I beg to acknowledge the receipt of your letter of the 14th and also the specimens of “photoglyphic engraving”
The engravings are very excellent, and I feel deeply indebted to you for giving me so valuable a souvenir of the illustrious inventor of the process by which they are produced, and of the chief founder of the photographic art.
I am, Sir Yours very truly
