Charles Babbage, The Ninth Bridgewater Treatise (London, 1837). Appendix Note L. On Ripple Mark

"Mr. Lyell has observed and described this mode of formation of ripple on the dunes of sand near Calais; remarking, that in that case there is an actual lateral transfer; the grains of sand being carried by the wind up the less inclined slope of the ripple, and falling over the steep scarp. I have observed the same fact at Swansea."
