In the Russo-Japanese War, after the siege of Port Arthur, it was found that one-half of the garrison of 17,000 men had scurvy.

Although there are certain parts of the world where scurvy is of frequent occurrence, no country has been entirely free from it. As might be expected, it has been particularly prevalent in the North, where vegetation is scanty—in Greenland, Alaska, Russia and the Baltic States. It has likewise prevailed in the tropics when the crops have failed. India has been conspicuous for its large number of epidemics; some years ago scurvy occurred in Arabia among the English troops stationed at Aden, both among the British and the native troops. A recent communication from Aruba, a small island of Dutch Guiana, lying north of Venezuela, illustrates how devastating scurvy still is in some parts of the world. This account tells of 3000 cases of this disease which occurred in 1915 among a population of less than 10,000, owing to the fact that the crops had failed almost entirely during the years 1912, 1913 and 1914.

Fig. 1.—A comparison between the requisitioned quantity (in thousand pound units) of potatoes and other vegetables, and the quantity received per month by an institution in which more than 200 cases of scurvy occurred at the beginning of April, 1916. The total height of column represents the amount needed and requisitioned; the solid black portion the amount received. The number of inmates in the institution remained approximately the same.
The chart illustrates our great dependence on the potato during the winter months. This is due not only to its intrinsic antiscorbutic potency, but, probably quite as much, to the fact that fully twice as many pounds of potatoes are consumed during the winter as of all other vegetables combined. Therefore, if this crop fails or is dehydrated, scurvy will develop in the spring.

It is important for us to realize that we are still dependent on the annual crops for our protection from scurvy; in other words, the world is leading a hand-to-mouth existence in regard to its quota of antiscorbutic food. The truth of this condition has been realized for Ireland, sadly illustrated by numerous epidemics, notably the great epidemic of 1847 reported by Curran. It was demonstrated by the outbreaks of scurvy in Norway in 1904 and 1912, and was brought to the attention of many in the United States in the spring of 1916. In this year our potato crop fell far below the normal, with the result that scurvy appeared in various parts of the United States, especially in institutions (Fig. 1).

The fact that scurvy may occur in any land and climate, even in the garden spots of the world, is strikingly shown by the epidemics reported from Algiers, and the ravages of this disease among the gold seekers in California in 1849. Nothing could be more incongruous than the occurrence of a deficiency disease in this land of plenty.

Outbreaks at Sea.—It is doubtful, however, whether attention would have been focussed so early and so sharply on scurvy, had it not been for the voyages of exploration undertaken in the sixteenth century. These long trips on sailing vessels, where for many months little or no fresh vegetable or animal food was obtainable, were almost as if designed to make a test of the dietetic origin of scurvy. The result was inevitable—five to six months after the ships were out of touch with land, the majority of the crew frequently were incapacitated by this disease, thereby wrecking many an expedition.[2]

The earliest account of the outbreak of scurvy at sea is that of Vasco de Gama, who in 1497 discovered a passage to the East Indies by way of the Cape of Good Hope. The narratives of subsequent explorers, especially those of Cartier and of Drake, are replete with descriptions of the ravages of scurvy. The expedition of Lord Anson in 1740 is always cited as a memorable example of an undertaking which foundered as the result of scurvy. After a cruise of four years, this expedition had lost from this disease more than four out of five of the original number of its crews. In striking contrast to this picture, and to that furnished by the voyages of earlier navigators, is that of Captain Cook, who in 1772 undertook a voyage lasting over three years, sailing from 52° north to 71° south, with a loss of but one of his crew from disease, and that not from scurvy. This remarkable feat, more than any other, centered attention on the feasibility of preventing scurvy, and resulted in measures tending to eradicate it from the navy. Captain Cook attributed the absence of scurvy among his crew to “sweetwort,” an infusion of barley, which he prepared fresh and served liberally. He also prized the antiscorbutic value of sauerkraut.

We find accordingly in 1795, at the instance of Sir Gilbert Blaine, that improvements were introduced in the victualling of the fleet. As the result of a regular ration of lemon juice, the incidence of scurvy fell precipitously. It is due largely to this provision that between the years 1779 and 1813, according to the statistics of Sir Jay Barrow, the morbidity and the mortality in the British Navy was decreased by 75 per cent.
