IN READING A PRESCRIPTION find the quantity of any ingredient called for, in the left marginal column (dose say gr. 4), and on the same line in the column headed by the number of ounces in the mixture (311) you will find the quantity in each drachm dose (gr.). Of course when the dose is more or less than 31 the result must be proportionately multiplied or divided accordingly. Copyrighted, 189, by P.

This Index has been arranged with the object of enabling instant reference to be made to the mention of every article of the Materia Medica, every drug, official or unofficial, and each preparation, derivative or constituent thereof, which is treated of in the first part of the book, every article, preparation or operation discussed in the pharmaceutical portion, and every disease or other title contained in the therapeutical section. Many of the entries are only made once, but double and even treble entries are made for every item which seemed of sufficient importance to warrant such repetition. INDEX. Salts are each placed but once in the Index, under their English names and the titles of their acid factors, thus, Acetate of Potassium. A basic view of the salts under their basis titles is seen in the section on Materia Medica, but as no such view of the Allyl, Ethyl, Methyl, Propyl and similar compounds exists in the book, these are each indexed twice, under both the acid and basic portions of their names, as Cetyl Palmitate and Palmitate of Cetyl. Plants are indexed under both English and Latin nimes, except where the technical name of the plant corresponds in part with the official drug-title, in which case the one entry serves for both. Thus the entry Conium answers for the plant Conium maculatum, as well as for the official drug; but the drug Nux Vomica and the plant Strychnos Nuxvomica receive separate index entries. Alkaloids are each entered once only and under their chemical termination, ine; their salts following the same rule as other salts. Glucosides and similar principles (except such are acids) are indexed under their chemical termination, in. Preparations are indexed under their Latin names where the reference is to the class, as Infusa, 430; but the several individual preparations are placed under their English titles, thus, Infusion of Digitalis, 204; the reference being to the Infusum Digitalis, page 204. |
