anxiety, the color changed from the clay-cold death-look to the full flush of the warm hue of life, and she joyfully exclaimed, "Oh! I feel well!" When the removal of carbonic acid gas had made way for oxygen to be brought to the yet uninjured lungs, the carbon of the venous blood ignited, the motive power was furnished, the blood was again moved forward into the arterial system, and the dammed up venous current, receiving the suction force, rushed on so violently as at times nearly to produce suffocation; but the struggle was soon over, and the lungs, free both from carbonic acid gas and an unnatural quantity of venous blood, once more received pure air--and to the relieved sufferer respiration became delightful--the circulation passed freely through an unbroken system--and THE CHOLERA WAS CURED. Was there, in the whole wide world, another person besides myself who would have taken such a living corpse, dragged it out of doors, and set it upright, on feet which could not feel, with the expectation that it might breathe out death, breathe in life, and be restored? The result is a proof, _a posteriori_; that the theory on which the experiment was made is true. Other cases occurred, where, under different circumstances, cures of cholera were effected. One, as instantaneous, and in some respects as remarkable as that of Jane Phayre, was that of my friend and former pupil, Mrs. Gen. Gould, of Rochester, who sent for me, believing herself to be dying of cholera. I have her letter, which, by permission, is published in my work on Respiration; and also a letter from her physician, Dr. Bloss, of Troy, testifying that her disease was cholera, and that he had little hope of her restoration. This letter is published in the appendix of a report on my theory, read in Buffalo, August 8th, 1851, to a convention of the New York State Association of Teachers.
