I have just received your two works, and have made some use of them for my present book; and I should have made more use of them had I received them earlier.2 You describe the grand scenery of the Tyrol most graphically, and it makes me long to be strong and young again to ramble over the mountains. My next book will not be ready for a considerable time, though part is finished.3
I am very much obliged to you for your very interesting letter, and especially glad to hear about the co-existence of varieties in the wild state.4 The fact relating to the variation of the wild boar is quite new to me.5 I hope I shall get your book soon,6 and with my best thanks, I remain, dear sir, &c., | Charles Darwin.
