Letter from J D [Joseph David] Everett, Derryvolgie Avenue, Belfast, to Lord Kelvin Everett wrote to Alexander Agassiz on 9 March 1896 after seeing his observations in the American Journal of Science and Art for December 1895. The letter followed Agassiz on his travels, catching up with him, perhaps in Boston, and Everett received a reply about 1 September. He has searched for this in vain, but replied to Agassiz on 14 September, keeping a memorandum, which he transcribes. In this, Everett refers to the cooling influence of water by thermal conduction through rock. He wrote to Agassiz that he intended to write about the Calumet and Hecla mines [Michigan] for this year's British Association, but he has not heard back from Agassiz. He has no further matter for the Underground Temperature Committee. With a note: 'Agassiz's paper enclosed'. 10 November 1897
