In discussing the chemical triumphs to be recorded in connection with the investigation of the organs of internal secretion, reference was recently made7 to the work of a few prominent investigators in the attempt to isolate the "active principle" in chemically pure form. Our attention has properly been called to the fact that few have attained success in this field without the help afforded by pioneers who paved the way through preliminary efforts, however crude these may have been. We build on the experience of the past. This is true in most branches of science. Sometimes a number of investigators working in an essentially independent manner arrive at the same goal almost simultaneously. Through chance announcement, though usually through some striking cogency or excellence of demonstration, the contribution of one person sometimes tends to be emphasized with the apparent disregard of others whose merits are by no means negligible.
