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.
