Austen

Devon limestones

Your referee is of opinion that the abstract in the Proceedings is sufficient to call the attention of Geologists to M^r Austen's views concerning the origin of the limestone of Devonshire. The principal facts, on which his views are grounded are there given,—namely the high inclination of the beds over a large area, & the presence of similar organic remains througout their entire thickness.— A paper of this nature, if it be not accompanied by detailed sections, & if great care be not evident in guarding against sources of error,—which is not here shown, for instance in the absence of all allusion to the possibility that the present flat surfaces of the limestone may have been caused by denudation, instead of being the effect of a coral-reef having reached the surface of the water,—a paper not thus accompanied, your referee thinks is not worthy of a place in the Transactions.—
