and a good white after he is parted from the place. Now j'oyn- 

 ir.C this, to the experiences we hive already allowed of, con- 

 cerning the at'tra&ion of heat; we may conclude that if any of 

 thcfc vapours do light upon a fblid warm body, which hath the 

 nature of a fource unto them, they will naturally congregate 

 and incorporate there; and if thole vapours be joyned with any 

 medicative quality or body, they will apply that medicament 

 better then any chirurgeon can apply ic. Then, if the fteam of 

 bloud and fpirhs, docarry with it from the weapon or cloth, the 

 balfamike qualities of the falve or powder, and with them do 

 fcttfe upon the wound; what can follow but a bettering in it? 

 Likcwifc, if the fteam of the corruption that is upon the clod,do 

 carry the drying quality of the wind which 'fweepcth over it 

 when it hangeth high in the airc, unto the (ore part of the cows 

 foor; why is it not poflible that it fhould dry the corruption 

 there, as well as itdryeth it upon the hedge? And if thefteam 

 of b.nned milk can hurt by carrying fire tothcdtigge; why 

 fhonld not fait oft upon it, be a prefervative againft it? Or ra- 

 ther , why fhould not fait hinder the fire from being carried thi- 

 ther? Since the nature of fait, alwayes hindereth and fupprefl 

 feth the activity of fire: as we fee by experience when we throw 

 fait into the fire below, to hinder the flaming of foot in the top 

 of a chimney : which prefently ceafeth, when new fire from 

 beneath doth not continue it. And thus we might proceed in 

 fundry other effects, to declare the reafon and the poflibilicy of 

 them; were we certain of the truth of them: therefore we remit 

 this whole qucftion, to the autority of the tcftimonies.
