It is in such cases that' an analysis of the blood should yield data of diagnostic and prognostic value.

By a method, which is described elsewhere,1 it is possible to determine acetone, aceto-acetic acid and beta-oxybutyric acid in small amounts of blood drawn directly from a vein. From 2 c.c. to 5 c.c. of blood is sufficient, and the analysis may be carried
