The London Fever Hospital is capable of receiving sixty-two patients: in most seasons of the year its wards are full: often there are numerous applications for admission which cannot be received for want of room: there pass through the wards from six to seven hundred patients annually. Two physicians are attached to the institution under whose care the patients are placed alternately in the order in which they are admitted: there is one assistant physician whose duty it is to perform the office of the ordinary physicians when either of these may be incapable of attending, and there is besides a medical officer resident in the house. A history of each case, containing an account of the age, occupation and residence of the patient, together with as full a statement of the symptoms of the disease and of the order of their succession as can be obtained is entered in the journal by the resident medical officer. Each of the ordinary physicians attends daily and enters in his journal a daily report of each of his own cases. The resident medical officer goes round the wards twice a day, namely, early in the morning and late in the evening, to observe if any change requiring attention may have taken place in any patient; and if any such change be observed by the nurses during the interval between these visits they are reported to him by the head nurse without delay; all such events with the modification of treatment they may have required are entered in the journals. Every case that terminates fatally is examined after death, and an account of the morbid appearances is entered in a book kept for the purpose. In this manner, in the progress of years a mass of facts accumulates relating to the statistics, the types, the symptoms, the causes, the diagnosis, the pathology and the treatment of the disease, whether successful or unsuccessful, which both on account of the fullness and accuracy of the record and of the extent of the period it embraces, cannot but be of great value.
