Dec. 17th

Dear Sir

Four Editions of the Origin have appeared; that published last month is considerably added to & can be procured through any bookseller2   I am glad to hear that you are interested on the subject.—

Dear Sir | Yours faithfully | Charles Darwin

The year is established by the reference to Origin 4th ed., which was published in 1866.
For the numerous additions to Origin 4th ed., which was published five years after the third edition, see Correspondence vol. 14, Introduction, pp. xv–xvi.
