In reply to your enquiry as to cost of possible reprints from our Proceedings and Transactions, I beg to send you the following approximate average figures, which may perhaps be what you require.
Reprints from Proceedings --- 750 copies. Rough average cost per sheet £12.
Reprints from Transactions -- 750 copies. Rough average cost per sheet £7. 10s.
Extensively illustrated papers would naturally be in excess of above figures. As to size, these figures are on the basis of reprinting same size as originals, viz: super royal for Proceedings papers are royal quarto for Transactions.'
