Excerpt from Inks Their Composition and Manufacture: Including Methods of Examination and a Full List of English Patents
Some three years ago we were engaged in a scientific inquiry as to the composition of certain fluids used as writing ink. As this work led us beyond the limits anticipated, and to the making of many experiments not actually required at the time, and as there is need for a volume dealing adequatelv with the subject, we thought it advisable to embody the results in book form. \ve found, it is true, a few small books on ink and many allusions to ink-making in old volumes and isolated papers in scientific journals but it seemed to us that the matter required more comprehensive treatment, and the present work may be regarded as an attempt to supply that want.
As far as time permitted we have tested the various formulae quoted, but, as may be seen by reference to the patent list at the end of the book, there are so many cases of slight variations in com position that we have often contented ourselves with a record of the statements put forward.

Excerpt from Inks Their Composition and Manufacture: Including Methods of Examination and a Full List of English Patents
Shortly after the appearance of the first edition of this book my old friend and fellow-worker, Mr. T. C. Hepworth, died, and in preparing this new edition I have constantly missed his unrivalled knowledge of photography and colour printing. To indicate the additions for which I am solely responsible I have used the term "the writer" in place of "the authors."
I must renew my thanks to those who gave their assistance in the writing of the first edition, and I have the further pleasure of acknowledging help from several new sources.
Mr. Albert Osborn, of New York, has kindly allowed me to reproduce illustrations from his standard work Questioned Documents, and has sent me details of the results obtained with the special microscope that he has invented for the examination of inks. My thanks are also due to Messrs. Bausch and Lomb, of Rochester, U.S.A., for the loan of the block illustrating this instrument.
One of the chief developments of recent years in the ink industry has been the discovery of "fast" aniline pigments suitable for printing inks, and I have therefore dwelt at some length on this question in the section on the examination of dyestuffs.
In this connection I must thank. Messrs. Read and Holliday (British Dyes, Limited) for valuable information as to the prospects of the colour industry in this country.
