I have examined the lime-stonfeabout Sunderland, and can only refer myheaders to Mr. Bakewell’s treatise on thegeology of England * for a more explanatoryaccount. Dr. Clanny made some very in-teresting investigations on a lime-stone rock inthe vicinity of Sunderland containing marineimpressions, and which Mr. Bakewell is in-clined to consider of subsequent formation ; Dr.Clanny communicated the result of his in-quiries through the medium of Thomson’sAnnals, in August, 1815.

Various specimens of the different stratamay be examined on the coast, as the perpen-dicular aspect affords a complete section of thewhole. In some places near Sunderland thereappears to have been a sinking in of the strata,as the parallelism is destroyed, and one seriesdips to the south-east, while the other dipsnorth-west, and giving passage to water in theline of their junction. (See plate III.)

The lime-stone formation contains the im-pressions of fish to a large extent, and variousother productions of the sea.
