ections parallel [15C3] particles having the same density p, will form a level surface, or stratum [13S], extending [1563v] around the ivhole body, as PTUESQ ; and in proceeding from any point T to another infinitely near point U of this level surface, we shall have d p = 0 ; and as p is a function… … d x, dy, d z, being supposed to correspond to this surface. From this equation we find, as in note 64, page 93, Vol. I, that the resultant of the forces P, Q, R, must be perpendicular to this level surface P E S (g, as has been stated by the author in [13S]. This is also evident from the…
