To P. H. Gosse 28 September 
Down, Bromley, Kent,
September 28, 1856.
My dear Sir,
I thank you warmly for your extremely kind letter,1 and for your information about the bald-pate, which is quite sufficient.2 When we meet next I shall beg to hear the actual coo!
I will by this very post write to Mr. Hill,3 and will venture to use your name as an introduction, which I am sure will avail me much; so you need take no trouble on the subject, as using your name will be all that I should require.
With my sincere thanks, Yours truly, | Ch. Darwin.
I am very anxious to get all cases of the transport of plants or animals to distant islands. I have been trying the effects of salt water on the vitality of seeds—their powers of floatation—whether earth sticks to birds’ feet or base of beak, and I am experimenting whether small seeds are ever enclosed in such earth, etc. Can you remember any facts? But of all cases whatever, the means of transport (and such I must think exist) of land mollusca utterly puzzle me most.4 I should be very grateful for any light.
Thanks PHG for information about the bald-pate pigeon.
Will write to Richard Hill.
Can PHG remember any facts relevant to transport of animals and plants to distant islands?
