    are definite, double salts. In botanical nomenclature, the rules adopted, in 1892, by the Botanical Club of the American Association for the Advancement of Science have been adopted. The rules are as follows : “ 1. In nomenclature, the Paris Code of 1867 shall be followed, except where it conflicts with the following: “ I. The Law of Priority.—Priority of publication is to be regarded as the fundamental principle of botanical nomenclature. “ 2. Beginning of Botanical Nomenclature.—The botanical nomencla- ture genera and species is to begin with the publication of the first edition of Linnaeus’ Species Plantarum, in 1753. “ 3. Stability of Specific Names.—In the transfer of a species to a genus other than the one under which it was first published, the original specific name is to be retained, unless it is identical with the generic name, or with a specific name previously used in that genus. “4. Homonyms.—The publication of a generic name or of a binomial invalidates the use of the same name for any subsequently published genus, or species, respectively. “ 5. Publication of Genera.—Publication of a genus consists only (1) in the distribution of a printed description of the genus named ; or (2) in the publication of the name of the genus, and the citation of one or more previously published species as examples or types of the genus, with or without a diagnosis. “6. Publication of Species.—Publication of a species consists only (1) in the distribution of a printed description of the species named ; or (2) in the publication of a binomial, with reference to a previously published species as a type. “ 7. Similar Generic Names.—Similar generic names are not to be rejected on account of slight differences, except in spelling of the same word; for example, Agios and Apium are to be retained, but of Epidend- rum and Epidendron, Asterocarpus and Astrocarpus, the latter is to be rejected. “8. Citation of Authorities.—In the case of a species which has been transferred from one genus to another, the original author must always be cited in parentheses, followed by the author of the new binomial “II. The limitations of genera given in Bcntham and Hooker’s Genera Plantarum shall be followed, except where an obvious error is involved. “ III. In species limitations those authors should be followed whose views appear to us correct.” Pharmaceutical Classes of Remedies. ACIDS. Two degrees of relative concentration are usually recognized, and in one case (acetic acid) there are three. The dilute acids are all of uniform strength,—one-tenth acid and nine-tenths water,—except dilute nitro- hydrochloric, which contains only 7 per cent., and dilute acetic, 6 per cent., while aromatic sulphuric acid contains 20 per cent, of the official acid; dilute hydrocyanic acid contains only 2 per cent, of absolute hydrocyanic acid. The official Acids are :—
