THIS work, according to the preface, is intended to be “a hand-book useful to all interested in oils and varnishes, and especially to analysts, pharmacists, manufacturers, and technological students.” The editor further states that in preparing this volume he used the information in Cooley's “Cyclopaedia” which he has “supplemented from the latest publications.” The modern literature of oils and varnishes exists chiefly in the form of workshop recipes, in trade journals, technological dictionaries and pharmaceutical publications, and if anybody ever wanted to know anything about the useful and heterogeneous products comprised under these terms he not unfrequently found it necessary to waste a good deal of time in hunting up the required information. This last addition to Messrs. Churchill's Technological Hand-books will therefore be valuable to those engaged in several distinct branches of industry, and the editor has certainly displayed considerable judgment in the selection and arrangement of the scattered materials which he has brought together in this little volume of some 370 pages in length. Oils, Resins, and Varnishes. Edited by James Cameron (London: J. and A. Churchill, 1886.)
