THE LANCET LONDON:: SATURDAY, APRIL 26, 1941

SALVAGE THE number of men boarded out of the British Army in the first year of the war must be not far short of 100,000. Most of them are young men, under 30 years of age, and they probably suffer for the most part from such conditions as gastric and duodenal ulcer, mental and nervous disorders, rheumatism and rheumatic heart disease, disorders of the chest (including pulmonary tuberculosis), visual defect and foot disabilities. The army has a measure of responsibility for their medical care for 28 days after they are boarded out. Some of the men are awarded pensions, and their subsequent care is in the hands of the Ministry of Pensions, others do not get pensions and on return to civilian life are dependent for their treatment on ordinary civil resources. Most men boarded out of the Army require medical attention from their family doctor after discharge, and many require hospital treatment, which as things are they find more difficult to obtain after they leave the Army. Their treatment should be pressed home to secure the fullest possible degree of stable recovery, partly to prevent chronic invalidity and partly to make the most of them as producers. Reabsorption of these men into civil life does not always proceed smoothly ; probably only about two-thirds of them are in employment six months after discharge, and of these only a minority are working at their old jobs, some of them intermittently. Most of those who find at employment drift, generally the dictate of physical necessity, into some form of light work which entails diminished earnings, or into some dead-end occupation which fails to harness their efforts to the best national

from America. With his flair for doing the right at the just moment Mr. ROOSEVELT has implemented the Red Cross appeal for 1000 male medical graduates from the U.S.A., under the age of 40 for service with the R.A.M.C., under 45 for service with the E.M.S. While retaining their status as American citizens they will become, in Mr. ERNEST BROWN’S phrase, an integral part of our own services. In this connexion the Minister of Health has also spoken of the overruling need that workers, whether in industry or in civil defence, should be restored as soon as possible to active life by skilled supervision and treatment. This is not a task for tired and listless men ; the work of rehabilitation requires all the drive and initiative of an offensive campaign if it is to give results. It is not sufficient to tackle a few isolated groups, like the psychoneurotics : the problem must be approached as a whole, and at once. Its solution may well be the special concern of these New World crusaders.

when the chemist will extract from cultures, perhaps synthesise, clearly defined chemical substances which will confer sound protection against the enteric group of fevers. But these substances are not yet available ; and meanwhile the engrossing saga of antigenic analysis grows. The official medical historian of the Great War was of opinion that, just as the typhoid vaccine then employed was superior to that used in the South African War, in like measure would the vaccine of the future surpass in protective value that of 1918. Between 1925 and 1930 there arose a general recognition of the importance of the somatic 0 agglutinin as a measure of the immunity attained and the relative unimportance of the flagellar H agglutinin. Next, owing to the work of GRINNELLI in the United States in 1932 and PERRY, FINDLAY and BENSTED2 of the R.A.M.C. from 1933 onwards, realisation came that the degree of protection conadvantage. ferred by a vaccine was closely related to the mouseSome remain unemployed because they are unable virulence of the culture used to killing power or to work on account of their physical condition ; some it.
