- W30990513 abstract "It was just five years later, in 1842, that Dr. Julius Robert Mayer, practicing physician in the little German town of Heilbronn, published a paper in Liebig's Annalen on “The Forces of Inorganic Nature,” in which not merely the mechanical theory of heat, but the entire doctrine of conservation of energy, is explicitly if briefly stated. Two years earlier, Dr. Mayer, while surgeon to a Dutch India vessel cruising in the tropics, had observed that the venous blood of a patient seemed redder than venous blood usually is observed to be in temperate climates. He pondered over this seemingly insignificant fact, and at last reached the conclusion that the cause must be the lesser amount of oxidation required to keep up the body temperature in the tropics. Led by this reflection to consider the body as a machine dependent on outside forces for its capacity to act, he passed on into a novel realm of thought, which brought him at last to independent discovery of the mechanical theory of heat, and to the first full and comprehensive appreciation of the great law of conservation. Bloodletting, the modern physician holds, was a practice of very doubtful benefit, as a rule, to the subject; but once, at least, it led to marvellous results. No straw is so small that it may not point the receptive mind of genius to new and wonderful truths." @default.
