Bernhard,1 in a study of 15 cases of thromboangiitis obliterans, found that the values for the calcium content of the serum and for the cholesterol, the chlorides and the carbon dioxide-combining power of the plasma were within normal limits. Three types of dextrose tolerance curves were found, but only 3 of the 15 patients appeared to have a diminished tolerance for dextrose. Heitz2 studied 27 cases of "obliterating arteritis." Only 2 of these appeared to be characteristic examples of thromboangiitis obliterans (cases 12 and 13). The values for the cholesterol in these cases were 217 and 348 mg. per hundred cubic centimeters of plasma, respectively. Ssokoloff3 found normal values for cholesterol in cases of "spontaneous gangrene" of the extremities.
Silbert, Kornzweig and Friedlander,4 in a study of 69 cases of typical thromboangiitis obliterans, found an average volume of the whole blood of 64.3 cc. for each
