12 NATURAL HISTORY. 



the parts that are less fleshy, and more dry ; as the 

 forehead and breast. 



709. Men sweat more in sleep than waking ; and 

 yet sleep doth rather stay other fluxions, than cause 

 them ; as rheums, looseness of the body, &c. The 

 cause is, for that in sleep the heat and spirits do 

 naturally move inwards, and there rest. But when 

 they are collected once within, the heat becometh 

 more violent and irritate ; and thereby expelleth 

 sweat. 



710. Cold sweats are (many times) mortal, and 

 near death ; and always ill, and suspected : as in 

 great fears, hypochondriacal passions, &c. The cause 

 is, for that cold sweats come by a relaxation or for 

 saking of the spirits, whereby the moisture of the 

 body, which heat did keep firm in the parts, sever- 

 eth and issueth out. 



711. In those diseases which cannot be discharged 

 by sweat, sweat is ill, and rather to be stayed ; as 

 in diseases of the lungs, and fluxes of the belly : but 

 in those diseases which are expelled by sweat, it 

 easeth and lighteneth ; as in agues, pestilences, &c. 

 The cause is, for that sweat in the latter sort is 

 partly critical, and sendeth forth the matter that 

 offendeth ; but in the former, it either proceedeth 

 from the labour of the spirits, which sheweth them 

 oppressed ; or from motion of consent, when nature, 

 not able to expel the disease where it is seated, 

 moveth to an expulsion indifferent over all the body.

 well observed. Thus much we see ; that they breed
