our eyes to fecm indivifiblcjwe not diftinguiftiing any difference 

 of parts in it without the help of a multiplying glafle : as in the 

 lead kind of mites, and in wormes picked out of ch Wrens hands 

 we dayly experience. So as it is evident that no lenfible part can 

 be unmingled. But then again, when we call to mind how we 

 have (hewed that the qualities which we find in bodies do rcfult 

 out of the compoiition, and mirtion of the Elements, we muft 

 needs conclude, that they muft of necefficy remain in their own. 

 efleiiccs in the mixed body. And fo out of the whole difcour(e, 

 determine that they arc not there in any vifible quantity, but in 

 thole leaft atomes, that are too fubtilc for our fenfes to difccrn. 

 Which pofition we do not undcrftand fb Metaphysically as to 

 fay that their fubftantiall forms remain actually in the mixed 

 body ; but onely that their accidcntall qualities are found in the 

 compound ; remitting that other queftion unto Metaphyficuns 

 (thofe fpirituall Anatomifh) to decide.

OfRarffitttiott *d Condenfation, the two firft motions 

 ff particular bodies. 



OUr intention in this difcourfe, concerning the natures and 

 motions of bodies, aiming no further then at the difcovery 

 of what is or may be done by corporeall Agents; thereby to de- 

 termine what is the work of immaterial & fpirituall fubftances ; lowing chap- 

 it cannot be expected at our hands that we fhould deliver here 

 an intire and complete body of naturall Philofbphy. But onely 

 that wefliould take fo much of it in our way, as is needfull to 

 carry us with truth and evidence to our journeyes end. It be- 

 longeth not then to us to meddle with thofc fublime contem- 

 plations which fearch into the nature of the vafi Univerfe, and 

 that determine the unity and limitation of it ; and that (hew by 

 what firings, and upon pinnes, and wheels, and hinges, the 

 whole world moreth : and that from thence do afcend unco 

 an awfull acknowledgement and hucnble admiration of the 

 primary cauft ; from whence, and ef which, both the being 

 of it, and the beginning of the firft motion, and the continuance 

 otall others doth proceed and depend. 



Nor indeed would it be to the purpofe for any man to fail ift
