Form IV. We may likewife admit of hill more extenfive 
combinations; when, at the fame time that a clutter of ftars 
is forming in one part of fpace, there may be another colleCt- 
ing in a different, but perhaps not far diftant quarter, which 
may occafion a mutual approach towards their common center 
of gravity-

attraCt them ; fo -that upon the whole there is evidently a field 
of the greateft variety for the mutual and combined attractions 
of the heavenly bodies to exert themfelves in. I fib all, there-

At firft fight then it will feem as if a fyftem, fuch as it has 
been difplayed in the foregoing paragraphs, would evidently 
tend to a general deftruCtion, by the fhock of one far’s
