Inks Their Composition and Manufacture - Including Methods of Examination and a Full List of English Patents #231258

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.
