Abstract
The estimation of vitamin C in the urine has recently been undertaken on a fairly large scale on patients suffering from physical disturbances. Harris (1) and his co-workers investigated 74 hospital patients at Cambridge, and found that 62 (84%) excreted less than the minimum standard, or 13 mgrm. per day. Excluding 19 on special diets, 43 excreted less than 13 mgrm. per day, and the average excretion of 55 was 10 mgrm. per day.
