decided pain, but seldom.
