Liver Extracts Everywhere

Three years ago George Richards Minot and William Parry Murphy, Harvard medical men, discovered that liver eaten regularly and in great quantities overcame pernicious anemia. Later their colleague Edwin Joseph Cohn developed an extract to replace bulk liver. To Eli Lilly & Co., Indianapolis manufacturing druggists, the Harvard men gave the commercial monopoly because methods of manufacture were too delicate for novices to handle. Last year other pharmaceutical houses, in the U. S. and abroad, studied the preparations under Harvard instruction. So last week the Harvard Committee on pernicious anemia announced that good liver extracts were available almost everywhere, but that "the most rigid adherence to the recognized methods of preparation must be enjoined. . . ."
