“26th Ex.: I had opened the thorax of a dog and kept its life up by artificial respiration, having also cut the nervi vagi. Everything had gone as we desired. The heart worked vigorously and regularly, and the animal had full consciousness and sensitiveness. On applying the electrodes of Neif to the heart, its regular movements ceased immediately.”--_Ibid._, p. 134.
Prof. Panum states that he has “employed” a great number of animals in experiments of transfusion and injections of putrid humours. For experiments on death by embolism he has employed some eighty dogs and rabbits.--“_Experimental Observations_,” _Virchow’s Archiv._, Vol. XXIX., 1864.

“M. Vulpian injected under the skin of rabbits saliva collected at the very moment of the experiment, from perfectly healthy individuals, and this injection killed the rabbit so inoculated in forty-eight hours. The blood of these rabbits was found to be filled with microscopic organisms; among which was a special organism discovered by M. Pasteur in the course of his experiments with inoculation of the saliva of a child who had died of rabies. One drop of this blood, diluted in ten grammes of distilled water, and injected under the skin of other rabbits, also brought on the death of these animals; the blood of which was similarly filled with microscopic organisms. These singular results, of which the interpretation is by no means easy, present also the no less singular peculiarity of not being stable. Rabbits placed in identical conditions, and inoculated with the same saliva, experienced no ill effects from their inoculation, and continued in excellent health. It would therefore appear that experimental microbiology is not yet on the way to become either an easy or clear science, notwithstanding M. Pasteur’s _fiat lux_.”--_Brit. Med. Journ._, April 9, 1881, p. 571.
