"On adipocire, and its formation" by Charles Mayer Wetherill is a scientific publication from the mid-19th century. This work explores the chemical and physiological processes surrounding the formation of adipocire, a waxy substance that can form during the decomposition of animal tissues. Wetherill delves into the historical and experimental backdrop of adipocire, discussing various theories and experiments that aim to understand its nature and formation mechanisms. The book presents an in-depth examination of the formation of adipocire from various sources, including human and animal remains, through a comprehensive review of historical discoveries and Wetherill’s own experimental research. He recounts different scientists' experimentation with animal tissues and their observations on how environmental factors, such as moisture and temperature, contribute to the transformation of flesh into adipocire. Wetherill further discusses the chemical composition of adipocire, including the various fatty acids involved, and draws conclusions about its origins, suggesting it is primarily derived from the fat of the bodies rather than from the decomposition of muscle proteins. Ultimately, the work provides a detailed account of a unique aspect of biochemical processes in post-mortem conditions, appealing to those interested in anatomy, chemistry, and forensic science.
