204 EFFECT OF WARMTH IN PREVENTING DEATH FROM CHLORAL. 



This experiment shows the effect of warmth in preventing 

 death, and the rapidity of recovery when the nnimal is put in a 

 warm bath, compared with that which it makes when encased 

 in cotton-wool. 



All these experiments were made in August, 1870, in the 

 laboratory of my friend, Dr. Burdon Sanderson, and I gladly 

 take this opportunity of returning liim my most hearty thanks 

 for the facilities and aid he afforded, and the kindness wliich 

 he then and ever has shown me.
