To Henry Thomas De la Beche 19 August 
Down Farnborough Kent
My dear Sir Henry
I did not write to thank you for your kind note, until I knew Studer’s plans. He has been here & I now find that he is too much pressed for time to visit your working party, though on his return from Wales, he will perhaps return by the great Holyhead road.
He is much obliged to you for your kind offer & would have liked very much to have accepted it.— He is going to visit the Edinburgh Forbes.—1
I am glad to hear about the very old rocks under the Silurians;2 there is something so grand & mysterious at these depths.—
With my thanks, believe me | dear Sir Henry | Yours sincerely | C. Darwin
Bernhard Studer has been at Down. Studer will not be able to join HDelaB’s Ordnance Survey working party.
CD is glad to hear about very old rocks under Silurians. "There is something grand and mysterious at these depths."
