............................................................................................................................. Description Things, they say, are seldom what they seem. This ' statement is particularly true of documents which, from the literary forgeries of Ossian to the typewriter controversy of the Hiss case, have often been attacked and exposed as false. There have been occasions when history has been changed by documents subsequently proved forgeries, and a scrap of paper can send a man to the gallows. The examination of suspect documents is therefore a tremendously important task, and the establishment of authenticity is a difficult and complicated process, embodying the most recent developments in microscopy, photography and micro-chemical analysis. Dr. Harrison has had over twenty years' experience and is the Director of the Home Office Forensic Science Laboratory responsible for the examination of documents for the police forces of England and Wales, and for many government departments. He has written a book which, lavishly illustrated, provides a wealth of information on the deciphering of erasures, the chemical analysis of ink, the identification of finger-prints, the discovering of invisible writing, the establishment of the age of ball-point pen documents, the tracing of writing, the authorship of type written matter and many similar subjects. Now that this information is available, anyone concerned with documents — whether as the subject of criminal investigation, evidence in legal proceedings, or in some other way — must refer to this book. It may be disastrous not to. ............................................................................................................................. Contents 1. Introduction 2.
