Subject: Chemistry Prints of these diagrams were published in volume 40 of the Proceedings of the Royal Society alongside the paper 'Electrolytic conduction in relation to molecular composition, valency and the nature of chemical change: being an attempt to apply a theory of "residual affinity."'. 1886
