but intended rather to mystify the public than to instruct them.
Chemical nomenclature of the present day has gone to the opposite extreme. The ingenious laboratory devisers of synthetic products have developed a nomenclature which it is impossible to use. It explains itself to the initiated, but even for intercommunication between chemists, pharmacists, and physicians words like tetrahydroparamethyloxyquinoline or calcium betanaphthol-alphamonosulphonate insist on being simplified if the substances they describe come into medicinal use; and to do them justice it must be admitted that the inventors of the products are always ready to meet this requirement with a more or less expressive title which can be protected as a trade mark. This forces other manufacturers to devise other distinct names for the same article, so that among the new chemicals which have become popular within the past thirty years there are sometimes a dozen designations for the same substance.
A Pharmaceutical Vocabulary.
The subjoined list of technical terms is limited to the names of pharmaceutical processes, products, and apparatus; and only (as a rule, with some exceptions) of such as are not dealt with in other sections. Many of the terms are obsolete, but are to be met with in old treatises. Occasionally rather more than a bare definition has been thought desirable.
Acetabulum. Originally a vessel used by the Romans for holding vinegar at the table. Then a liquid measure about 2-1/2 oz.
