![These recommendations arc marked “ C.U.D.” in the Extra Pharma- copoeia. Tincture of Strophanthus U.S.P. is increased from 5 to 10 ]>cr cent, strength. Extract of Opium is increased from 18 to 20 per cent, (hut the powdered opium is stronger than the B.P. powder . Jpecac'ianhahas 2 per cent, alkaloids. Tincture of Cantharides is increased from 5 to 10 per cent. Tincture of Digitalis is reduced to 10 per cent., and Tincture of Hyoseyamns is also reduced to 10 per cent. Tincture of Aconite has been reduced from 35 per cent, to practically 10 per cent. Similarly, that of Yeratrum from 40 per cent, to 10 per cent. The object in view in the U S.P. has been to make tinctures of potent drugs a uniform 10 per cent, strength, and the other tinctures 20 per cent. Specific Gravities and Solubilities in the U.S.P. are now determined at 25° C., this being more sat s aetory for the TJ.S. than the old temperature 15° C. Where standards for purity arc given, it is not allowable to exceed 3 per cent, of moisture in non hygroscopic crystalline chemicals. All Hygroscopic Salts arc to he dispensed in a state of sensible dryness. Purity Standards for Efflorescent Salts refer to the uneffloresced crystals which alone should he dispensed. Synonyms have, for the most part, been omitted from the text, but they are given in small type in the index under the official Latin names, and in their alphabetical positions for reference. Synthetic Preparations added in this revision are represented (mostly under their chemical names) by Antipyrine, Phenacetine (Acct- pheuetidinum), Saccharin (Benzosulphinidum), Bromoform, Choralamid (Cho alformamidum), Duotal (GuaiacoLs Carbonas), Urotropin (Hexamethy- lenamina), Iodol, Methylene Blue (Methylthioninse Hydrochloridum,) Trional (Sulphonethylmethanum), Sulphonal (Sulphonmethanum), Aristol (Tbymolis Iodidum). Serum Anfcidiphthericum is an important addition to the Pharmacopoeia decided upon after considerable investigation by a special committee of bacteriologists. Organotherapy is represented by the addition of Glandulse Thyroideae Siccae and Glandulae Suprarenales Siccae. Fluidextracta now represent the Extracta Fluida of the 1890 U.S.P. Those added in this edition and those in which there has been alteration by standardisation or n ethod of manufacture arc dealt with in the following pages, whilst the Extracta Liquida omitted are also indicated- It was thought desira le by the Committee of Revision to separate by this new nomenclature the fluidextraets from the extracts, so as to prevent confusion. Glycerin has been om-tted in Fluidextract of Krameria and of Itubus. That of Sanguinaria is now an acetic one, containing no alcohol. In that of Senega, Potash Solution replaces Ammonia, and in that of Tarax- acum, Sodium Hydroxide is employed. Doses of comparatively potent substances are given where they differ from the B.P. ones.
