Letter from Wiliam Edward Ayrton, on his paper with W R Cooper 'Variations in the electromotive force of clark cells with temperature' to the Secretary of the Royal Society Their paper has already been published in the Proceedings, as they felt it wasn't of enough weight for Philosophical Transactions. He is aware that papers of a 'superexcellent' nature should appear in Philosophical Transactions and if the Council regard the paper to be of this nature, he will be 'quite content'. Subject: Physics [Published in Proceedings of the Royal Society, 1895]. 21 January 1895
