DISEASES OF IRRITATION. SECT. XXXII.?. 



pungency of the fluids, which they abforb, the/ 

 general caufe of their quiefcence feems to be i^e 

 too great inlipidity of the fluids of the body, co- 

 operating perhaps at the fame time with other ge- 

 neral caufes of quiefcence. 



Hence, in mariliy countries at cold feafons, 

 which have fucceeded hot ones, and amongft thofe, 

 who have lived on innutritious and unfti ululating 

 diet, thefe agues are mod frequent. The enlarge- 

 ment of thefe quiefcent vifcera^and the Iwelling of 

 the prsecordia in many other fevers, is,, mod pro- 

 bably, owing to the fame caufe; which may confiil 

 in a general efficiency of the production of fenio- 

 rial power, as well as in the diminifhed Simulation 

 of the fluids ; and wh.ep the quieicence of fo great 

 a number of glantjs, as conftitute one of thofe 

 Jarge vifcera, commences, all the other irritative 

 motions are aije$:ed by their connexion, with it, 

 and the cold fit of fever is prgduced. 



VIII. There are many other caiife$ 3 which pro- 

 duce quiefcence of fpme part of the animal fyftem, 

 as fatigue, hunger, thirft, bad djet, difappointed 

 love, unwhoiefome air, exhauftion from evacua- 

 tions, and many others ; but the lad caufe, that we 

 thall mention, as frequently productive of cold 

 fits of fever, is fear or anxiety of mind. The 

 pains, which we are firft and moil generally ac- 

 quainted with, have been produced by defect of 

 fome (limulus ; thus, foon after our natiyity \ve f 

 become acquainted with the pain from tl)e ;? cold- 

 nefs of the air, from the want of refpiration, and. 

 from the want of food. Nqw 1J tjiefe pain? pcca{ 

 floned by defect of ilimulus are attended withqui- 

 cfcence of the organ, and at the fame, time with 

 a greater or lefs degree of quiefcence of other 

 parts of the fyftem : thus, if we even endure the^ 

 pain of hunger fo as to mifs one meal inflead of 

 our daily habit of repletion, not only the perif- 

 taltic motions of the ftomach and bowels are di-
