Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1857 edition. Excerpt: ...them. But the Pharmacopoeiae in common use are full of anomalies and deviations from what seem to be their own principles. For example, according to the laws of the nomenclature of pharmacy, when a pharmaceutic preparation has only a single base, we are told that its name should be made-up of the name of the pharmaceutic form, followed by the name of the base in the genitive case and nothing else. But how does usage conform to this law? We-find Tinctura Opii Acetata as the name of a simple or noncomposite preparation of Opium, because the menstruum is Vinegar twelve fluidounces and ofilciual spirit eight fiuidounces. As appears to me, there is room only for the question whether this preparation is an Acetum Opii or a Tinctura Opii; and as the Vinegar predominates over the ofiicinal Spirit in the menstruum, I think it should rather be called an Acetum. When the menstruum is compound, I should suppose that the predominating ingredient of it should give the name. We find Tinctura Valerianaa Ammoniata applied to a Tincture containing nothing but root of Valerian, as I suppose, because the menstruum is Spiritus Ammoniml 01' Spiritus Hydrogenii Ammidi. We find also Tinctura Guaiaci Ammoniata applied to a Tincture containing nothing but the resin Guaiacum, because, as I suppose, the menstruum is Spiriflls Ammonias or Spiritus Hydrogenii Ammidi. Subsequently We find the same form of language employed to denote quite a lifl'ei-ent thing, viz. to denote the secondary base in a Tincture with two bases, or in other words, a Compound Tincture formerly called an Elixir, as Tinctura Opii Gamphorata, or still more incorrectly Tinctura Camphorm Opiata. Now Camphorata and Opiata KB applied to what is really Tinctura Opii composita, are not analOgous...show more
