To F. T. Buckland   29 February [1868]1

Down. | Bromley. | Kent. S.E.

Feb. 29th

My dear Sir

Many thanks for your kind note & various pieces of information.— I will write to Mr Bush about the Rats.—2 In relation to the fecundation of ova, you may perhaps like to hear that I tried with much care on rather large scale the effect of very little pollen & an immense supply—& there was no difference in the number or weight of the seed, or in their germination.— With all plants more than one grain, generally 10–40 are requisite for fertilisation.—3 I return the enclosed, which I have been glad to see, but it must, I shd. think, be charlantanry.—4

I already possess a pamphlet entitled “La Loi de Production des Sexes, par M. Thury”.—5

With many thanks, My dear Sir | Yours sincerely | Ch. Darwin
