|Description||'Dear Sir, |
Referring to your postcard of March 15, I hardly know how to advise you about Lord Rayleigh's optical papers, which you enquire for. Reprints of papers nearly 30 years old are very hard to obtain, and I don't suppose Lord Rayleigh is likely to have any by him. I am afraid all we could do would be to send you the originals. Could you give the titles of those you most need. We do not posses a collected reprint of 1883.'
