 have no rotation, fo that the particles of it are 

 aduated only by the forces of cohelion and of 

 attrad:ion. 



It is then clear, that ever/ particle taken away 

 by attrition from the parts above the level of 

 the fea, and depofited under the furface of it,

gravity of the whole j fo that, in time, if thi 

 body is homogeneous, all the points of the fur

 and approaches nearer to the JlaticaL 



While this change is going forward in the
