Synopsis
An Account Of Animal Secretion: The Quantity Of Blood In The Humane Body And Muscular Motion by James Keill. This early 18th?century treatise presents a rigorous mechanistic view of physiology, arguing that the animal body is a machine whose life and health depend on the orderly motions of fluids and particles. Keill develops a comprehensive theory of secretion, proposing that the blood comprises attracting particles that coagulate into corpora, and that secretions are produced within the blood before glandular separation, governed by the same mechanical principles. He formulates a series of propositions on attraction, cohesion, elasticity, and the flow of fluids, drawing connections between the coagulation of the blood, the formation of bile, semen, urine, and other secretions, and the structural roles of the lungs, liver, spleen, kidneys, and Porta. The work surveys the velocity of the circulation, the mechanics of muscular motion, and the function of glands, with experimental demonstrations (such as pressure measurements using a hogs?bladder) and detailed anatomical discussion. Keill also critiques empirical practice, arguing that true medical knowledge must derive from a solid understanding of the animal economy, and it situates Hippocrates and Sydenham within a program of rational physiological inquiry.
