My dear Hooker

I return Murchison’s good-humoured letter.— I returned yours to him, yesterday to Huxley.¹ Your letter struck me as very clear & good.—

I also return all your lists & memoranda, which I have had all copied.—² They are very interesting to me, & will be more so, whenever I treat in full the Glacial question; when that will be God knows.— I have been much struck with the plants in Tasmania common to Europe & not found in Australia. Also with so many plants common to Europe, S. America & Australia; what an enormous range! How very curious your list from Fl. Antarctica is, showing as far as I can make out, that every plant common to the S. extremity of America & Europe is found on the highway to it ie N. America; though some plants I see, are common to N. America & T. del Fuego, which do not occur in Europe as might have been expected—: Will you just look at your own list & see if I have understood this case rightly; & I will ask you whenever we meet.—³ When that will be I know not; I had made up my mind to be at the next Phil. club,⁴ but my head feels so queer, that I am going to consult a Doctor & if he thinks anything of my symptoms, I shall go at once for fortnight to Moor Park; otherwise I shall try & put off till I have got a little more work done.—⁵

Yours affect^y | C. Darwin
