Cohesion (Third Paper)

To re-state and add further evidence in favour of an electrical theory of cohesion. To provide tentative empirical formulae for the expression of inter-molecular forces. The author defines cohesion as the net attraction (i.e., balance of attraction over repulsion) between molecules which are relatively chemicaly saturated, at distances not greatly exceeding the molecular diameters, and the following formula is proposed for this attraction: t2 = Gm2/a(2 + 4d0/d) where G is the Newtonian constant of gravitation, m the molecular mass, d the molecular interval (centre to centre), and d0 is the molecular diameter.
