Purified Insulin

Dr. John J. Abel, of Johns Hopkins University, published last week an article, Researches on Insulin in a technical journal. He told of purifying and concentrating insulin so that it is several times as effective as the common product, held out hope of obtaining perfectly pure insulin, of learning its chemical constituents (he is inclined to believe it is a sulphur compound) with the possibility of eventually making it synthetically and also ot discovering a contributing cause of diabetes mellitus in the absence of certain sulphur compounds from the diet.
