220 PHILOSOPHICAL TRANSACTIONS. [aNNO 1663. 



was to tear the clothes that were given him, to run naked abroad, and to burn 

 in the houses where he was whatever he could meet with. He moved to com- 

 passion all good people that saw him, and especially those in the Marais du 

 Temple, where he was most known, and where he had been wont to be seen 

 before this distemper as well clothed and fashioned as any one of his condition 

 could be. 



Monsieur de Montmor, among others, was the person most touched with it, 

 and resolved to employ his interest to procure him a place in one of the hos- 

 pitals. But first he thought of transfusion, and believed there would be 

 no danger in trying it upon this man, being so persuaded by many experi- 

 ments we had already made in his presence. He therefore had him taken up 

 for that end, and having sent for me and M. Emmerez to ask our opinion of 

 the fitness of trying the transfusion upon this man, we answered, that we could 

 indeed give good assurance for his life, and that the operation was in itself in- 

 capable of causing the death of any one, if discreetly managed ; but as to the 

 cure of such an extravagance as that appeared to us, we had not yet experience 

 enough to dare to promise him that, and that our conjectures went no farther 

 than to think that the blood of a calf by its mildness and freshness might possi- 

 bly allay the heat and ebullition of his blood being mixed therewith. The matter 

 having been sufficiently examined, we resolved to carry this man into a private 

 house ; and there we appointed for his keeper that porter on whom we had 

 already practised the transfusion eight months ago, both that the thing might 

 not appear so new to him as to others who never had seen the experiment be- 

 fore, and that he might serve to convince our patient and others who should be 

 present at the operation, that there was no danger in it at all. 



, December 19, we used what art we could to dispose the fancy of our patient 

 to suffer the transfusion, which we resolved should be tried upon him that night 

 about six o'clock. Many persons of quality were present, together with several 

 physicians and surgeons too intelligent to suspect them of being capable of the 

 Ifeast surprise. Mr. Emmerez opened the crural artery of a calf, and did all the 

 necessary preparations in their presence ; and after he had drawn from the pa- 

 tient about ten ounces of blood out of a vein of the right arm, we could give 

 him no more again than about five or six ounces of that of the calf, by reason 

 that his constrained posture, and the croud of the spectators interrupted very 

 much this operation. 



Meantime he found himself, as he said, very hot all along his arm, and 

 under the arm-pits ; and perceiving that he was falling into a swoon, we presently 

 stopped the blood running in, and closed up the wound. Yet he supped two
