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


See the first enclosure to the letter from Osbert Salvin, 20 June 1868.
In Origin, p. 386, CD remarked that Charles Lyell had told him of a Dyticus (or Dytiscus: a water-beetle) caught with an Ancylus (a freshwater shell like a limpet) adhering to it. In his letter of 14 August 1863 (Correspondence vol. 11), Robert Swinhoe had written to CD of a flamingo that had its legs covered with barnacles. CD was interested in possible vectors for the distribution of organisms.


CD thanks OS for answering his questions and especially for giving the case of the sandpiper; "such little facts are my delight". [See 6253.]
