important medical subject on a humane and scientific basis. To carry out his plan, Mr. Eddy urged the purchase of a large tract of land near the city and the erection of suitable buildings. He ventured the moderate estimate that the population of the city, then about 110,000, might be doubled by 1836, and quadrupled by 1856. In fact, it was more than doubled in those first twenty years, and sextupled in the second twenty. He was justified, therefore, in believing that the hospital site on lower Broadway would soon be surrounded by a dense population, and quite unsuited for the efficient care of mental diseases. The Governors gave these recommendations immediate and favorable consideration. Various tracts of land, containing in all about seventy-seven acres, and lying on the historic Harlem Heights between what are now Riverside Drive and Columbus Avenue, and 107th and 120th Streets, were subsequently bought by the Society for about $31,000. To aid in the construction and maintenance of the necessary hospital buildings, the Legislature, by an act reciting that there was no other institution in the State where insane patients could be accommodated, and that humanity and the interest of the State required that provision should be made for their care and cure, granted an additional annual appropriation of $10,000 to the Society from 1816 until 1857. The main Hospital, built of brownstone, stood where the massive library of Columbia University now is, and the brick building still standing at the northeast corner of Broadway and 116th Street was the residence of the Medical Superintendent. The only access to this site by land was over what was known as the Bloomingdale Road, running from Broadway and 23d Street through the Bloomingdale district on the North River to 116th Street, and from that fact our institution assumed the name of Bloomingdale Asylum, or, as it is now called, Bloomingdale Hospital. This beautiful elevated site overlooking the Hudson River and the Harlem River was admirably fitted for its purpose. The spacious tract of land, laid out in walks and gardens, an extensive grove of trees, generous playgrounds and ample greenhouses, combined to give the spot unusual beauty and efficiency. This notable work finished, the Governors of the Society issued on May 10, 1821, an "Address to the Public"[1] which marks so great an advance in psychiatry in our country that it deserves study. The national character of the institution was indicated in the opening paragraph, where it announced that the Asylum would be open for the reception of patients from any part of the United States on the first of the following June. Accommodation for 200 patients was provided, and to these new surroundings were removed on that day all the mental cases then under treatment at the New York Hospital on lower Broadway.
