Alum 27 per cent. Zinc sulphate 37 ” Sodium sulphate 8 ” The presence of so large a proportion of mineral salts, of course, leaves very little tenacity in the ointment; particles of the white salts were easily visible to the eye, and the effect of applying the preparation must be practically the same as if the dry salts were rubbed on the skin except that the basis would, of course, act as a lubricant in the rubbing. The last of these preparations was another ointment; the mineral ingredients in this case, however, were in organic combination. This ointment contained copper oleate and aluminium oleate with a basis of lard and a little resin. The proportions of the active ingredients were approximately: Copper oleate 15 per cent. Aluminium oleate 35 ” No alkaloid or other active principle was found. A bottle of lotion for cancer and other affections, obtained in the ordinary way through a dealer, was examined. The label commences with the statement that the lotion “cures cancerous or malignant sores”; then follows a list of other diseases, with the addition, “even cases that have been under the treatment of doctors and at infirmaries for years.” Analysis showed the composition of the lotion to be substantially as follows:— Zinc sulphate 92 grains Carbolic acid (pure phenol) 1·2 oz. Glycerine 1·8 fl. oz. Cochineal solution sufficient to give a deep red colour. Water to 3·3 fl. oz. This quantity is contained in a bottle costing 4s. 6d.; the directions are to add the whole contents to 1½ pints of water, which is to be applied to the diseased parts for about five minutes two or three times a day. Another pretended “cure” for this disease was supplied from an address in Croydon, by a person who described himself as a retired Government analytical chemist. The bottle did not bear an Inland Revenue stamp. The vendor seems to prefer to see and examine the patients. In one such case he was paid 3 guineas, and asked for more, as it was, he said, a complicated case. The directions given were “two tablespoonfuls should be taken three times a day.” Analysis of this liquid showed the presence of ferric chloride, and traces of hydrochloric acid and alcohol, and nothing else except water; the alcohol indicates that the tincture of perchloride of iron, and not the liquor, was employed; determination of the amounts of iron and chlorine present showed that 6 fluid ounces of the mixture contained 5·7 fluid drachms of the tincture.
