    Nysten made a number of experiments which showed that carbonic-acid gas may be injected into the jugular vein and even into the carotid without causing serious accidents, provided the gas is introduced in small doses and slowly. If, however, the operation is performed too forcibly, if the gas is introduced into the blood too rapidly and in too large a quantity, death will ensue through distention of the cavities of the heart. Against the experiments of injecting the gas into the jugularis, the objection has been made that the gas could not have time for action on the blood, because it would be transported at oncp to the lungs, whence it would be exhaled immediately. Demarquay, in repeating the ex- periments of Nysten and desiring that the gas should remain for a longer time in contact with the blood, selected the crural vein. The result corresponded exactly with the results formulated by Nysten. He injected into the cruralis of a good-sized dog, within forty minutes, i liter of carbonic acid, taking care not to inject more than.from 5 to 6 centiliters [86]
