The inorganic constituents of the blood were determined while investigating certain phases of kidney disease in children. The material consisted of twelve cases seen in the wards and in the outpatient department. In three of these, determinations were made at various intervals so the figures in different stages of the disease could be compared. There were eight cases of chronic nephrosis, three cases of hemorrhagic glomerular nephritis and one case of nephritis with hypertension.1
In five cases whole blood was used and in seven, blood serum only.2 In a case of nephritis with hypertension there was marked nitrogen retention. In the other cases there was either a moderate or no nitrogen retention.
Calcium.—There was no great variation of the blood calcium from normal figures in any of the cases. In those in which a lowered serum protein was evident, there was a slight decrease in the calcium
