Page 283 - He wn.s affected with symptoms similar to those before described, and died in ten minutes after the poison was applied. On opening the thorax, immediately after death, the heart was found to have ceased contracting, and the blood in the cavities in the left side was of a scarlet colour.
Page 280 - Aconite, Exp. 18. I made a wound in the side of a young rabbit, and introduced, between the skin and muscles, about twenty drops of the juice of aconite. Twenty-three minutes afterwards he was affected with symptoms, in all essential respects, similar to those, which occurred in an experiment already related, where the juice was injected* into the rectum, and at the end of forty-seven minutes from the application of the poison, he was apparently dead.
Page 277 - EXPERIMENT 13. Less than a drop of this oil was applied to the tongue of a young cat. Instantly violent convulsions took place in all the muscles, and the respirations became very frequent. In five minutes after the application, she lay on one side insensible, with slight spasmodic actions of the muscles. At the end of eleven minutes she retched, but did not vomit. In a quarter of an hour she appeared to be recovering. I repeated the application of the poison, and she was again seized with...
Page 276 - ... heart resumed its action in one instance on the division of the pericardium, and I have found that the voluntary muscles of an animal killed by this poison,, are as readily stimulated to contract by the influence of the VOLTAIC battery, as if it had been killed in any other manner. At the same time, however, that the infusion of tobacco destroys the action of the heart, it appears to destroy also the functions of the brain, since these did not return in the last experiment ; although the circulation...
Page 269 - ... perfectly motionless and insensible ; the breathing was laboured and stertorous, and the pulsations of the heart were very frequent. He continued in this state for seven or eight minutes; then began to recover; the respirations became easier, and presently he stood up, and was able to walk. Exp. 2. I injected an ounce and a half of proof spirits into the stomach of a large full-grown rabbit, by means of an elastic gum tube passed down the oesophagus. The same symptoms took place as in the last...
Page 274 - ... 3. There is reason to believe that the poisons, which in these experiments were applied internally, produce their effects through the medium of the nerves without being absorbed into the circulation. 4.
Page 400 - In about ten days afterwards the child became somewhat costive, without aay other apparent indisposition; but at this period it was seized with vomiting and convulsions, and suddenly expired. The unhappy parent now experienced a return of her complaints, and, under a persuasion of the inefficacy of professional aid, she was prevailed upon to consult an empiric, whose attendance, though continued to the end of the year, proved unavailing; and on the 3d of January, 1809, she had the advice of Mr. Chevalier,...
Page 274 - Exp. 9. An ounce of very strong infusion of tobacco was injected into the rectum of a cat. Symptoms were produced similar to those which occurred in the last experiment, and the animal died at the end of seven minutes from the time of the injection. On opening the thorax immediately after death, the heart was found extremely distended, and to have entirely ceased acting, with the exception of a slight tremulous motion of the auricles.
