SECT.XXXU. 9. DISEASES OF IRRITATION. 



than the fecretory veffels, whofe mouths are expofed 

 to the waniith of the blood : now, as the internal 

 abforbents fympathize with the external ones, thefe 

 alfo, which during the hot fit drank up the thin- 

 ner part of the bile, or of other fecreted fluids, 

 lofe their incieafed activity before the gland loles 

 its increafed activity, at the decline of the hot fit ; 

 and the loofe dejections are produced from the 

 fame caufe, that the incieafed perfpiration Hands 

 on the fmfa^e of the fkin, from the increafed ab- 

 ibrption ceafing iboner than the incieafed fecre- 

 tion. 



The urine during the cold fit is in fmall quan- 

 tity and pale, both from a deficiency of the fecre- 

 tion and a deficiency of the abforptton. During 

 the hot fit it is in its ufual quantity, but very high- 

 coloured and turbid, becaufe a greater quantity had 

 been fecreted by the increafed action of the kid- 

 riies, and alfo a greater quantity of its more aque- 

 ous part had been a bfoi bed from it in the bladder 

 by the increafed aclion of the abforbents ; and 

 laftly, at the decline of the hot fit it is in large 

 quantity and lefs coloured, or turbid, becaufe the 

 abforbent vefTels of the bladder, as obferved above, 

 lofe their increafed action by iympathy with the 

 cutaneous ones fooner than the fecretory veffels of 

 the kidnies lofe their increafed activity. Hence 

 the quantity of the fedimenf, and the colour of the 

 urine, in fevers, depend much on the quantity fe- 

 creted by the kidnies, and the quantity abforbed 

 from it again in the bladder : the kinds of fedi- 

 ment, as the lateritious, purulent, mucous, or 

 -Woody lediments, depend on other caufes. It fhould 

 *be obferved, that if the fweating be incieafed by 

 the heat of the loom, or of the bed-clothes, 

 a paucity of turbid urine will continue to be pn> 

 duced, as the abforbents of the bladder will have 

 their activity increafed by their fympathy with the 



veflela
