swollen or infiltrated; the hamstring tendons or the tendo Achilles may be sore and slightly swollen and the site of slight subcutaneous hemorrhages. In some cases there is bone tenderness, pain on percussion of the shins or of the sternum. These signs may be accompanied by, or even precede, hemorrhages in the gums. The diagnosis of rheumatism in infants indicates a lack of knowledge of pediatrics, as this disease is hardly ever encountered in babies under a year and a half of age. It is not always easy to differentiate scurvy from _purpura_. In either disease the gums may be hemorrhagic and swollen, there may be scattered subcutaneous hemorrhages and pains in the limbs. Occasionally, as in a case seen a few years ago, we may be forced to resort to the dietetic test. A close inquiry into the previous diet, however, a history of previous attacks of purpura, the number, and especially the large size, of the subcutaneous hemorrhages, and above all, the diminished number of blood-platelets, should make diagnosis possible. In scurvy the platelets are almost always over 300,000 per cubic millimetre, whereas in purpura they are reduced to less than 200,000. In the army it may be difficult to distinguish scurvy from _beriberi_, especially if they occur side by side as in the recent English campaign in Mesopotamia. There may be a combination of the two diseases, a picture similar to ship-beriberi, regarded by Nocht as a hybrid of these diseases. The diagnosis is rendered more difficult, as at times scurvy is associated with signs of neuritis. We shall have to depend on the involvement of the gums and the hemorrhages in scurvy, and on the hyperæsthesia, paræsthesia, and anæsthesia in beriberi; marked edema points to the latter disease. We have thus far had in mind frank and outspoken cases of scurvy. When we come to consider latent or early cases, the diagnosis is more difficult and may have to be merely tentative. All that need be added, in view of the clinical picture sketched above, is that this condition should not be forgotten in treating adults who have malaise and indefinite "rheumatic" pains and, more particularly, in relation to infants who fail to gain, whose appetite is capricious, whose disposition has become fretful and who have developed the sallow scorbutic complexion. This warning is particularly opportune at present in the United States, where pasteurized milk is fed so extensively to infants, and an antiscorbutic food is not always given. In addition to the symptoms just enumerated, tenderness of the bones, especially of the distal ends of the femora, should be sought for, the urine should be examined carefully for red blood-cells, and perhaps the ends of the long bones radiographed for "the white line" of Fraenkel.
