us that season played a slight rôle; that cases which occurred in the summer tended to be less severe and to be characterized by periods of intermission rarely observed in the winter time. The effect of _climate_ has been accorded a variable place in the etiology of scurvy. Lind believed that a damp, cold climate, such as that of the Low Countries, was conducive to scurvy. On the other hand, since it is realized that diet is the essential element, all other factors have been regarded as of no moment whatsoever. It is difficult to pass judgment on this question, since scurvy is now endemic in such a limited area of the world. It seems quite possible that a damp, cold climate, which depresses the various functions of the body, may exert an influence where the quota of antiscorbutic foodstuff is not quite adequate. Exposure to infection is also greater under such climatic conditions. Economic status has to be considered in connection with infantile scurvy. Numerous writers have drawn attention to the fact that scurvy is seen relatively more frequently among the infants of the well-to-do and the rich than among those of the poor. This curious and paradoxical situation is due to the zealous care which the former receive--the extreme precautions in sterilizing the milk, the addition to the formulas of expensive proprietary foods, the watchfulness to avoid the child's obtaining a chance bit of fruit or vegetable. Since the popularization of commercially-pasteurized milk in the larger municipalities, and the advertising propaganda for the sale of "baby foods" which has extended their use among the masses, this distinction in the social status has been largely obliterated.
