Whether the same effect would follow the partial 

 destruction of the spine, as he believed the sto-

 the brain. To place the question beyond doubt 

 the following experiments were performed, 58,

 we shall pass to the next. 



In a full groAvn rabbit a small wire was intro- 

 duced into the spine at the fourth lumbar verte- 

 bra, by which the spinal marrow was destroyed 

 as far as the lowest dorsal vertebra. " Respira- 

 tion was a little disordered. In a short time af-

 observed it to be very cold, and it shivered, al-

 other rabbits, who shewed no signs of being

 58, also seemed cold, but not in the same degree. 

 The respiration now seemed much disordered, and 

 the animal refused parsley. It died in 27 hours 

 after the operation."* After death the follow-

 The membrane of the trachea and bronchia was
