We have made nearly one hundred determinations of the 

 amount of calcium in human blood in the following conditions : 



The figures given are milligrams per 100 c.c. of blood plasma: 

 Acne 12. 1, 10.0, 9.0, 4.5, 6.8, 8.3, 11.3, 10.6, 10.6, 9.8, 8.3, 



9.8, 6.0, 4.9, 11.0, 9.1, 13.2 (16.6, 16.5 repeated), 13.2, 15.9, 12. 1, 

 7.1. 



Furunculosis 6.9 (Dr. J. 1. 1, February 11; 5.9, March 11), 

 9.4, 9.1, 12.0, 8.0, 8.1, 9.8. 



Normal 9.8, 9.4, 7.9, 9.1, 9.3, 8.3, 7.8. 



Diabetes (8.7, January 27; 9.4, January 31; 7.9, February 9; 

 1.1, February 11), 5.0, 10.0, (10.0, January 31; 3.4, February 28), 

 4-8 ,(7.5, February 15; 10.6, February 25; 11.1, March 2), 9.8, 

 8.7, (8.8, February 4; 10.2, February 16), 9.8, (7.2, February 8; 

 6.0, February 11 ; 9.1, March 2), 8.7, (11.0, February 9; 12.8, 

 February 14), 12.5, 10.2, 9.8, 9.1, 11.0, (9.8, February 21; 10.6, 

 February 25), (7.9, February 25; 5.3, March 7), 3.7, 10.0, 8.0, 8.0, 



5.9, 11. 1, 5.3, 16.7; II. 1. 



Hemophilia 5.1; purpura hemorrhagia 7.4; hemiplegia 9.8, 

 9.8; secondary anemia 10.2, 10.2 repeated; nephritis 11. 7; 11. 1, 

 8.4; pulmonary tuberculosis, healed, 14.3; pneumonia 7.8, 9.1, 

 8.4; familial paralysis 8.6, 9.0 repeated. 



The calcium content of the blood of patients with diabetes 

 varied considerably, but with most of them the amounts were 

 normal or below normal and very few were above normal. If such 

 patients were put on a restricted diet the amount of calcium in the 

 blood usually became lower. 



Our chief aim was the determination of the calcium content 

 of the blood of patients with acne and furunculosis. We found 

 that the calcium content of the blood was high in patients with 

 very severe acne who had not been treated, but there were great 

 variations in the amounts of calcium in the blood of acne patients. 

 Four patients with furunculosis had reduced amounts of calcium 

 in the blood. One patient had a very slight amount, i.e., 1. 1 mg. 

 in 100 c.c. of plasma, and one month later, after calcium sulphide 

 therapy, the amount had increased to 5.9 mg. per 100 c.c.
