7 Camden Street, N.W. - ADM has found 'a mechanical mistake which I find in all writers - Poisson states it broadly in his last edition. I take the case of it which belongs to a point vdv = Xdx + Ydy + Zdz throwing out reactions, which produce no effect', which he then works out. In a postscript he shows a simple construction to find the centre of gravity of a four sided figure.
