A t the t h e the I)o& \viis published it \vns not :I nutionti1 lcgul st:indard, Irut I~ec*atiieso subsequently, with the pussnge of the Pood t i n t 1 Drugs Act. Tlic need o f riictliotls was fornirrly not so grwt, titid \ \ l i e i ~ii rdiitiivly siniple test SUCII ns a volumetric or ; i n eiisy gr:ivinietric nietlicid could not be found, none nt ti11 \ + .

The ideii w i s , also to employ tests rcclriiriirp tlic riiiniriiuni iif apparatus and generiil equipmcnt, on tlir iissuiiiption, it is said, tlint retnil druggists :ire the principl iiscrs of the tests. So niurh for tlie prcuvtt Iili:iriiincnl~oeiii-tlic I:. S. 1’. 8th rCvi4in. ’The hook hiis ci1re:idy been printed nntl clistril~tited, has I I ~ C W r e v i d cind corrected by supplt.nantnry circuI:irs, and has nearly served out its time. But w l i i i t of tlic next revision, tlie ninth, the convention for which iiiccts in JIiiy next i How shall tlie clucstion of purity reqtiircnicnts in ttwis ( I f per cent., nnd niethods of assaying be Iiantllcd? .\re we again to till tlie pages with tests for chlorides, etc., m t l omit the rcnlly iniportnnt and mitre difficult nirtliods o f asaiy? Are w e again to confine oursclves to easy volumetric or gravimetric determinations when there are better and inore suit:il)le. though less easy ones, a t liand? Are we phariiiacctitical cheinists willing to be tleiiierl tlie privilege of riiaking use of the latest cidvanc*esin analyticd chemistry? bliist we forego tlie pleasure of usinK the riiodern oxidizers such as stnliiim peroxide and the persii~plvates? Do we not know the remarkable acivmccs that hiive been innrie in electro-analysis? C m we close our eyes for another ten years and bring out a ne\v pliarnincopoein, ignnring a11 these advantages a t our servicr, and all for the sake of keeping things siniple? It dtwrs not seem possible to me. I n our next ph:irniaco~mia we need modern niethtwfs of analysis. Or a t least we sliould accord ourselves the privilegc of using such nletlids. To hcorporiite full quantitative niethcxis o f determining gold, mercury, zinc, antimony, and all the others, would enlarge the honk very materially, arid this is possibly objectionable. For the phartii:icop(xiu to refer the chemist to sonic standard text-book for methods of nniilysis would hardly be justifiable or desirable. I suggest therefore that the Committee of Revision of the Pherniaco~weiafollow the example of the Department of Agriculture in lt’ashington. As-all know this departnient accepts or adopts the methods o f ?analysis of the Association of Official Agricultural Chemists. I k t the Coniniittee of Revision adopt a s their methods of analysis the rncthrds of the American Chemical Society. And it will k an excellent beginning for this the new Division of Pharniaceutical Chemistry to investigate, and if possible agree upon some or a few of the methods of analysis now entirely omitted from and so much needed in the United States Pharmacopnein. Possibly the methods thus worked out and approved by the American Cheniical Society could be made sufficiently attractive to tempt the Cnmmittee of Revision to use or refer to them. I therefore offer the suggestinn that this Division of Pharmaceutical Chemistry take u p the investigation of methods of analysis of pharmacopoeial articles with the idea ofwlccting what maybe termed shndard mctthods of nnnlysia
