| Description | 'Please put in hand accompanying figs [figures] for Phil. Trans. ['Philosophical Transactions of the Royal Society'] viz. 12 Ayrton, and 15 Poynting. Please send estimates for both, but go on with the work without waiting for acceptance. I have no special instructions for you about them, except that as being for Phil Trans, they will be black on white. As to the two Ayrton photographs, I leave them to your discretion'. |
