 Ecliptic, the moment would come in which, it's 

 two Poles being in equilibrio, it could prefent to 

 the Sun the Equator only. 



I acknowledge that I have no reply to make to 

 that difficulty, unlefs this be one ; We muft have 

 recourfe to an immediate will of the Author of 

 Nature, who is pleafed to deftroy the inftant of 

 this equilibrium, and who re-eftablifhes the ba- 

 lancing of the Earth on it's Poles, by laws with 

 which we are unacquainted. Now, this conceffion 

 no more weakens the probability of the hydraulic 

 caufe, which I apply to it, than that of the prin- 

 ciple of the attradion of the heavenly bodies, 

 which attempts to explain it, I am bold to fay, 

 with much lefs clearnefs. This very attradion 

 would foon deprive the Earth of all manner of 

 motion, if it alone aded in the ftars. If we would 

 be fincere, it is in the acknowledgment of an in- 

 telligence, fuperior to our own, that all the me- 

 chanical caufes, of our moft ingenious fyftems, 

 muft ifTue. The will of GOD is the ultimatum of 

 all human knowledge. 



From this objedion, however, I fhall deduce 

 confcquences, which will diffufe new light on the 

 ancient efieds of polar effufions, and on the man-
