To John Tyndall 23 February 1
Down Bromley Kent
I send the Letters.2 No 1 tells most.— It is only an inference that Mr Wedgwood saw congelation,3 but it seems to me pretty clear that he did. Letters no 2. & 3 are hardly worth your looking at.— Letter 4 contains reference to protrusion of glaciers by the swelling of frozen unfiltrated water.— I doubt whether the letters are worth your looking at, but it has amused me to see the speculations of philosophers (my two Grandfathers) nearly 80 years ago on a subject which they so little understood. It seems that Dr D. communicated the fact to Dr Black by Mr. Robert D. (who was my Father) & who lodged with Dr Black in Edinburgh.—4
Dear Tyndall | Yours very sincerely | Ch. Darwin
PS. | I send by this Post, a pamphlet which contains the best account, pleasantly written, of my Origin, if you chance to care to read it.5
Sends correspondence between Dr Erasmus Darwin and Josiah Wedgwood I [of Etruria] on glaciers.
Also a pamphlet [Asa Gray, Natural selection not inconsistent with natural theology (1861)] containing "the best account" of the Origin.
