Chemistry ofSynthetic DrugsFIFTH EDITIONP. MAY, D.Sc., F.R.I.C., C.P.A., andMALCOM DYSON, M.A., D.Sc., Ph.D., F.R.I.C.The fifth edition of this work has entailed complete rewritingof all sections. The enormous growth of the subject since thepublication of the fourth edition in 1939 has made the sub-division into chapters according to chemical classificationunworkable. The authors have, therefore, redistributed thematerial according to the biological activity of the drugs ex-cept for a part of the field of chemotherapy where the re-tention of special sections devoted to the consideration ofdyestuffs, sulphonamides, the organo-metallic compoundsand antibiotics assists in clarifying the subject matter.It has been kept in mind that the purpose of this volumeis primarily to discuss the chemistry of synthetic drugs ratherthan their application; hence, discussion of pharmacology islimited to those concepts necessary to account the existenceof the chemical substance as a drug or to facilitate discussionof the relation between structure and activity, which must, inturn, act at least as a guide in the synthesis of new drugs.Ready Autumn 1958 Probably E7 10s.Elementary PracticalOrganic ChemistryCOMPLETE EDITIONA.I. VOGEL, D.Sc.(Lond.), D.I.C., F.R.I.C.This volume is a complete text-book of elementary practicalorganic chemistry. For convenience, it is divided into threeparts: Part I. Small Scale Preparations; Part 11. Qualita-tive Organic Analysis; and Part 111. Quantitative OrganicAnalysis. Part I covers a wide range of preparations, manyof which are new, and utilises commercially-available smallscale apparatus designed by the author. Part I1 is a detailedtreatment of qualitative organic analysis, and contains 43comprehensive tables.Part 111 is an authoritative treatmentof elementary quantitative organic analysis, based largelyon functional groups ; it includes many semimicro determina-tions and also titrations in non-aqueous solvents. 45s.Also available in partsPart I.
