stratum separate, and distinguishing the now named ' Upper and Lower Ludlow 

 rocks ' by the names of ' Grauwacke and Pendle ' (the latter being the local 

 name) ; and the Aymestrey and Wenlock limestones by Pentamerus, and Coral 

 or Nodular limestone ; the former from its abounding in the Pentamerus Knightii ; 

 and the latter from its great richness in corals, and the appearance which its 

 weathered beds assumed in this neighbourhood, even where they were con- 

 sidered worth working for the kilns. I had very soon a collection, ex- 

 tending from the junction of the Old Red Sandstone with the Grauwacke, 

 down to the Wenlock Shale (or nodular strata), and had fairly traced these beds 

 westward and eastward, to the full extent of this parish, T829 ; and along 

 the prolongation of the Croft Ambrey and Gatley escarpments towards Ludlow ; 

 and in the outliers of Tinker's Hill and Cainham Camp, on the other side of the 

 river Teme, in the direction of the Clee Hills ; and likewise in the neighbourhood 

 of Leintwardine." 



The Edinburgh Review, when treating subsequently of the Silurian system, 

 and speaking of Mr. Lewis's labours in this district says, " We have had the 

 pleasure of examining a part of that beautiful and instructive country under his 

 guidance, and are thus enabled to give personal testimony to his exact acquain- 

 tance with its structure ; and not less cordially to the frankness and absence of 

 pretension with which his knowledge is communicated. And we are satisfied 

 that Mr. Lewis was the first person to ascertain that a series of what were called 

 transition rocks, succeeds, conformably, to the Old Red Sandstone at Ludlow ; 

 to distinguish the groups of strata by many of their principal fossils ; and to prove 

 that in the tract immediately adjoining Aymestrey, and on the south of Bringe- 

 wood chase, the strata, though thrown up and much disturbed, exhibited every- 

 where the same determined order of succession." 



Sir Roderick Murchison, in his great work, The Silurian System (of which, by 

 the bye, a third edition is announced by Mr. Murray), refers to the great assistance 

 afforded him by Mr. Lewis's earlier labours. In treating of the now world-famed 

 " Aymestrey limestone," he says he named it " after the beautiful village of 

 Aymestrey, where the rock is fully and clearly laid open, and where its fossils 

 contents have been elaborately worked out by my friend the Rev. T. T. Lewis." 



It may appear superfluous to enlarge upon this point, or to say that the 

 fossils named after Mr. Lewis (as the Lingula Lewisii, Cephalaspis Lewisii, Spiror- 

 bis Lewisii), must prepetuate his name in the mind of every student of Geology ; 

 but the " absence of pretension " which the Reviewer speaks of, and the love of 

 retirement, prevented Mr. Lewis from taking that position before the public to 

 which his talents and knowledge entitled him. He loved knowledge and science 

 for their own sake, and cared not to have his name associated with this or that 

 society. Nevertheless, he maintained an intimacy and correspondence with some 

 of the most distinguished men of the day, especially in that field of knowledge to 

 which his attention had been early directed, and with which he kept pace, not- 

 withstanding that the circumstance of his appointment to the living of Bridstow 

 withdrew him from Siluria propria.
