medical subjects were treated in so concise and telling a way that they were immediately welcomed by a large class of readers. A chapter on the use of the Alcoholic Lotion in Phthisis Pulmonalis is said to have been the means of saving many lives; another on “the Temper Disease” is most interesting to the student of human nature as well as of medicine. A friend, Mr. Henry Gregory, of Herne Hill, who had much professional and friendly intercourse with Dr. Hall, says of him: “In debate or conversational argument nothing seemed to escape his penetration. His minuteness in bringing out little things which others thought not of, was remarkable; with one little atom, so to speak, a light would shine forth from him so brilliantly that I could only sit and admire his remarkable mental gifts. He was a great man and a genius, and, like all the truly great, made no parade.... He was the educator of the intellect; his domain was pure scientific research. The earnest activity of his mind made him proceed, and every advance he made was a clearing away of error and an establishment of truth.... In emergencies he was both prompt and cautious; when anxious excitement surrounded him, it did not disturb his judgment. In dangerous and difficult cases he was always calm. His deep sense of duty and responsibility was unbending.” There is a universal concurrence of testimony as to his great success in gaining his patients’ confidence; young and old looked with delight for his visits. He would always direct the responsible nurse most precisely, and endeavour by every possible device to secure that his special treatment should be carried out. His searching and pointed questions not unfrequently discovered “hidden seizures,” as he called them, which had been totally unsuspected or uncomprehended by patients or friends. His power of devising a remedy is amusingly illustrated by his prescription to an indolent lady that she was to walk daily to the Serpentine from her home, and dip her finger in it. The desirability of healthy mental occupation, and the encouragement of happiness and pleasing customs generally, were favourite subjects of his injunctions. Sympathy and kindliness shone through his whole manner. A Scotch minister said to him: “You place your soul in the stead of your patient’s soul.” But he abhorred all coaxing and wheedling; he hated cant. He would not lower his own lofty sense of independence by anything approaching to it. One might have supposed so sympathetic a nature would have been compliant; but his spirit and dignity were consistent with and equal to his sympathy. It was but another phase of his noble character that he could attend the poor and the needy middle-class without allowing or causing them to feel the slightest difference between themselves and the rich.
