When I sent off the glacier paper, I was just going out and so had no time to write. I hope your friend will enjoy (and I wish you were going there with him) his tour as much as I did. It was a kind of geological novel. But your friend must have patience, for he will not get a good GLACIAL EYE for a few days. Murchison and Count Keyserling RUSHED through North Wales the same autumn and could see nothing except the effects of rain trickling over the rocks! I cross-examined Murchison a little, and evidently saw he had looked carefully at nothing. I feel CERTAIN about the glacier-effects in North Wales. Get up your steam, if this weather lasts, and have a ramble in Wales; its glorious scenery must do every one's heart and body good. I wish I had energy to come to Delamere and go with you; but as you observe, you might as well ask St. Paul's. Whenever I give myself a trip, it shall be, I think, to Scotland, to hunt for more parallel roads. My marine theory for these roads was for a time knocked on the head by Agassiz ice-work, but it is now reviving again... Farewell,--we are getting nearly finished--almost all the workmen gone, and the gravel laying down on the walks. Ave Maria! how the money does go. There are twice as many temptations to extravagance in the country compared with London. Adios. Yours, C. DARWIN. CHARLES DARWIN TO J.D. HOOKER. Down [1844?]. ...I have also read the 'Vestiges,' ('The Vestiges of the Natural History of Creation' was published anonymously in 1844, and is confidently believed to have been written by the late Robert Chambers. My father's copy gives signs of having been carefully read, a long list of marked passages being pinned in at the end. One useful lesson he seems to have learned from it. He writes: "The idea of a fish passing into a reptile, monstrous. I will not specify any genealogies--much too little known at present." He refers again to the book in a letter to Fox, February, 1845: "Have you read that strange, unphilosophical but capitally-written book, the 'Vestiges': it has made more talk than any work of late, and has been by some attributed to me--at which I ought to be much flattered and unflattered."), but have been somewhat less amused at it than you appear to have been: the writing and arrangement are certainly admirable, but his geology strikes me as bad, and his zoology far worse. I should be very much obliged, if at any future or leisure time you could tell me on what you ground your doubtful belief in imagination of a mother affecting her offspring. (This refers to the case of a relative of Sir J. Hooker's, who insisted that a mole, which appeared on one of her children, was the effect of fright upon herself on having, before the birth of the child, blotted with sepia a copy of Turner's 'Liber Studiorum' that had been lent to her with special injunctions to be careful.) I have attended to the several statements scattered about, but do not believe in more than accidental coincidences. W.
