daveric rigidity, I tied the aorta immediately behind the origin 

 of the renal arteries, in several rabbits. Shortly afterwards, 

 sensibility and the voluntary movements disappeared in the 

 posterior limbs. I waited until muscular irritability had given 

 way to what is called cadaveric rigidity ; and when that peculiar 

 rigidity had existed for at least twenty minutes, I relaxed the 

 ligature. Then circulation took place, and, in consequence of it, 

 sensibility and voluntary movements re-appeared. 



From this experiment it results, that not only local life, but all 

 the properties and actions of full life, can be restored in limbs 

 that have been in the state called rigor mortis, cadaveric or 

 post-mortem rigidity. 



4th. On a man, 20 years old, who was guillotined on the 

 18th of June, 1851, in Paris, I made an experiment similar 

 to some of the preceding. The decapitation took place at 

 8 o'clock A. M. Ten hours afterwards, i. e. ten minutes after 

 6 o'clock P. M., the muscles of the hand, upon which I intended 

 to experiment, exhibited some slight manifestations of irritability. 

 At 7 and at 7* o'clock P. M. I ascertained that they had lost 

 their irritability. Shortly after they were in a state of cadaveric 

 rigidity. 



I began the injection of blood 10 minutes after 9 o'clock P. M. 



As I wished to inject fresh human blood, and as I could not 

 obtain any from the hospitals at such an hour, I was obliged to 

 make use of my own. My friends, Drs. F. Bonnefin and Des- 

 lauriers, drew from one of the veins of my left arm half a pound 

 of blood, which was immediately beaten and completely defibri- 

 nated and filtered through a cloth. 



As, in opposition to the general opinion, I had found that it is 

 not necessary, in transfusion, to make use of blood at a tempera- 

 ture not far from that of warm-blood animals, I left the blood 

 employed in this experiment freely exposed to the atmosphere 

 during all the time of the operation. The temperature of the 

 air was 19 centigr. (66-2 Fahr.j I regret not having taker* 

 the temperature of the blood when I began to inject it, but rt 

 was probably about the same as that of the atmosphere. 



The injection was made into the radial artery, a little above- 

 the wrist. The whole quantity of the blood was injected in about 

 8 or 10 minutes. The arm operated on had been separated from
