36 THE LAWS OF ORGANIC 



warmth applied to the surface of the body, or 

 by the application of friction, heat is generated 

 in increased proportion, because the lungs, by 

 these means, are indirectly relieved of a portion 

 of blood, either natural or foreign to their normal 

 function. 



XLIV. If the circulation of blood in the lungs 

 be impeded by an increased 'quantity being de- 

 termined to them, as by the depressing passions 

 of the mind, by the paroxysm of spasmodic 

 asthma, nausea, cold, and soporific medicines, the 

 evolution of heat is proportionately lessened. 



XLV. In the different inflammations and 

 fevers of the system, the blood, with few ex- 

 ceptions, has the bufFy coat proportionate to 

 the degree of disturbance in the respiration and 

 circulation. It is found, from experience, that 

 inflammation of the thoracic viscera exhibits this 

 appearance in a more marked manner than the 

 same occurring in the abdomen. This is to be 

 attributed to the greater disorder of the respira- 

 tory functions ; but these are sometimes as much 

 deranged by acute diseases of the latter cavity as 

 by their own affections ; and when this is the 

 case, the appearance of the blood is of the same 

 character. 



XL VI.- The bufFy coat is seldom or never 

 present without having been preceded or accom- 

 panied by an augmentation of animal tempera- 

 ture ; in fine, its extent is generally observed to 

 bear a ratio to the increased temperature, and
