A complete medical history is kept of every soldier and of every officer from the time he enters the service until he retires, resigns, or dies. A special fireproof building is now being erected which will be devoted exclusively to the care of these records, the preservation of which may be a matter of vital importance fifty years hence. Attached to the Surgeon General's office are three representatives of the Royal Army Medical Corps of Great Britain--Colonel T. H. Goodwin, C. M. G., D. S. O.; Captain John Gilmour of the Royal Army Medical Corps, and Lieut. Col. J. J. Aitken of the Royal Veterinary Corps--and two representatives of the French Army Medical Service--Colonel C. U. Dercle and Major Edouard Rist. These four surgeons act as liaison officers, keeping the Medical Department of the United States Army in touch with the medical services of Great Britain and France. They have made many informing addresses to medical societies all over the United States and have given lectures at the Army Medical School. The immediate staff of the Surgeon General comprises his personal aid, Major M. C. Furbush, M. R. C., of Philadelphia; Colonel George E. Bushnell, M. C., (Medical Corps of the regular army;) Colonel Deane C. Howard, M. C., and Lieut. Col. James V. Van Dusen, M. C. Colonel Bushnell, besides being chief assistant to the Surgeon General, has devoted his special attention to the field in which he has won a unique reputation, that of the treatment of tuberculosis. General Gorgas has enlisted the co-operation of the leading surgeons of the United States as members of the "Rotary Surgical Staff." Among those Medical Reserve Corps officers who have already served for a period at the Surgeon General's office and who are still subject to call from time to time as occasion requires are Major William J. Mayo, former President, and his brother, Major Charles H. Mayo, now President of the American Medical Association. The work of the Surgeon General's office is divided up among seventeen general main divisions. The work of each division is practically independent of the others, though the work of all is co-ordinated. At the head of each of these divisions is an expert in that particular field, usually a medical officer of the regular army, who has around him a group of expert associates, many of whom are drawn from civil life. On April 1, 1917, there were 700 medical officers and about 10,000 enlisted men in the Medical Department of the United States Army. There are now more than 17,000 medical officers in active service and about 150,000 enlisted men in the Medical Department.
