The bibliographical story of "Ink" is replete with many interesting episodes, anecdotes and poetical effusions. Its chemical history is a varied and phenomenal one. Before the nineteenth century the ink industry was confined to the few. Since then, it has developed into one of magnificent proportions. The new departure, due to the discovery and development of the "Aniline" family of fugitive colors, is noteworthy as being a step backward which may take years to retrace. The criminal abuse of ink is not infrequent by evil- disposed persons who try by secret processes to reproduce ink phenomena on ancient and modern documents. While it is possible to make a new ink look old, the methods that must be employed, will of themselves reveal to the examiner the attempted fraud, if he but knows how to investigate. How to accomplish this as well as to give a chronological history on the subject of inks generally, both as to their genesis, the effect of time and the elements, the determination of the constituents and the constitution of inks, their value as to lasting qualities, their removal and restoration, is the object of this work. There is also included many court cases where the matter of ink was in controversy; information respecting ancient MSS. and the implements and other accessories of ink which have from time to time been employed in the act of writing. To make a comprehensive review of the past in its relationship to ink has been my aim. In the construction of this work recourse has been had to the so- called original sources of information. In these, the diversity of their incomplete statements about different countries and epochs has offered many obstacles. In presenting my own deductions and inferences, it is with a desire to remove any impressions as to this volume being a mere compilation. "Facts are the data of all just reasoning, and the elements of all real knowledge. It follows that he is a wise man who possesses the greatest store of facts on a given subject. A book, therefore, which assembles facts from their scattered sources, may be considered as a useful and important auxiliary to those who seek them." A prolonged and continuous intercourse for over a quarter of a century with ancient and modern MSS., with books and other literature, with laymen and chemists, with students and manufacturers, together with the information and knowledge derived from experiment and study of results may enable the author to make the subject fairly clear. Effort has been made to avoid technical words and phrases in that portion treating of the Chemistry of Inks. This work will no doubt be variously considered. Criticism is expected, indeed it is gladly invited, for thereby may follow controversy, discussion and perhaps legislation, which will bring about results beneficial to those who are to follow after us.
