“I prepared in a large gutta percha balloon a mixture of 100 litres of air and 255 cubic centimetres of pure oxide of carbon, which made 1/392 of poisonous gas; I then opened the jugular vein in a dog of 9 kilos., and with a long india-rubber catheter introduced into the vena cava inferior, drew out 30 centimetres of blood, put it into a flask and defibrinised it by agitating it a few minutes. The animal’s head was then placed in a gutta percha muzzle communicating with the top of the balloon containing the oxide of carbon, and the animal was allowed to breathe into it for half-an-hour. During the last two minutes a second quantity of blood was taken from the vena cava and defibrinised; then the animal was allowed to breathe in the air, and half-an-hour later a third sample of blood was taken.…”--_On the absorption of Oxide of Carbon_ (Note presented to the Acad. of Sc. by M.

Therefore, the author of this essay determined to make a series of experiments to explain the malady which is produced in rabbits by the subcutaneous injection of human saliva.”--_Arch. ital. de Biol._, Vol. II., Part I., p. 106. =Groves, J.

Dog not curarised: spinal marrow cut through at the beginning of the operation; also the vagi severed, nitrate of soda injected. “Exp. III. Dog strongly curarised, and the medulla stimulated repeatedly by galvanic currents. Injections of nitrate of soda. “Exp. VII. Dog curarised; nerves of the left kidney torn through, medulla subjected to electric stimulation. The vagi cut through. “Exp. XI. Dog curarised; nerves of the left kidney torn through, digitalis and strychnine injected. Result cramps.”--Pflüger’s _Archiv._ Vol. II., p. 370. =Gscheidlen, Richard.= M.D.; Prof. Physiol.; Direct.
