In mild cases of scurvy neither the color, the alkalinity, nor the coagulability of the blood differs from that of blood in health, though Wood alleges that the clot is loose and cotton-like, and Canstatt that its coagulability, in consequence of the large proportion of saline matters, is diminished. In Busk's cases the separation of the clot and serum was as perfect, and took place as rapidly, as in healthy blood, and in two of them the blood was both buffed and cupped, as it was also in Leven's cases. In two of the most severe of Becquerel's cases the blood coagulated firmly, and in a slight case the clot was dark and loose. The albumen of the blood shows no marked change as regards its quantity. The five analyses of Becquerel and Rodier showed the average amount of organic matters of the serum to be 64.3 parts in 1000, the smallest being 56.2 and the largest 69.2 parts. 1000 parts of the serum of the same cases gave an average of 72.1 parts of organic matter. Frick's single case gave 87.045 parts per 1000, and the average of Busk's was 78.2 parts, while Chotin and Bouvier obtained only 62.3 parts. The last-mentioned writers have recorded a fact in connection with the physical characters of scorbutic blood that deserves notice: the blood in one case did not coagulate at the usual temperature (about 158° F.), but required a temperature some degrees higher for that purpose. The red corpuscles in all the foregoing cases were notably diminished, the largest amount given being 117.078 parts per 1000, while the lowest was 47.8 parts. In Andral's second case the globules had decreased to 44.4 parts per 1000, the lowest amount yet recorded.
