19. Febris inirritativa. Inirritative fever described in Class 

 I. 2. 1. 1. belongs to this place, as it consists of disordered trains 

 and tribes of associated irritative motions, with lessened actions 

 of the associated organs. In this fever the pulsations of the 

 heart and arteries are weakened or lessened^ not only in the 

 cold paroxysm, as in the irritative fever, but also in the hot pa- 

 roxysm. The capillary arteries or glands have their actions 

 nevertheless increased after the first cold fit, as appears by the 

 greater production of heat, and the glow of arterial blood in the 

 cutaneous vessels; and lastly the action of the stomach is much 

 impaired or destroyed, as appears by the total want of appetite to 

 solid food. Whence it would seem that the torpid motions of 

 the stomach, whatever may occasion them, are a very frequent 

 cause of continued fever with weak pulse; and that these torpid 

 motions of the stomach do not sufficiently excite the sensorial 

 power of association, which contributes in health to actuate the 

 heart and arteries along with the irritation produced by the sti- 

 mulus of the blood; and hence the actions of these organs are 

 weaker. And lastly, that the accumulation the sensorial power 

 of association, which ought to be expended on the motions of the 

 heart and arteries, becomes now exerted on the cutaneous and 

 pulmonary capillaries. See Supplement I. 8. and Sect.

I have dwelt longer on the vertiginous diseases in this genus, 

 both because of their great intricacy, and because they seem to 

 open a road to the knowledge of fever, which consists of associ- 

 ated trains and tribes of irritative or sensitive motions, which are 

 sometimes mixed with the vertiginous ones; and sometimes sepa- 

 rate from them.
