Fourth edition.The author's popular physiological treatise, first published in 1801 and subsequently translated into many languages and editions. Based on the author's public lectures, this work established a major classification system for the life functions. Richerand treats all the major functions, from digestive to respiratory, suggesting that there are two basic classes of functions -- those that serve in the conservation of the individual and those that serve in the conservation of the species.
