Excerpt from The Journal of Biological Chemistry, 1917, Vol. 30 The accompanying table gives the result of the analyses for calcium of fifty-four samples of human blood, determinations of the total non-coagulable nitrogen also being done on the pathological cases. It is hoped that these figures may help to establish a base line for further study of the metabolism of this metal. The chief point brought out seems to be that the calcium varies but little in a great majority of subjects. Even in cases of advanced uremia, where the total nitrogen was extremely high, the calcium was not increased. On the other hand, the hemophiliac and the case of purpura hemorrhagica were not lower than what we may regard as normal. The average for the males, with the exception of No. 36, was 6.1 mg. of calcium per 100 cc. of blood; while that for females was 7.1, a difference sufficiently great to stimulate further investigation. In No. 36 there seems to be no reason for the extremely low figure shown. Duplicate determinations were of course performed and there is no doubt that this represents the correct calcium content. Unfortunately, as the patient soon left the hospital, a second specimen could not be obtained. No. 8, on the other hand, was taken from a healthy young woman whose history gives us no clue to the explanation of the high result - 9.6 mg. per 100 cc. Determination of calcium was carried out according to the new method of the author,1 while the total nitrogens were done by the direct Nesslerization process of Folin and Denis.
