 may be to fhew, that by the fame means 

 the Quality may be notably varied as to 

 degrees, or other not eflential Attributes. 

 And by fome Inftances alfo it may appear, 

 thar the Quality is Mechanically expeird 

 from, or abolifti'd in, a portion of matter 

 that was endowM with it before. Some- 

 times alfo by the fame Operation the for- 

 mer quality is deftroyed , and a new one 

 is produced. And each of thefe kinds of 

 Inftances may be ufefully employed in our 

 Notes about Particular Qualities. For, as 

 to the firfi of them , there will be fcarce 

 any difficulty. And as to the fecond> frncc 

 the permanent Degrees as well as other 

 Attributes of Qualities are faid to flow 

 from ( and do indeed depend upon ) the 

 fame Principles that the Quality it felf 

 does, if, efpecially in bodies inanimate, a 

 change barely. Mechanical docs notably 

 and permanently alter the degree or other 

 considerable attribute j it will afford, 

 though not a clear proof, yet a probable 

 prefumption, that the Principles whereon 

 the Quality it felf depends are Mecha- 

 nical. And laftly i if, by a bare Me- 

 chanical change of the infernal Difpofiti- 

 on and ftru&ure of a body* a permanent 

 Quality , contefs'd to flow from its fub- 

 ftantial Form or inward Principle, be ab- 



olifli'd.
