ALCOHOL AS A MEDICINE.
 

"These were made by extracting the principles of the drugs in the usual way except that instead of alcohol a mixture of glycerine and water was used in the proportion of one-fourth to one-third part of glycerine, and about five per cent, of acetic acid. These made very elegant preparations, and in the majority of cases appeared to have just the same, and just as great physiological action. Subsequently the ordinary tinctures were distilled, and the extracts thus obtained dissolved in the above menstruum, as far as was possible, in most cases the residuum being found to be inert.

"Gum resins and essential oils were found to be insoluble in this menstruum, and hence such drugs have been given in the form of pill, powder or mixture. Such tinctures are those of assafœtida, benzoin, cannabis indica, cantharides, castor, cubebs, lavender, myrrh, pyrethrum, sumbul, tolu and ginger. Out of 62 tinctures it was found that 46 made good preparations, and 16 did not.

"These were employed for several years. But for some time past, somewhat more reliable preparations have been made for us which contain all the constituents of the alcoholic tinctures without the alcohol. They are for the most part made by taking standardized tinctures, mixing with them sugar of milk, and distilling off the alcohol. The alcoholic extract remains behind in a finely divided condition mingled with sugar of milk. This is broken up, pulverized and compressed into tabloids of a definite dose, which can be taken either in that form or rubbed up and dissolved or suspended in gum water.

"The following have been made up in this form: aconite, belladonna, camph. co., cannabis indica, capsicum, cinchon. co., and cinchon. simpl., digitalis, gelseminum, hyosciamus, nux vomica, opium, strophanthus, ginger and Warburg. Other tinctures will be gradually added to this list.

"As external liniments those commonly used are the linimentum terebinthinæ and the linimentum terebinthinæ aceticum,
