From John Beddoe   [22 August – 12 September 1869]1

Professor Christison,2 | Arroquhar, by Glasgow

My dear Sir

Your letter has followed me hither, where I am enjoying a holyday—3 And by the same post I have received the result of the last examination of data—4 It is vexatiously subversive of my former inferences, & really looks very much as if the gradual darkening of colour were the real cause, or main cause at least, of the whole set of phenomena—5 Now that I have got a trustworthy amanuensis6 I will have the 35–45 women abstracted from the books which furnished the original data for my paper of 1863;7 and when I get the result you shall have it at once—8

Yours very faithfully | John Beddoe
