Extract

Shropshire was always considered by Sir Roderick Murchison as one of the districts in which his Upper Silurian rocks could be most advantageously studied.1 We propose, therefore, in this communication to offer some few notes on the Geology and Palæntology of the Wenlock and Ludlow series; illustrated by the Brachiopoda, reserving for the present what we may have to communicate with respect to the Upper Llandovery.

page 100 note 1 We follow Sir Roderick Murchison's classification of the Lower Palaeozoic formations, for no geologist worked harder to unravel the complications under which the Upper and Lower Silurian rocks were shrouded. The publication of the “ Silurian System” in 1839, with all its imperfections and on the model of Smith's “ Strata identified by Organized Fossils,” did more than any other work to stimulate researches in the right direction all over the world.
