Letter to W. D. Fox, 24 October 1852

I am at work on the second vol. of the Cirripedia, of which creatures I am wonderfully tired: I hate a Barnacle as no man ever did before, not even a Sailor in a slow-sailing ship. My first vol. is out: the only part worth looking at is on the sexes of Ibla & Scalpellum; I hope by next summer to have done with my tedious work.
