A Trtatife of BODIES. Chap, 17. 



an uncertain duration. Sotliefe win-.is being compored of bodies 

 in a determinate proportion heavier then the aire , do run their 

 courie from their height to the ground, where they are fupported 

 (as water is by the floore of its channell) whiles they perform 

 their carreerjthat is, untillthey be wafted either by the drawing 

 of the {im,or by their (ticking &incorporating into groflcr bodies 

 Some of thelc winds according to the complexion of the body 

 out of which they arc extracted, are dry; as chofc which come 

 from barren mountains covered with fnow: others are moift, as 

 thofe tlmcome out ofmariftiy or watry places: others have o- 

 ther qualities; as of heat, or cold, of wholefbmndlc.or unwhol- 

 fomnefle, and the like; partly from the (burce, and partly from 

 the bodies they are mingled with in their way. 



Such then being the nature and origine of winds;if a cold one 

 do meet in the aire with that moift body whereof otherwile rain 

 would have been made, it changeth that moift body into fnow 

 or into hail; if a dry wind nueet with a wet body it maketh ic 

 more dry, and fo hindreth the rain that was likely to be: but If 

 the wet body overcome the dry wind,it bringeth the wind down 

 along with it; as we fee when a fhoure of rain allaieth a great 

 wind. 



And that all this is fo, experience will in lome particulars in- 

 ftrucl: its as well as reafon,fro whence the reft may be evidently 

 inferred. For we c that thole who in imitation of nature would 

 convert water into ice,do take fnow or ice & mingle it with fbme 

 active dry body, that may force the cold parts of the inow from 

 it; & then they fet the water (in fome fit vefTelJ in the way that 

 thofc little bodies are to take,which by that meansentring into it, 

 do ftrait incorporate themfelves therewith, & of a fudcien do con- 

 vert it into ice. W ch procefTe you may eafily try, by mingling fair 

 armoniakc with the fnow;butmuch more powerfully by fetting 

 the fnow over the fire, whiles the glafle of water to be congea- 

 led ftands in it after the manner of an egge in fait. And thus fire 

 it (elf, though it be the enemy and deftroyer of all cold, is made 

 the inftrument of freezing. And the fame reaibn holdeth in the 

 cooling of wine with Ihow or yce, when after it hath been a 

 competent time in the fnow, they whofe charge ir is, do ule to 

 give the rclTcl that containeth the wine, three or foure turns in 

 the fnow; fo to mingle through the whole body ofthc wine,the 



cold
