This position, which is extremely convenient for the experimenter, is no doubt far less so for the animal experimented upon.… As Legallois had affirmed, probably from the results of his own experiments on rabbits, ‘that by tying an animal down on its back its temperature may be sufficiently lowered so as even to cause death, if it is kept long enough in that position,’ I thought I ought to repeat that experiment by prolonging its duration.”--_Mémoire sur l’Influence du Système Nerveux sur la Chaleur Animale_, Paris, 1820, pp. 11 and 12. “After long and conscientious researches, M. Chossat concluded that the sympathetic nerve is the real heat-producing agent in animals. But if, after having cut the brain transversely in front of the pons varolis, after having suppressed all nervous action by a cerebral shock violent enough to cause death, after having cut both the pneumo-gastric nerves, after having made various sections of the spinal cord, after having dissected out the sympathetic nerve above the solary plexus, after having practised ligature of the aorta below the diaphragm; if after all this, the temperature of the animals submitted to these mutilations has been lowered and they have died, notwithstanding that pains were taken to keep up artificial breathing when natural respiration was becoming impossible, it cannot be right to affirm that these animals died from the effects of cold. In the experiments made by M. Chossat, the decreased temperature was evidently the consequence and not the cause of death.”--Gavarret, Art. “_Chaleur Animale_” _Dict. des Sciences Médicales_, Vol. XV., 1874, p. 27. “M. Chossat and M. Strelzoff (very recently) have made experiments on pigeons, turtle-doves, hens, guinea-pigs, rabbits, and cats, and have arrived at this result--that the animals die when they have lost in weight thirty per cent., that is to say, one-third of their original weight.”… “M. Chossat subjected twelve animals to complete deprivation of food and drink, and abandoned them thus until they died. He examined them all every twenty-four hours at noon and at midnight.”--Gavarret’s “_Animal Heat_” p. 394. =Chudzinski= (Prof.), Paris.
