 t^rms then real explications. For,to 

 omit divers of the Arguments men-

 Colours, and other Qualities as may 

 be found in the changed portions of 

 matrer we are fpeaking of. And 

 which is more,what they call by thefe 

 . and the like names, cannot be done 

 without Local motion tranfpofing the 

 particles of the matter , and confe- 

 quently producing in it a change of
