My dear Sir

I am sorry to trouble you but may I beg you to inform me how you get on. I must come up on June 3^d. & w^d. call on you early on Tuesday morning the 4^th, if you can see me. I w^d bring up a few more specimens & some of your drawings which require a few small corrections. Possibly we might so arrange it, that some of the more simple drawings might be done direct on the Copper.— I must beg & urge you to despatch; for really I must return the specimens before very long.—

I could give a list in order of the species, & by making merely the rudest outlines we might perhaps arrange it, so that you might begin to engrave.— The Council of Pal: Soc: urge me on; but my answer to everyone is that my M.S. is & has been for some time ready, & all depends on you.—

Please to let me hear soon.—

Your’s very sincerely | C. Darwin
