    Recommends Leonard Horner's "Account of some recent researches near Cairo" for publication in Philosophical Transactions [R. Soc. Lond. 148 (1858): 53–9]. Believes all the details and sections should be published in full because of importance of investigations leading to the conclusion that man has existed in Egypt for over 13000 years.

Dear Sir

Mr Horner's “Account of some recent Researches near Cairo” ought, in my opinion, to be published in full in the Philosoph. Transactions. Considering the importance of any investigation leading to the result that Man has existed in Ægypt for between 13,000 & 14,000 years, I think that all the details & sections, though given with great minuteness, should be published, as possibly being hereafter of great assistance to some future investigator.

Dear Sir | Yours faithfully | Ch. Darwin
To the Secy | Royal Socy

    This was the second part (Horner 1858) of Leonard Horner's paper on the alluvial deposits of the Nile basin. The first part (Horner 1855) had also been published in the Philosophical Transactions of the Royal Society of London, after being refereed by CD (see Correspondence vol. 5, letter to Leonard Horner, 18 [March 1855], and letter to the Royal Society, 19 March 1855).

    During the excavations, Horner had found a fragment of pottery at a depth of 39 feet. Assuming a rate of deposition of 312 inches of sediment per century, Horner calculated that man had lived in the Nile basin since 11,517 B.C. Horner's conclusions were later invalidated by the discovery of a Roman tile beneath the pottery shards (see Tristram 1860).
