Letter from [Joseph Ernest] Petavel, The University, Manchester, to the Assistant Secretary of the Royal Society, London 'Dear Sir, the first numbers of the Proceedings sent me on my election as a fellow were Nos. A. 530 and B. No 532. I have since acquired the preceding volumes of the new series. Could you send me the first numbers of the current volumes to complete the set? I should also be obliged if you would forward me postcards indicating the subject of the papers to be read at the weekly meetings of the Society. Yours truly, J.E.Petavel.-'. 22 November 1907
