# 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

## Summary

Results of CD’s examination of data subvert JB’s former inferences. Will send abstracts from the data for his paper on colour of hair of single and married women 35 to 45 years old ["On the supposed increasing prevalence of dark hair in England", Anthropol. Rev. 1 (1863): 310–12].
