The arrangement of the matter of the second part is, first, a brief description of the ordinal characters, followed by a list of the drugs belonging to that order, those official in heavy-faced capitals; then the drugs are taken up separately, the official names and synonyms in the important languages presented, the definition, botanical characteristics, sources, related, and similar articles, description of drugs, with the more important characters printed in heavier type, accompanied generally by a picture of the plant and of the drug, gross and structural, important constituents, actions and uses, and a synopsis of the official preparations. The doses of the drugs are given, but not of the preparations, though the strengths of the latter are stated. An unfortunate feature, as in Part I., is the illustrations. They are not at all uniform in effect. While the method followed has given exceptionally good results in some cases, yet in many others they are very unsatisfactory, and this is more particularly true from a scientific than from an artistic point of view. Valuable a contribution as is Part II., there is an evident unfamiliarity with, or disregard of, the commercial aspects of drugs. For instance, the important distinctions between Cassia vera and C. lignea, and the subject of Batavian Cassia, a correct understanding of which is a great aid in the economy of the drug store, are entirely omitted. The distinctions between Coto and Paracoto are not clear, and in the facts concerning commercial occurrence are reversed. Mace is not, as described, a “membrane,” neither does it “invest the kernel.” Moreover, nothing is said about Wild Mace, now so extensively used as an adulterant that it is possible that it constitutes the larger part of commercial Mace. “Reddish brown” boldo leaves are old and worthless. The description of Piper longum is only partly true, according to the variety under consideration, and the individual parts are not “berries.” The part rubbed off from Piper album is not correctly described as an “epidermis.” The important characteristics distinguishing true from false cubebs is not given. Appendix “A” is a valuable contribution on the subject of insects injurious to drugs. Appendix “B” is no less important, it being an account of the contributions of organic chemistry to materia medica. Appendix “C” treats of “Pharmacal Microscopy” in such a fragmentary and superficial way that it will scarcely be found of service to any one in these days. H. H.
