Down, | Beckenham, Kent.
Ap 29. 1877.
Dear Sir,
Allow me to thank you much for your kindness in having sent me your beautiful memoir on Brisinga.1 It contains discussions on several subjects about which I feel much interest. I congratulate you on your discovery of the new process of Autography which promises to be of much service to those who like yourself are good draughtsmen.2
With the most sincere admiration for your varied works in Science, I remain, | dear Sir | Yours very faithfully | Charles Darwin
