by Alfred Naquet

"Legal Chemistry" by Alfred Naquet is a scientific publication written in the late 19th century. This work serves as a guide for the detection of poisons and the examination of various substances, such as tea and blood stains, in the context of chemical jurisprudence. It aims to provide methods for legal chemists to effectively analyze samples in criminal cases relating to poisoning and other legal matters. The opening of the book introduces the concept of legal chemistry and its significance in the justice system, especially concerning cases of poisoning. Naquet outlines the essential role of the legal chemist in determining the presence of poisons in various biological samples and describes the importance of precise chemical analysis to avoid errors. He also highlights the broad range of investigations that legal chemists might undertake, including the examination of firearms, alterations in writings, and the falsification of coins, while emphasizing that the methods presented, though compact, aim to provide a clear understanding of the analytical techniques involved.
