Description | 'Dear Sirs, With reference to your's of to-day's date, some of the lines appear not to show up at all, and the Author seems to be of opinion that new negatives will be necessary. In saying that 21/- will cover the cost of new proofs, I suppose you hardly contemplate making new negatives for that price? How much would that cost? Yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. |
