|Description||'With reference to your enquiry of the 21st instant, I have to say that the Phil. Trans. B. Vol. [Philosophical Transactions of the Royal Society, B, volume] 196 plates 7, 8, 9, 10, 14 may now be rubbed off, but the Phil. Trans. B Vol. 198 plates 12 and 13 should be kept a little longer.|
I am, faithfully yours,
