5. It checks the nausea and vomiting, which attend the malignant state of fever. Of this I saw many instances in the year 1794. Dr. Poissonnier Desperrieres confirms this remark, in his Account of the Fevers of St. Domingo; and adds further, that it prevents, when sufficiently copious, the troublesome vomiting which often occurs on the fifth day of the yellow fever[48]. It has the same effect in preventing the diarrh[oe]a in the measles. [48] Traite des Fievres de l'Isle de St. Domingue, vol. ii. p. 76. 6. It renders the bowels, when costive, more easily moved by purging physic. 7. It renders the action of mercury more speedy and more certain, in exciting a salivation. 8. It disposes the body to sweat spontaneously, or renders diluting and diaphoretic medicines more effectual for that purpose. 9. It _suddenly_ removes a dryness, and _gradually_ a blackness, from the tongue. Of the former effect of bleeding, I saw two instances, and of the latter, one, during the autumn of 1794. 10. It removes or lessens pain in every part of the body, and more especially in the head. 11. It removes or lessens the burning heat of the skin, and the burning heat in the stomach, so common and so distressing in the yellow fever. 12. It removes a constant chilliness, which sometimes continues for several days, and which will neither yield to cordial drinks, nor warm bed-clothes. 13. It checks such sweats as are profuse without affording relief, and renders such as are partial and moderate, universal and salutary. 14. It sometimes checks a diarrh[oe]a and tenesmus, after astringent medicines have been given to no purpose. This has often been observed in the measles. 15. It suddenly cures the intolerance of light which accompanies many of the inflammatory states of fever. 16. It removes coma. Mr. Henry Clymer was suddenly relieved of this alarming symptom, in the fever of 1794, by the loss of twelve ounces of blood. 17. It induces sleep. This effect of bleeding is so uniform, that it obtained, in the year 1794, the name of an anodyne in several families. Sleep sometimes stole upon the patient while the blood was flowing. 18. It prevents effusions of serum and blood. Hæmorrhages seldom occur, where bleeding has been sufficiently copious. 19. It belongs to this remedy to prevent the chronic diseases of cough, consumption, jaundice, abscess in the liver, and all the different states of dropsy which so often follow autumnal fevers.
