 various but a determinate Number of Figures, 

 and perhaps alfo differing in Magnitudcj and 

 thefe mov'd, and continually kept in Motion ac- 

 cording to certain eftablifli'd Law^ or Rules; we 

 cannot fo clearly difcover the Ufes for which 

 rfiey were created, but may probably conclude, 

 that among other Ends they were made for thofe 

 for v/hich they ferve us and other Animals 5 as I 

 fliall more fully make out hereafter. It is here 

 to be noted, That, according to out Hypothejis^ 

 the Number of the Atoms of each feveral Kind 

 that is of the fame Figure and Magnitude is not 

 nearly equals but there be infinitely more of fome 

 Species than of others, as of thofe that compound 

 thofe vaft Aggregates of ^/r, Water, and Earthy 

 more abundantly than of fuch as make up Metals 

 and Minerali : The Reafon whereof may proba- 

 bly be, becaufe thofe are neceflary to the Life 

 and Being of Man and all other Animals, and 

 therefore muft be always at Hand^ thefe only ufe-

 than NeceiTities. The Reafon why I affirm the
