In adults, a dose of 300,000 units "gave disappointing results and was discontinued." With a dose of 600,000 units, a detectable serum penicillin level was found within three hours in 67 of 68 assays, and in six patients a level of 0.5 unit or more per milliliter was obtained. After five or six hours, 37 of 59 persons still had levels of 0.06 unit or more per milliliter. The results in children were more satisfactory.
