The structure of elastic jellies
Transactions of the Faraday Society
When I was invited to take part in this discussion, I expressed the desire not to be entrusted with the responsibilities of an introducer, but to leave this in younger and more vigorous hands. As, however, I have been put down for the part, I will endeavour to fulfil it as best I may, and appeal for indulgence in any inevitable shortcomings. I take it that the three possible views of such a structure are-1. That of a simple emulsion of spherical or more or less distorted globules in a liquid
... ules in a liquid medium. 2. A sponge-like structure, containing in its pores either the suspension liquid, or a liquid solution of the colloid, but two-phased in the sense that the pores are of microscopic and not molecular dimensions, and open ended, and that the two phases are therefore chemically independent and mechanically separable. A more or less solid solution of the exterior solution in the colloid, in which both constituents are within the range of the molecular attractions of the mass, and which are in chemical and electric equilibrium with the external liquid when one exists. Such a solid solution therefore constitutes a single phase in equilibrium with a real or virtual external solution.
