426 REVIEWS INKS : THEIR COMPOSITION AND MANUFACTURE. By C. AINSWORTH MITCHELL, D.Sc., F.I.C. Fourth Edition. Pp. xi + 408. London: Charles Grihn tt Co., Ltd. 1937. Price 12s. 6d. net. This, the fourth edition of the standard and, indeed, so far as the reviewer’s knowledge goes, the only text-book on the subject in the language, bridges L gap of 13 years. The author, pre-eminent in his particular sphere, needs little more introduction to the world of technical industry than he does in his official capicity to readers of THE ANALYST, while his reputation in forensic science in all that appertains to handwriting is international. The chemistry of ink, difficult as it is and at times not a little obscure, hcl- riot developed markedly in the interval since 1924; but what progress has been made is covered by Dr.Mitchell in this edition in a very thorough manner. He has found it necessary to enlarge his work to the extent of some 20 per cent. and, in addition, to rewrite a large portion. The arrangement of the book follows the lines of previous editions. After a comprehensive historical introduction, the work is divided into three sections dealing with writing inks, printing inks, and inks for miscellaneous purposes, respectively. Under Section 1 are considered the chemical nature and treatment of the various raw materials used for writing inks from lcmp black to galls, the composition of finished iron-gall, logwood, vanadium, aniline black, and coloured inks, as well as a comprehensive scheme €or the tech~ical examination of inks, handwriting specimens and the identification of forge:-ies.Section 2 deals with the manufacture and examination of printing inks. ,tnd Section 3 with the miscellaneous materials entering into the compositilxx of copying, marking, safety, sympathetic, typewriter inks and so on. Amongst new matter may be noted references to the use of lignone sulphni--,ites in connection with writing ink, a scheme for the identification of individual con- stituents in inks in the form of writing, and the application of filtered ultra-.& if )let light and of infra-red photography in the elucidation of those problems to which such methods are suited. The British Government Standard Specificatior:s for Writing Inks, revised in 1928, are included for the first time. The avaihble evidence upon the constitution of gallotannin is brought up to date and <tbly reviewed, and there is a Comprehensive list of British patents.It is as difficult to withhold admiration of the encyclopaedic scope cjf the matter and references in this book as it is of the erudition and industry displiiyed in its compilation. Practically nothing that comes to mind has escaped atterition, and it is with rather impish glee that the reviewer, after careful search, asserts that he finds no specific reference to the type of alkaline (ammoniacal) gallotannate- iron ink, said t o find favour in the United States, although the di-ammonium hydroxyferrigallate compound of Silbermann and Ozorovitz receives notice. Nor is there mention of that class of quick-drying writing fluids which depend for their efficiency upon partial destruction of the paper sizing by caustic alk 1.5 or sodium silicate. There is no evidence that lignone sulphonate inks have proved se-rious competitors to iron-gall writing inks (pp. 15 and 175). Apart from the unkttmwn quantity of permanence, the principal failing of this type lies in their liability to contain traces of free sulphurous acid to which suspicion attaches in connt-ction

426 REVIEWS INKS : THEIR COMPOSITION AND MANUFACTURE. By C. AINSWORTH MITCHELL, D.Sc., F.I.C. Fourth Edition. Pp. xi + 408. London: Charles Grihn tt Co., Ltd. 1937. Price 12s. 6d. net. This, the fourth edition of the standard and, indeed, so far as the reviewer’s knowledge goes, the only text-book on the subject in the language, bridges L gap of 13 years. The author, pre-eminent in his particular sphere, needs little more introduction to the world of technical industry than he does in his official capicity to readers of THE ANALYST, while his reputation in forensic science in all that appertains to handwriting is international. The chemistry of ink, difficult as it is and at times not a little obscure, hcl- riot developed markedly in the interval since 1924; but what progress has been made is covered by Dr.Mitchell in this edition in a very thorough manner. He has found it necessary to enlarge his work to the extent of some 20 per cent. and, in addition, to rewrite a large portion. The arrangement of the book follows the lines of previous editions. After a comprehensive historical introduction, the work is divided into three sections dealing with writing inks, printing inks, and inks for miscellaneous purposes, respectively. Under Section 1 are considered the chemical nature and treatment of the various raw materials used for writing inks from lcmp black to galls, the composition of finished iron-gall, logwood, vanadium, aniline black, and coloured inks, as well as a comprehensive scheme €or the tech~ical examination of inks, handwriting specimens and the identification of forge:-ies.Section 2 deals with the manufacture and examination of printing inks. ,tnd Section 3 with the miscellaneous materials entering into the compositilxx of copying, marking, safety, sympathetic, typewriter inks and so on. Amongst new matter may be noted references to the use of lignone sulphni--,ites in connection with writing ink, a scheme for the identification of individual con- stituents in inks in the form of writing, and the application of filtered ultra-.& if )let light and of infra-red photography in the elucidation of those problems to which such methods are suited.

426 REVIEWS INKS : THEIR COMPOSITION AND MANUFACTURE. By C. AINSWORTH MITCHELL, D.Sc., F.I.C. Fourth Edition. Pp. xi + 408. London: Charles Grihn tt Co., Ltd. 1937. Price 12s. 6d. net. This, the fourth edition of the standard and, indeed, so far as the reviewer’s knowledge goes, the only text-book on the subject in the language, bridges L gap of 13 years. The author, pre-eminent in his particular sphere, needs little more introduction to the world of technical industry than he does in his official capicity to readers of THE ANALYST, while his reputation in forensic science in all that appertains to handwriting is international. The chemistry of ink, difficult as it is and at times not a little obscure, hcl- riot developed markedly in the interval since 1924; but what progress has been made is covered by Dr.Mitchell in this edition in a very thorough manner. He has found it necessary to enlarge his work to the extent of some 20 per cent. and, in addition, to rewrite a large portion. The arrangement of the book follows the lines of previous editions. After a comprehensive historical introduction, the work is divided into three sections dealing with writing inks, printing inks, and inks for miscellaneous purposes, respectively. Under Section 1 are considered the chemical nature and treatment of the various raw materials used for writing inks from lcmp black to galls, the composition of finished iron-gall, logwood, vanadium, aniline black, and coloured inks, as well as a comprehensive scheme €or the tech~ical examination of inks, handwriting specimens and the identification of forge:-ies.Section 2 deals with the manufacture and examination of printing inks. ,tnd Section 3 with the miscellaneous materials entering into the compositilxx of copying, marking, safety, sympathetic, typewriter inks and so on. Amongst new matter may be noted references to the use of lignone sulphni--,ites in connection with writing ink, a scheme for the identification of individual con- stituents in inks in the form of writing, and the application of filtered ultra-.& if )let light and of infra-red photography in the elucidation of those problems to which such methods are suited. The British Government Standard Specificatior:s for Writing Inks, revised in 1928, are included for the first time. The avaihble evidence upon the constitution of gallotannin is brought up to date and <tbly reviewed, and there is a Comprehensive list of British patents.It is as difficult to withhold admiration of the encyclopaedic scope cjf the matter and references in this book as it is of the erudition and industry displiiyed in its compilation. Practically nothing that comes to mind has escaped atterition, and it is with rather impish glee that the reviewer, after careful search, asserts that he finds no specific reference to the type of alkaline (ammoniacal) gallotannate- iron ink, said t o find favour in the United States, although the di-ammonium hydroxyferrigallate compound of Silbermann and Ozorovitz receives notice. Nor is there mention of that class of quick-drying writing fluids which depend for their efficiency upon partial destruction of the paper sizing by caustic alk 1.5 or sodium silicate.There is no evidence that lignone sulphonate inks have proved se-rious competitors to iron-gall writing inks (pp. 15 and 175).

REVIEWS 117 Reviews THORPE’S DICTIONARY OF APPLIED CHEMISTRY. By (the late) J . F. THORPE Kt. D.Sc., F.R.S. and M. A. WHITELEY O.B.E. D.Sc. Fourth Edition. 1941. Vol. V. FEH-GLASS. Pp. 609. Price 70s. Also Abridged Index to Vols. I-V. Pp. 19. Price 3s. London Longmans Green & Co. Ltd. 1941. A renowned lexicographer has said that the making of a dictionary was dull work. No doubt it may be so; but not if it is of applied chemistry or a “Thorpe.” Certainly the volume before us is not dull; the advances in our science and particularly in its industrial applications have been so wide and so rapid that to the initiated at least it is absorbingly interesting. Just to take a few major items-alcoholic fermentation finishing textile fabrics ‘fumigation glass-each has its romance each is a tale of achievement of steady progress a t times stimulated by touches of genius such as that of Harden in the study of fermentation.But the busy practising chemist perhaps doesn’t read for interest so much as for an epitome of up-to-date information and references to further sources. He is not disappointed; it seems to the reviewer that the undoubted success of Thorpe’s Dictionary is largely due to the faculty the Editors have of securing articles which so well combine theory and practice that we seldom turn to any volume without obtaining real help. There is in this volume as in the others a nice balance between matters theoretical and practical. This new volume contains some excellent monographs which appear in dictionary form for the first time.Fermentation (Mould) i s one; it is by Dr. Birkinshaw who is well known as a collaborator with Prof. Raistrick and admirably summarises a wide range of work which has become of great national importance for the synthesis of several products. Public Analysts will turn with interest too to Dr. Goldsmith’s articles on Food Preservation and Preservatives. Dr. Goldsmith has ably conned the work of the Foo 118 REVIEWS Investigation Board and original papers in THE ANALYST and in foreign journals so as to notice nearly every topic of importance. The Finishing of Textile Fabrics by Ellis Clayton, and their Fireproofing by Dr. Ramsbottom are pages full of information and thoroughly up to date. To mention the many other equally valuable contributions would extend this review beyond editorial elasticity; but appreciation ought to be accorded to Dr.W. E. S. Turner whose pioneering work on Glass during and since the last war has been of such great industrial value; much of it is summarised in the final articles in this volume. In view of the lack of available copies of later volumes of the earlier edition we hope it may be possible for the remaining volumes of the new edition to be produced sooner than was anticipated and that even a t cost of shortening some topics it will not be neces-sary to produce too many volumes to complete the work. All consultants consult “Thorpe” and all will welcome Volume V. The publishers have done useful service in providing for a modest 3s. a convenient abridged index giving cross references which would have appeared as separate entries had the Dictionary been published as a complete work.It is not however a complete index to the five volumes. H. E. Cox POLAROGRAPHY. By I. M. KOLTHOFF and J. J. LINGANE. Pp. 510 + xvi. New York (Obtainable in the U.K. from H. K. Lewis The polarographic method of chemical analysis was invented about 20 years ago by Professor Heyrovsky in Prague and the polarograph was developed by him and M. Shikata in 1925. Although the literature on the subject is extensive much of it is scattered in foreign journals; this the first complete monograph on the subject in English is therefore to be welcomed more especially as analysts in this country are at present displaying so much interest in the technique. Briefly the essence of the method consists in the interpretation of the current-voltage curves resulting from the electrolysis of the test solution in a cell consisting of a dropping mercury cathode which becomes subject to concentration polarisation and a relatively large anode usually a pool of mercury.In favourable circumstances the nature and con-centration of the electro-reducible or electro-oxidisable substances present in solution can be determined from the characteristics of the current-voltage curves. In more favourable circumstances it is possible simultaneously to detect and determine five or six different substances. The method is suitable for small concentrations to molar and the analysis can be carried out on a very small volume of solution. These are substantial claims. The first part of the book gives an outline of the general principles of polarography and of its applications.Part 11 consisting of 200 pages and 13 chapters is devoted to a dis-cussion of the theoretical principles involved. The analyst will find much of this heavy going and may be inclined to the view that the circumstances will have to be indeed favourable for the claims outlined in the introduction to be realised. A few quotations will illustrate this point. “When the half-wave potentials of two substances are close together so that a well defined diffusion current of the more easily reducible substance is not obtained before the reduction of the second substance starts the measurement of both diffusion currents becomes difficult. . . . The simple fact is that when the diffusion current is not well defined it is impossible to obtain an accurate measure of it and when it is well defined the direct method of correcting for the residual current is the most correct in principle and the most satisfactory in practice.It must be admitted however that empirical methods of approximating it may be of analytical value in certain cases.” Chapter VIII deals with the difficult subject of maxima for the occurrence of which it is not yet possible to account by any single theory. The various methods in use for their elimination or suppression are described. I t will be realised that the treatment of this the theoretical section is detailed and critical and to quote the Authors “goes beyond the immediate needs of the practical analytical chemist but we feel that it is justified in view of the fact that the usefulness of the polarographic method extends beyond the realm of applied analytical chemistry and is proving to be a powerful tool in the solution of more abstract problems in chemistry and related fields.” Interscience Publishers Inc.1941. R. Co. Ltd. London.) Price $6.00 (36s.) REVIEWS 119 Part I11 deals with apparatus and technique Parts IV and V with inorganic and organic polarography respectively. In Chapter 25 on the Analysis of Technical Materials, procedures that have been developed for typical commercial materials are discussed but the whole occupies only 13 pages! The metallurgical analyst would find most to criticise here. One example will suffice-Molybdenum is separated from steel by precipitation as MoS, and roasted to MOO, which is dissolved in sulphuric acid; only then is the solution polarographed.The biological applications described in Part VI appear most promising for here samples are necessarily small and existing methods inadequate. The differentiation and deter-mination of traces of certain proteins have been accomplished and there are indications that the method may be useful for the determination of riboflavin in the presence of the other members of the vitamin B Group to give two examples. Part VII discusses Voltammetry (a term considered by the authors to be more logical than polarography) with Platinum Micro-elec t rodes and finally Amperome t ric Titrat ions. This last is perhaps of the most immediate practical interest to the analyst.In ampero-metric. titrations “the current which passes through the titration cell between an indicator electrode and an appropriate depolarised reference electrode a t a suitable applied E.M.F. is measured as a function of the volume’of a suitable titrating solution.” Polarography is fashionable a t present and it may not be out of place therefore to attempt a review of the position as it affects the analyst. Here is a new technique-attractive founded on sound theoretical principles. It has come to stay but its usefulness will not be increased either by those who ignore it or by those who are too enthusiastic in their praise. The potential value of the polarograph is great but it will have to take its natural place among the other excellent physical tools-the spectrograph the X-ray diffraction camera the photoelectric absorptiometer potentiometric titration-with which the chemist is now provided.Nor will it be possible to overlook the increase in speed and precision in classical methods of analysis.that is constantly going on. Its use for any particular determination must depend on its having real advantages over existing methods. For the larger and wealthier organisations this will be the natural situation but where the choice of tools is conditioned by expense the polarograph will not readily oust cheaper and satisfactory methods. There is always a danger of the analyst losing perspective, overlooking the importance of the result of the analysis in his enthusiasm for the method by which it is obtained. This applies to those who use burettes as well as to those who prefer electrical gadgets but with our radio-minded generation the danger may be greater with the second class.Under the best conditions the accuracy of the polarographic method is said to be about f 2 per cent in the concentration range from lo4 to 5 per cent. between 10-5 and 10-4 molar. A knowledge of this together with the other factors in-volved should help to assess its value in any particular application. One learns that certain metallurgical control analyses are already being carried out in this country by polarography. There is something to be said for abolishing the drudgery of routine control analysis; those who believe it is soul-destroying may prefer to carry out the destruction by an electrical method; relative speeds of despatch (of the results of analyses) should be greater.For those who believe that on occasion great chemists can from routine testers grow the new methods may not be adopted without a tear. The authors are probably aware of all this but have quite rightly been concerned with the critical presentation of all. that was known and believed about polarography up to the end of 1940. In this they have succeeded magnificently and they are to be congratulated on the production of a most fascinating book. The binding and printing alike are excellent. molar and about R. C. CHIRNSIDE PHYSIOLOGY FOR PHARMACEUTICAL STUDENTS. By H. H. BARBER B.Sc. Ph.D. Second Ed. Pp. x + 526; 164 illustrations. London Bailliere Tindall & Cox. 1941. Price 15s.As the body of scientific knowledge continuously expands increase of specialisation is inevitable; different branches of a subject are taught by specialists in that particular branches and the student may at first fail to perceive the fundamental relationship between the various aspects of a single science or its relations with other sciences. For the elemen-tary student of physiology a general textbook embracing all branches of the subject suc 120 PUBLICATIONS RECEIVED as were once described under the headings chemical and experimental physiology and histology as well as general physiology serves as a ground-work for the subsequent use of more advanced works. At the same time some knowledge of physiology may be an advantage or even an essential item in the training of students of other sciences; the subject is now required in the final examinations of the Pharmaceutical Society of Great Britain and in the examinations for degrees in pharmacy of several English Universities.Dr. Barber’s book is designed for the student of pharmaceutics. The necessity for a second edition within 4 years of the first indicates that it has found a definite sphere of usefulness within its chosen field and has also enabled the author to revise the text incorporating recent knowledge and adding upwards of 30 additional illustrations. Dr. Barber has written an introduction to physiology in the widest sense; it includes exercises in histology experimental physiology and physiological chemistry. It is there-fore a book for the elementary student who is required to obtain a general knowledge of his subject and should serve as an adequate textbook for pharmaceutical students.For medical students the practical sections are too narrow in their scope consisting chiefly of analytical work. The author may be congratulated on his success in keeping the book up to date since for a general textbook of this nature wide acquaintance with the subject is necessary. In one or two subjects however advance in knowledge has been possibly too swift for the author to incorporate it before the book went to press. For instance, there is now an international unit of activity and an international standard for vitamin E. For heparin the anticoagulant activity of the pure substance is now taken as 100 instead of 500 units per mg. and the unit of activity has been redefined as the activity of 0.01 mg. of a standard preparation. In this respect therefore the unit of heparin now conforms with the current practice in being represented by a weight of a stable preparation instead of being based on an animal reaction. A standard preparation has been adopted for general use in Great Britain. The international standard digitalis powder now in use contains 1 unit of activity in 0.08 g. instead of in 0-1 g. as stated; this was the activity of the original standard powder. Attention is drawn to these facts as the emphasis of the book is ana-lytical. The need for another edition will afford an opportunity for incorporating these alterations in the text. The book can be recommended as an introduction to theoretical and practical physiology. S. W. F. UNDERHIL
