                                Petrified shell found in a hill near Huy (Belgium), communicated by Renatus Slusius to Henry Oldenburg in a letter dated 24 October 1668. This is most likely the drawing accompanying the original letter (EL/S1/56), and transferred to the Letter Book.

                                'I enclose the shape of one of them sketched (adumbratam) from either side, since the person who could make the sketch was at hand; only perhaps it was not so big. They are dug, I am told, five miles from here in a hill near Huum'. Correspondence of Henry Oldenburg, vol. 5, p. 90.
