the mind became susceptible of the sensation of 

 cold. 



CCCCXII. Persons have frequently died from 

 the effects of anger and fear; but the proximate 

 cause of death in these two passions is as opposite 

 as the feelings by which they are accompanied. In 

 the former, from the expirations being long conti- 

 nued and violent, the return of the blood from the 

 head is impeded, and apoplexy is the consequence; 

 but, in the latter, the head and the surface of the 

 body have less, and the lungs more, of this vital 

 fluid, than in the natural state of the system. The 

 surcharge of the lungs explains the difficulty to 

 which the heart is opposed in circulating the 

 blood, and, when the accumulation is great, ac- 

 counts also satisfactorily for the complete cess- 

 ation of the action of this organ. 



CCCCXIII. It might probably be expected 

 that we should here treat the subject of Melan- 

 choly, as being of a depressing nature ; but as 

 this belongs to the character of the tempera- 

 ment, and is rather continuous than temporary 

 in its results, it is evidently excluded from the 

 definition I have given of passion. Cheerfulness 

 has the same relation to the previous class we 

 have considered, that melancholy has to that of 

 the depressing; and it is from the same reasons 

 that it was not mentioned when I glanced at 

 some of the peculiarities of exciting passions.
