To the Royal Society   19 March 1855


I am of opinion that Mr. Horner’s Account of the researches made in the alluvial deposits of Ægypt, should be printed in the Philosophical Transactions,1 as the means of permanently recording valuable observations; and which observations probably will become in future times of still higher value.—

Charles Darwin Down  March 19th. 1855.

Recommends publication of Leonard Horner’s account of researches in alluvial deposits of Egypt [Philos. Trans. R. Soc. Lond. 145 (1855): 105–38]. It contains valuable observations which will probably become of still higher value in future.
