We will send you today volume 181 (A & B) of the "Philosophical Transactions" ['Philosophical Transactions of the Royal Society']. Volume 182 will be published in the course of the present month. The Catalogue of Scientific Papers will be supplied both to Fellows and the public by Messrs Clay & Sons. I have sent forward your order to them. I believe, however, that the volume is not yet actually issued, though it will be probably out in the course of a week or so.
I am, yours truly,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
