The “wafers” were really compressed tablets of the ordinary shape, coated with French chalk, and coloured pink externally with eosin. After removing the coating the average weight of the tablets was 2·4 grains; they consisted of substances of “extract” nature, with about 10 per cent. of powdered liquorice. Analysis of the ash showed all the constituents of the ash of extract of _Fucus vesiculosus_ (bladderwrack), and other tests indicated that this extract formed about one-half of the tablet; the other constituent (or constituents) also of “extract” nature, showed no reactions or properties by which it could be identified, and it was probably present merely as excipient. ALLAN’S ANTI-FAT. This substance is supplied by an American “Botanic Medicine Company” from a London office, in bottles containing 6½ fluid ounces, price 6s. 6d. On the wrapper appeared the words: Purely vegetable. Perfectly harmless. Always efficacious. We call special attention to the efficacy of our Anti-Fat in the cure of that distressing complaint—indigestion or dyspepsia. It acts solely upon the food in the stomach, regulating and putting the liver and discharging organs in good working order. A circular was enclosed with the bottle, entitled, “How to get lean without starvation,” from which the following extracts are taken: A very extensive observation has convinced us, since our first circular treatise was issued, that in the majority of cases the Anti-Fat must be taken for from two to three, and, in rare cases, even four weeks before the patient will begin to notice much reduction of flesh, after which the loss goes on rapidly—generally from three to five pounds a week. In some cases the diminution in weight commences from the first two or three days’ use of it. The treatment of obesity has hitherto rested on no sure basis. Through the study of physiological chemistry, a _specific_ has at length been discovered, which, from the name of the discoverer, has been called Allan’s Anti-Fat. Directions: Take two teaspoonfuls of the Anti-Fat in a wineglass full of water or sweet milk before each meal. A small slip was also enclosed headed “CAUTION!!” which stated: The color, as well as the flavor, of the Anti-Fat, varies somewhat with age and exposure to light, but neither in the least impairs its virtues. The temperature of the weather at the time of the manufacture of this remedy has also much to do with its clearness, or transparency, but does not affect its properties.
