History, you have changed your abode; I further see that the change has not at all induced a change in your Natural History pursuits. I write for the chance of your being able to assist me: I am investigating the slight powers of excavation which Verruca stümia /= Clisia striata) possesses; & I am am anxious to obtain specimens, either dry or wet, attached to rocks or other substances (excepting Laminariæ or seaweeds) non calcareous & some (almost equally valuable to me) on limestone rocks for comparison. The only very few specimens which I have hitherto seen on any rocks, came from Devonshire. Can you aid me? I believe you will kindly be willing to do so, if in your power. Pray believe me, My dear Sir Yours sincerely Charles Darwin Have you continued your interesting researches on the metamorphoses of the Cirripedia?"
