XXXIV. It is evident, that the increased re- 

 spiration is not an effort of nature, as generally 

 supposed, to counteract the injurious agency of 

 the cold, but arises from the accumulation of 

 blood in the lungs and other internal organs, 

 which occasions a difficulty of breathing, giving 

 it a laborious and inspiratory character; and 

 therefore the tendency of this action is contrary 

 to the one taught by himself and others. 



In the subsequent chapters I shall develope 

 more fully these views, and shall also point out 

 several fallacies in the general principles of this 

 able physiologist, fallacies which do not in the 

 least impugn the correctness of his experiments, 

 but expose the inaccuracy of those premises 

 whence he has drawn his most important con- 

 clusions. 



XXXV. I have given several instances in 

 which increase of temperature is invariably the 

 result of muscular and expiratory action, but 

 have not yet adduced one in which there is a 

 diminution from muscular and inspiratory action. 

 The best example of the latter is asthma. The 

 individual who is subject to this spasmodic affec- 

 tion seeks, as soon as the symptoms approach, a 

 free current of air, from the painful sensations 

 of dissolution which accompany this disease.
