To B. D. Walsh 23 March 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I am a good deal overworked with the tedious labour of correcting the proofs of my new book, but I cannot resist sending you a few lines to thank you for pleasant & kind letter of Feb 25th—2 I quite agree with what you say about the high value of disseminating scientific knowledge,—perhaps as useful as mere discovery—only you should remember that there are many who can do the one & only a few who can discover original truths.—3 Thanks for Lecture of Agassiz.4 Lyell does not believe a word about glacial action of any kind in lowlands of Brazil. If anyone had attempted to prove, even in a temperate region, former glacial action, & had owned he could find no striæ, he wd. have been laughed at.—5
I believe that the theory that glaciers are propelled by alternate freezing & thawing has been given up by all physicists.—6
I did not know about the workers’ wasps breeding.—7
My new Book will interest you or any one else very little: it will not appear till November & will be entitled “The Variation of Animals & Plants under Domestication”.—8
With many thanks for your letter—
Believe me, yours very sincerely | Ch. Darwin
Thanks for Agassiz’s Lectures. Lyell does not believe a word about glacial action of any kind in lowlands of Brazil. Agassiz’s view of glacial movement has been given up by physicists.
