I am very unwell, and incapable of doing anything. I do hope I have not inconvenienced you. I was so unwell all yesterday, that I was rejoicing you were not here; for it would have been a bitter mortification to me to have had you here and not enjoyed your last day. I shall not now see you. Farewell, and God bless you. Your affectionate friend, C. DARWIN. I will write to you in India. [In 1847 appeared a paper by Mr. D. Milne (Now Mr. Milne Home. The essay was published in Transactions of the Edinburgh Royal Society, vol. xvi.), in which my father's Glen Roy work is criticised, and which is referred to in the following characteristic extract from a letter to Sir J. Hooker:] "I have been bad enough for these few last days, having had to think and write too much about Glen Roy...Mr. Milne having attacked my theory, which made me horribly sick." I have not been able to find any published reply to Mr. Milne, so that I imagine the "writing" mentioned was confined to letters. Mr. Milne's paper was not destructive to the Glen Roy paper, and this my father recognises in the following extract from a letter to Lyell (March, 1847). The reference to Chambers is explained by the fact that he accompanied Mr. Milne in his visit to Glen Roy. "I got R. Chambers to give me a sketch of Milne's Glen Roy views, and I have re-read my paper, and am, now that I have heard what is to be said, not even staggered. It is provoking and humiliating to find that Chambers not only had not read with any care my paper on this subject, or even looked at the coloured map, so that the new shelf described by me had not been searched for, and my arguments and facts of detail not in the least attended to. I entirely gave up the ghost, and was quite chicken-hearted at the Geological Society, till you reassured and reminded me of the main facts in the whole case." The two following letters to Lyell, though of later date (June, 1848), bear on the same subject:--
