three are connected with city hospitals, and the remainder are operated by private institutions. This voluntary association of private and municipal dispensaries, sharing equal responsibilities and acknowledging equal obligations, is a striking feature of tuberculosis work in New York and presents a unique example of co-operation. The task of standardizing the clinics was a difficult one. One clinic had ten rooms with every convenience. Another had one room and no conveniences. Some clinics made no provision for sputum beyond a cuspidor; others provided gauze or paper napkins when patients entered the room. Two clinics provided no drinking water; two had a metal water cooler in the waiting room; one provided sanitary drinking cups; and another had two enamel drinking cups chained to the wall. Some clinics had sanitary fountains; in others the nurse kept a glass on hand for the patients. Neither was there any uniformity in matters of dress. Nurses and doctors at some clinics wore ordinary street clothes. At other clinics, gowns or aprons, with or without sleeves, were worn. Three clinics occupied separate buildings of their own. Four clinics provided separate waiting-rooms for tuberculous patients. At one dispensary the tuberculous patients had the use of the general waiting room, there being no other clinics held at that time; other clinics made no distinction, tuberculous patients using the general waiting room in company with patients attending other clinics. After studying the conditions existing in the various clinics, it was decided that to belong to the association each clinic must subscribe to and comply with the following regulations: a. Tuberculous patients must be segregated in a separate class. b. Home supervision of all cases by a graduate nurse especially assigned for this purpose must be maintained. c. Each dispensary must serve a certain district, and all cases living outside of this district must be transferred to the clinic serving the district within which they live. Early in the history of the Association objection was made to this last rule by teachers of medicine, who held that it tended to deprive them of teaching material; but they soon fell in line with the other dispensaries when they saw the advantage it afforded them of improving their methods without loss of teaching material, and the further opportunity of securing home supervision. From time to time it has been necessary for the Association to adopt certain methods of procedure in the administration of the various clinics. The general policy of the Association is as follows: (1) Each clinic should arrange for a physician to visit and treat in their homes patients who are too ill to attend clinic, for whom hospital care cannot be provided. (2) Special children's clinics should be established wherever the size of the clinic warrants it.
