A Mechanical Account of Poisons in Several Essays

An early‑18th‑century physician sets out to demystify the hidden forces behind poisons, arguing that their dreadful effects are not merely mystical but follow the same mechanical laws that govern the human body. Drawing on personal experiments with venomous snakes, arsenic, and mercury, he seeks to translate the obscure language of alchemy into clear, observable phenomena.

The author treats each toxin as a tiny machine, tracing its influence through the “motions of the fluids” and the delicate structures of organs. He blends modest laboratory work with anatomical sketches supplied by a colleague, offering concise essays that hint at a more systematic chemistry yet remain grounded in the practical concerns of physicians of his day. Throughout, he urges fellow doctors to embrace mathematical reasoning as a tool for better treatment.

For listeners, the work provides a fascinating glimpse into a period when medicine was beginning to adopt the emerging scientific method. Its straightforward prose and candid reflections on the challenges of research make it an engaging snapshot of the transition from superstition to early modern science.
