DR. BOVERTON REDWOOD'S COMPREHENSIVE WORK. A TREATISE ON PETROLEUM: The Geographical Distribution and Geological Occurrence of Petroleum and Natural Gas; the Physical and Chemical Properties, Production, and Refining of Petroleum and Ozokerite; the Characters and Uses, Testing, Transport, and Storage of Petroleum Products; and the Legislative Enactments relating thereto; together with a Description of the Shale Oil and Allied Industries. BY BOVERTON REDWOOD, F.R.S.E., F.I.C., Assoc. Inst. C.E., Hon. D.Sc. (Ohio Normal University); Chemical Adviser to the Oil Trade Section of the London Chamber of Commerce, &c. AND OTHER CONTRIBUTORS. In Two volumes, with Numerous Maps, Plates, and Illustrations in the Text, $12.50. OPINIONS OF THE PRESS. "Only one as closely identified as the author of these volumes, Mr. Boverton Redwood, F.R.S.E., with its development during the last twenty-five years could hope to deal successfully with the mass of information-chemical, physical, geographical, geological and statistical-which must be included or indicated in a treatise like the present. The task has been fulfilled in an admirable manner, with the co-operation of many experts in all parts of the world whose assistance receives unusually full recognition. The result is a manual lucidly arranged, excellently indexed, and giving copious references to the extensive literature of the subject in all its branches. . . the most comprehensive and convenient account that has yet appeared of a gigantic industry, which has made incalculable additions to the comfort of civilised man.' The Times. "It has rarely been our lot to review a technical work which so happily combines theory and practice as is done in these two volumes, but unfortunately it is rarely that technical books are written by men who combine so large a practical experience with such sound theoretical knowledge as Mr. Boverton Redwood; too often the task is left to the purely scientific professor on the one hand, or the rule-of-thumb practical man on the other. It is the author's thorough practical knowledge of his subject that has enabled him to write so clearly, and this combined with the excellent illustrations must make these volumes of exceptional value to any one connected with the petroleum industry quite apart from their value as mere books of reference." Daily Chronicle. "The gigantic importance, in modern industry and commerce, of petroleum and its products, fully justifies the appearance of a work of the encyclopædic character of the two volumes before us, and their authorship could not have devolved upon a more qualified expert than Mr. Boverton Redwood. The subject is here viewed under its multiform aspects, chemical, geological, engineering and sanitary. Mr. Boverton Redwood has made in these volumes a splendid contribution to our technical literature."-Chemical News. "It has been an open secret for some time that Mr. Boverton Redwood, the well-known petroleum expert of the City of London, was engaged upon an exhaustive treatise upon his special subject, and the publication of such a work by so eminent an authority was naturally looked forward to with interest. Nor has this interest been in any way doomed to disappointment; it is, of course, no compliment to Mr. Redwood to say that this is the best work in the English language upon this entire subject, because there is no other; nor is it to be anticipated that any other is likely to be required for a long time to come, when the first forms such a thoroughly standard work. It would be impossible, within the limits of an ordinary review, to do justice to the immense mass of valuable information which is here epitomised. We have said enough To to show how wide is the range and how thorough the completeness of this monumental work criticise it effectually is out of the question, for much of it is beyond criticism, and could only have been written by a man in the author's very exceptional position. We can only congratulate him upon the admirable manner in which he has executed his task. To say that the work is indispensable to all who have to do with any of the applications of petroleum, not to speak of those engaged in its manufacture or transport, is almost a truism."—Mining Journal. "We must concede to Mr. Redwood the distinction of having produced a treatise which must be admitted to the rank of the indispensables. It contains the last word that can be said about petroleum in any of its scientific, technical and legal aspects. It would be difficult to conceive of a more comprehensive and explicit account of the geological con ditions associated with the supply of petroleum, and the very practical question of its amount and duration." Journal of Gas Lighting. "Redwood's work-published in English-gives for the first time a thoroughly complete review, in every direction, of the occurrence and treatment of petroleum. Redwood's book has aroused the liveliest interest in both scientific and technical circles, and will not be absent from any chemico-technical library " (translation). ... Dr. H.

LONDON: CHARLES GRIFFIN & CO., LTD., EXETER ST., STRAND. FOR INSPECTORS UNDER THE PETROLEUM ACTS AND FOR THOSE ENGAGED IN THE STORAGE, TRANS- WITH SUGGESTIONS ON THE CONSTRUCTION AND USE OF MINERAL OIL LAMPS BY CAPTAIN J. H. THOMSON HIS MAJESTY'S CHIEF INSPECTOR OF EXPLOSIVES AND BOVERTON REDWOOD ADVISER ON PETROLEUM TO THE HOME OFFICE LONDON CHARLES GRIFFIN AND CO. LIMITED 1901 [All rights reserved] PREFACE. THE technology of petroleum has been already dealt with in considerable detail by one of us in a work issued by the same publishers in 1896, and the reception accorded to that work may be held to justify the belief that the author achieved the object he had in view. In these circumstances it may be considered that ample information has been given on the subject, and it may therefore be well for us to state the grounds upon which we have been led to prepare this volume for the press. In the work to which we have alluded an attempt was made to present a comprehensive historical, geographical and geological account of the great industry of which it treats, in the hope that such account would not only be of general interest, but would also prove to be of practical value to those occupied in the development of new oil fields. The methods employed in the producing of petroleum in the principal oil fields of the world, in refining the crude oil and in distributing the various commercial products, were also described at length, and a similar principle was adopted in dealing with the important subject of the testing of petroleum, the practices prevailing abroad as well |
