To Osbert Salvin 23 June 
Down. | Bromley. | Kent. S.E.
My dear Sir
I thank you most sincerely for the great trouble, which you have taken in answering my questions.— Your answers are all perfectly clear & distinct.— I am very glad indeed to hear of the case of the Sandpiper—1 such little facts are my delight. It will go well with the F. Water Ancylus attached to a Dyticus, & the Balani attached to a Flamingo’s feet.—2
With cordial thanks, pray believe me | Yours sincerely & obliged | Charles Darwin
CD thanks OS for answering his questions and especially for giving the case of the sandpiper; "such little facts are my delight". [See 6253.]
