Museum. I read it somewhere, & I believe in Annales des Sciences, & made an extract, but I have unfortunately lost it.— I cannot remember hardly anything about them: are they permanently fixed on the female? Will you just tell me this, for it will be a chance whether I can borrow any Book with an account, & I want to refer to this creature soon. Also how does the Male get to the female & how does it obtain its food? I hope you will excuse this trouble, which I cause by having in the most provoking way lost an extract which I well remember making— Kindest Remembrances to Waterhouse. My dear Sir, Yours sincerely, C. Darwin" Letter, signed by sender. Sent from Down House, near Beckenham, Kent, England. The Robert M.
