ed in certain crystalline bodies, which can be isolated, and used in minute and convenient forms, and that they can be held in aqueous solutions. Alcohol is no longer needed to hold the active principles of opium, Peruvian bark or other indispensable drugs. As regards the vegetable tonics so called, the best among them is the columbo (Radix columbo) and this readily yields its bitter principle to water, as does quassia, gentian, senna, rhubarb and most other valuable substances. A careful survey of the contents of a well-appointed modern pharmacy leads to the conclusion that there is no one indispensable medicinal preparation which requires alcohol as a free constituent. "The catalogue of modern remedies is almost endless, and many of them hold alcohol in some form; but every intelligent physician knows that 90 per cent. of these alleged remedies have little or no intrinsic value. The nostrums of the quack, the bitters, elixirs, cordials, extracts, etc. nearly all contain alcohol, and this is the ingredient which aids their sale. The whole unclean list might, with advantage to mankind, be thrown to the fishes. "The chemist, more particularly the pharmaceutical chemist, may inquire how he is to conduct his processes without alcohol. It is from the pharmaceutical laboratory we derive some of the most important substances used in medicines and the arts. Among them may be named ether, chloroform and chloral hydrate, three of the most indispensable agents known to science, and the employment of alcohol is essential to their production. Alcohol is a laboratory product; it is a chemical agent which belongs to the laboratory; it is the handmaid of the chemist, and, so long as it exists, should be retained within the walls of the laboratory. In the manufacture of most of the important products in which alcohol is either directly or indirectly used, its production may be made simultaneous with the production of the agent desired. In the manufacture of ether and chloroform, the apparatus for alcohol may be made a part of the devices from which the ultimate agents, ether and chloroform, result. Fermentation and distillation may be conducted at one end, and the anaesthetics received at the other. It is true that in a chemical laboratory alcohol is an agent very convenient in a
