Abstract
During the past twelve months I have devoted much time to the careful study of those questions that relate to the probable source of derivation of the sandstone and quartzite boulders or “pebbles” that were drifted and accumulated in the neighbourhood of Budleigh Salterton by “Bunter” waters. The detailed results of my investigations will appear in my forthcoming Devonian Supplement. Cornwall and North Devon having been pointed at, as a probable source of derivation, I considered it necessary to study the rocks and fossils that exist in those portions of Great Britain, as well as those that occur in Normandy and Brittany, on the other side of the Channel.
