# 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 amanuensis^{6} 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
