After reading the Masters Thesis of Mr. Herman L. Karl, the writer became interested in this problem and then took · up the study of the proteolytic activity of normal urine. Mr. Karl worked on the urine of pregnant women. Using gela­tin as a substrate, he hoped to find a difference in prote­olytic activity between the urine of a woman pregnant with a male fetus and the urine of a woman pregnant with a female fetus. His results were not conclusive but suggested that the problem of proteolytic action of urine should be studied under normal conditions.
