_Rennin_: curdling of milk in moderate excess. _Trypsin_: solution of small shreds of _fresh_ fibrin in neutral and alkaline media, and tryptophan test. _Lipase_: coloration of litmus-milk; exact _color_ controls. All tests were suitably controlled. The responses for pepsin were weak even when compared with those of old pepsin preparations. In the table above, the interrogation points in parentheses (?) refer to results that were obtained after treatment for from twelve to twenty-four hours and indicates that the change was slight at best and of no practical import.--(_From The Journal A. M. A., Oct. 23, 1915, with additions._) IODUM-MILLER AND IOD-IZD-OIL (MILLER’S) Report of the Council on Pharmacy and Chemistry The Council adopted the following report and authorized its publication. W. A. Puckner, Secretary. A referee has submitted to the Council the following report of the Chemical Laboratory of the American Medical Association on Iodum-Miller and Iod-Izd-Oil (Miller’s) (Iodum-Miller Co., Kansas City, Mo.): The unsatisfactory statements made in regard to the composition of Iodum-Miller and the far-reaching therapeutic recommendations for it induced the laboratory to make a chemical examination of the preparation. It claimed more or less directly that the preparation is entirely new and possesses novel characteristics. It is asserted that “Iodum-Miller is made from Soot Iodine, which is our own product. This Soot Iodine is SOLUBLE IN WATER before being combined with its base C.P. Glycerine.” No information regarding “soot iodine” is offered and an inquiry sent to the proprietors by a physician brought only the noncommittal reply that “soot iodine” “is made from Resublime [resublimed?] Iodine by a chemical process which renders it soluble in water before being combined with its base.” Iodum-Miller is said to contain “Active Free Iodine 2.2 grams per 100 c.c., 10. grains per fluid ounce, 1.7% by weight.” “In addition to the active free iodine ... IODUM-MILLER carries a still greater per cent of Iodine in its basic combination....” According to the label, the preparation is “An Iodine for External and Internal use ... 45 drops equals 1 dr. by weight. Each drop equals the per cent. of iodine in 1 gr. potas. iodide.”
