The enclosed plates and Photographs are representations of Fossils of the Forrest Marble clay found in a Cutting of the Wilts and Somerset Railway Southward & to the Westward of the Bridge carrying the road from Lacock to Corsham over the Railway – Some of these fossils are believed to be unique, or, but little known – as belonging to the Rock above named the Forrest Marble which generally consists of comminuted shells, crushed and condensed into a Mass sufficiently hard to take a good polish it is therefore only in clay beds between the layers of this Rock that shells in a state of good preservation can be met with and such a clay exists in the locality above named, and near Farleigh Hungerford still more to the S. W. –
