“Before this disease, he was not observed to be of a lumpish dull spirit, his memory was happy enough, and he seem’d chearful and nimble enough in body; but since the violence of his fever, his writ seem’d wholly sunk, his memory perfectly lost, and his body so heavy and drowsie that he was not fit for any thing. I beheld him fall asleep as he sate at dinner, as he was eating his Breakfast, and in all occurrences where men seem most unlikely to sleep. If he went to bed at nine of the clock in the Evening, he needed to be wakened several times before he could be got to rise by nine the next morning, and pass’d the rest of the day in an incredible stupidity. “I attributed all these changes to the great evacuations of blood, the Physitians had been oblig’d to make for saving his life, and I perswaded myself that the little they had left him was extreamly incrustated [? incrassated] by the ardour of the fever.... Accordingly my conjecture was confirmed by our opening one of his Veins, for we beheld a blood so black and thick issue forth, that it could hardly form itself into a thread to fall into the porringer. We took about three ounces at five of the Clock in the morning, and at the same time we brought a Lamb, whose Carotis Artery we had prepar’d, out of which we immitted into the young man’s Vein, about three times as much of its Arterial blood as he had emitted into the Dish, and then having stopt the orifice of the Vein with a little bolster, as is usual in other phlebotomies, we caus’d him to lie down on his Bed, expecting the event; and as I askt him now and then how he found himself, he told me that during the operation he had felt a very great heat along his Arm, and since perceiv’d himself much eased of a pain in his side, which he had gotten the evening before by falling down a pair of staires of ten steps; about ten of the clock he was minded to rise, and being I observed him cheerful enough, I did not oppose it; and for the rest of the day, he spent it with much more liveliness than ordinary; eat his Meals very well, and shewed a clear and smiling countenance.... He grows fat visibly, and in brief, is a subject of amazement to all those that know him, and dwell with him.” This boy had been transfused for therapeutic purposes; the second transfusion performed by Denys was done upon an older man “having no considerable indisposition,” and was purely experimental. About twenty ounces of lamb’s blood are stated to have been transfused, but the procedure was without any ill effect, and it may be doubted whether the man received as much as this.
