The U.S. steamer Jeannette spent two winters in the Arctic region, and had a single case of scurvy. The U.S. steamer Rodgers was wrecked, and the crew, during its sojourn of six months among the Siberian tribes, suffered severely.
The operations of armies in recent times have not furnished the frightful mortality which, from neglect of sanitary precautions, formerly afflicted them. During the rebellion of 1861-64, out of 807,000 cases there were but 47,000 of scurvy, or 5.8 per cent., with a death-rate of 16 per cent. The French army[1] of 103,770 men during the Crimean struggle had 27,000 cases of scurvy, or 26.0 per cent., with a death-rate of 1.5 per { 169} cent. In the Bulgarian campaign of 1877-78, in an army of 300,000 strong, there were, according to Pirigoff,[2] 87,989 cases of disease, of which 4234, or 4.8 per cent., were frankly-expressed cases of scurvy. This gave a proportion of only 1.4 per cent. of the entire force--a result entirely due to the maintenance, both before and during the war, of a high standard of health.

ETIOLOGY.--Perhaps no disease has furnished a more fertile field for etiological conjectures than scurvy. The father of medicine ranked the disease in one place among those presenting enlarged spleens, and in another with the twisted bowels. He recognized a putrescence of the humors as the underlying factor--a theory that held sway until the beginning of the nineteenth century. The disease attracted wide attention in the seventeenth and eighteenth centuries from its frequent epidemic and endemic occurrence in various parts of the north of Europe, and was believed to be restricted to cold and particularly wet districts--a view that has been long since abandoned with a better knowledge of its habitats. It has been encountered alike in high latitudes north and south, amidst sterile wastes covered with eternal snows and ice, in the temperate zones and in the burning plains of the equatorial regions of America and Africa.
Sex has no predisposing influence, and the fact that more males than females are affected during an epidemic simply indicates that the former are more exposed to the ordinary determining causes. During the siege of Paris, according to the tables of Lasègue and Legroux, there was a very large excess of male cases, and Hayem's figures show only 6 women in 26 cases.
