104 The consequences of the

volving planet to change Its direction; besidesthe other inconsistencies in such a suppositi-on (»), it is observable that this but multipliesthe necessity of the action of the first Being,out of an unwillingness to admit it. Forthat centripetal impulse, which is necessaryto be given to the revolving body in everypoint of its orbit, must be supposed to begiven here to every part of this fluid, in everypoint of its revolution; since it is supposeda fluid, and not a continuous, solid mass. Theevasion contrived for this, viz. an universalFlenum, whereby the extreme parts of anyvortex are kept in by the confines of theneighbouring vortices, hath been shewn tobe false, N p 2, of this. And allowing itwere true, the motion consumed by attriti-on at the extremes, ought to be renewedat the center by the power of the fameBeing (0). There is also this particularthat merits our attention in the motion ofthese great bodies, that it is this centripetalimpulse that keeps the projectile force con-
