to keep up the temperature as exactly as possible 110 degrees. The greatest nicety is also indispensible in using the syringe, which should be an instrument of the best make, lest a single globule of air should be injected with the fluid. I have been informed that, if, owing to unforeseen circumstances this occurs, the consequences would be instantly fatal. Mr. L. commenced the operation, and the fluid did not return, but went upward through the vein. Mr. L. whispered, “that is well.” A breathless silence ensued—one quart was injected—a slight indication of movement followed;—another quart—and another—a trembling movement of the eyelid was visible—gradually the ashy hue of death began to recede from the forehead—then from the cheek—the dawn of returning life appeared; soon afterwards, the eye changed from its fixed character of unconsciousness to that of recognition. I ventured to ask, whether, if blood could be procured, there might not be a better chance of saving the patient’s life. Mr. L. replied that no one could be found who would enter the room, much more to spare a pint of blood. Without further loss of time, I went to a neighbour next door, who had been very attentive to Susan, and who did not shew indications of fear. She was in the prime of life, in strong health, and had no family. I told her in as few words as possible the precarious state of Susan, and that the only apparent chance of saving her life, was to obtain a pint of blood, to be transferred into her vein. “Will you consent to spare that quantity? If you have the least fear about it, do not hesitate to say so.” She instantly replied, “You may take a quart if it is required.” She went with me into Susan’s room. Two basins were instantly in readiness, one floating in the other, in hot water, to prevent the blood from congealing. Mary Chapman’s vein was opened. The purple stream gushed, and well performed its benevolent design. This had scarcely been transfused to the amount of half-a-pint, when the throbbing index of life returned; and what a thrill did it give us when I was able to pronounce that “the pulse beats distinctly.” But, at this instant, it was evident by the appearance of the eye, that the utmost caution was necessary,—to avoid another extreme—apoplexy—to watch the eye as well as the pulse,—scarcely a pint could be borne—the process was instantly stayed—and the noble spirited woman was advised to return as quickly as possible to her own apartment. Her conduct throughout was heroic and cool to admiration. {65} Now on each side of the bed, Mr. L. and I took our station. The poor sufferer seemed as one awaking from a deep sleep. She knew us both, and spoke.
