To Henry Denny 17 January 1
Down. | Bromley. | Kent. S.E.
I am much obliged for the M.S. which I had quite forgotten & for your note.2 I am glad to hear that you have resumed your long discontinued labour on the Anoplura,3 for I always thought that they would lead to valuable & curious results.
Will you excuse me asking you to inform me whether the Chiloe pediculi4 form a distinct species or well-marked variety? Is it the case that the Lice differ on different races of man; & can you believe, from any other evidence which you may possess, the statement by Mr Marshall about the Polynesian lice not living on a distinct race of man?5 I shd. be grateful for any information on this head, especially if you would permit me to quote you as my authority.6 But perhaps you will not have spare time to write to me on this head.—
Pray believe me | Dear Sir | Yours very faithfully | Ch. Darwin
Pleased to learn that HD has resumed research on Anoplura.
Are Chiloe pediculi a distinct species?
Do lice differ on different races of humans?
Is there evidence supporting Mr Marshall’s statement about Polynesian lice?
