**Dp**, Dactylopore.- If we denote the critical volume, pressure and temperature by Vk, Pk and Tk, then it may be shown, either by considering the characteristic equation as a perfect cube in v or by using the relations that
**dp**/dv=o, d 2 p/dv 2 =o at the critical point, that Vk = 3b, Pk= a/27b2, T ic = 8a/27b. - +mp4dp4 +...) =exp Mp g
**dp**4+ï¿½ï¿½ . - Recalling the formulae above which connect s P4 and a m, we see that dP4 and
**Dp**q are in co-relation with these quantities respectively, and may be said to be operations which correspond to the partitions (pq), (10 P 01 4) respectively. - But by Green's transformation f flpdS = f f PPdxdydz, (2) thus leading to the differential relation at every point = dy
**dp**The three equations of equilibrium obtained by taking moments round the axes are then found to be satisfied identically.
