2. On the Occurrence of Mammalian Remains at Brentford. 



By John Morris, Esq., F.G.S. 



The discovery of mammalian remains in the vicinity of Brentford 

 has long been well known to geologists. It is more than thirty years 

 since Mr. Trimmer obtained a valuable collection from this district. 

 An account of these remains and of the conditions under which they 

 were found, was published with illustrations in the 'Philosophical 

 Transactions ' for 1813. In 1838 I collected from an excavation, for 

 the reservoir of the water-works near Kew Bridge, numerous horns 

 and bones of the ox and deer, and bones of the elephant ; traces of 

 lignite also, but no remains of shells, were observed. I should not, 

 therefore, have laid before the Society the following remarks, had not 

 the progress of the railway-works in that neighbourhood exposed 

 some sections, which not only fully corroborated previous observations, 

 but afforded some new facts connected with the history of the deposit, 

 as well as a considerable number of mammalian bones, for the pre- 

 servation of which we are indebted to the active zeal of Mr. Thomas 

 Lay ton, jun. 



The sections alluded to occur about 100 yards north of Kew 

 Bridge, where a branch or rather loop line of the South- Western and 

 Windsor Railway passes under the high road at the entrance to 

 Brentford. The section here given occurs north of the bridge, where 

 the entrance to the station is completed. 



This section gives the principal features of the deposit, as exposed 

 in the deepest part of the railway cutting, which extended about one-
