Seite 135 - ... after respiration had ceased, I opened the thorax, and found the heart extremely distended, and without any evident contraction, except of the appendix of the right auricle, which every now and then contracted in a slight degree. I divided the pericardium on the right side. In consequence of the extreme distension of the heart, this could not be done without irritating the fibres with the point of the scalpel. Immediately both auricles and ventricles began to contract with considerable force,...
Seite 402 - Fame is the spur that the clear spirit doth raise (That last infirmity of noble mind) To scorn delights and live laborious days; But the fair guerdon when we hope to find, And think to burst out into sudden blaze, Comes the blind Fury with the abhorred shears, And slits the thin-spun life. 'But not the praise...
Seite 424 - Engravings of the Arteries ; illustrating the second volume of the Anatomy of the Human Body, and serving as an Introduction to the Surgery of the Arteries.
Seite 59 - When the brain is injured or removed, the action of the heart ceases, only because respiration is under its influence, and if, under these circumstances, respiration is artificially produced, the circulation will still continue.
Seite 147 - Jowing conclusions. 1. Alcohol, the essential oil of almonds, the juice of aconite, the empyreumatic oil of tobacco, and the woorara, act as poisons by simply destroying the functions of the brain ; universal death taking place, because respiration is under the influence of the brain, and ceases when its functions are destroyed.
Seite 143 - Erp. 27. — In order to make the experiment more satisfactorily, I exposed the sciatic nerve of a rabbit in the upper and posterior part of the thigh, and passed under it a tape half an inch wide. I then made a wound in the leg, and having introduced into it some of the woorara mixed with water, I tied the tape moderately tight on the fore-part of the thigh. Thus I interrupted the communication between the wounds and the other parts of the body, by means of the vessels, while that by means of the...
Seite 141 - Exp. 23. The experiment was repeated on a rabbit. The symptoms produced were similar to those in the last experiment; but the animal did not vomit, and the convulsive motions were in a less degree : he died eleven minutes after the poison was inserted. On opening the chest, the heart was found to have entirely ceased contracting; it was much. distended with blood ; and the blood in the cavities of the left side was of a scarlet colour. On irritating the heart with the point of the scalpel, the ventricles...
Seite 135 - ... 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 was restored, and kept...
Seite 347 - A similar advertisement, by James Monteith, appeared on 19th March, 1778: — 'Midwifery: James Monteith, surgeon (having provided the necessary apparatus), proposes, on Thursday, 26th of March, to begin a course of lectures on the theory and practice of midwifery...
Seite 67 - When the influence of the brain is cut off, the secretion of urine appears to cease, and no heat is generated; notwithstanding the functions of respiration, and the circulation of the blood continue to be performed, and the usual changes in the appearance of the blood are produced in the lungs.
