Examination showed that the suppositories contain about 0.08 per cent. iodin, or 1.2 per cent. of the amount claimed; 0.28 per cent. sulphur, or 16.3 per cent. of what is claimed; 0.71 per cent. bismuth, or 19 per cent. of what is claimed; and zinc equivalent to 16.5 per cent. zinc oxid, or about 100 per cent. of claim.
From the standpoint of the iodin content alone, assuming that all of the iodin found is present in the form of “anusol,” the results of the examination of the product (as found on the American market) verifies, for all practical purposes, Suyver’s statement that “anusol suppositories contain no anusol,” for the quantity of iodin present is so minute (about 1⁄82 of that required by the formula) as to be unworthy of serious consideration. The presence of sulphid in appreciable amounts was demonstrated showing that the sulphur is present, at least in part, in the form of sulphid and not as sulphonate as is claimed. In a measure, too, this is in accord with the findings of Suyver, who concluded that, in the product which he examined, the bismuth was present in the form of sulphid. The proportions of sulphur and of bismuth (respectively about 1⁄6 and 1⁄5 of the required amounts) indicate still further that the product is not all that it is claimed to be.
A specimen submitted by Schering & Glatz to the Council two years ago contained 0.99 per cent. iodin, or 1.3 per cent. of the amount claimed; 0.23 per cent. sulphur, or 13.4 per cent. of the claimed amount; and 0.52 per cent. bismuth, or 14 per cent. of what is claimed by the formula. Since the above determinations were made another specimen of Anusol Hemorrhoidal Suppositories was received from Schering & Glatz, July 16, 1909. This sample was found to contain about: 0.075 per cent. iodin, or 1.1 per cent. of the amount required by the formula; 0.265 per cent. of sulphur, or 15.5 per cent. of the requirement and 0.88 per cent. bismuth, or 23.7 per cent. of the required amount. It will thus be seen that the composition of the oldest specimen and also that of the specimen recently sent, corresponds in a general way to that of the one first examined.
Whether judgment be based on the determination of the bismuth, the sulphur or the iodin, the results just given clearly show that the claims made concerning the composition of “Anusol Hemorrhoidal Suppositories” are not substantiated by the facts.—(From The Journal A. M. A., Oct. 2, 1909.)
AROMATIC DIGESTIVE TABLETS

It has been amply demonstrated[91] that pepsin and pancreatin, when in solution, mutually destroy each other; if the solution be acid, the pepsin destroys the pancreatin; if alkaline, the pancreatin destroys the pepsin. By using the characteristic effect of pepsin on proteids in acid medium and that of pancreatin on proteids and starches in an alkaline solution it can readily be demonstrated that commercial liquid preparations labeled as containing both of these ferments actually contain only one ferment. They are misbranded.
