372 Mr. Richard Taylor's Observations on 



most other cases^ bear but a small proportion to the sand ; they appear chiefly 

 in small fragments, few_, if any, perfect specimens bemg obtainable. 



No place along the course of the stratum that we have here traced, is so fa- 

 vourable to its examination as Bramerton, nor is there any, where its organic 

 remains are so abundant or so well preserved ; and accordingly its outcrop 

 at this place has supplied several naturalists, and in particular Mr. William 

 Smith and the late Mr. Sowerby, with excellent specimens of its fossils. There 

 are some species however, particularly those belonging to the genus Mytilus, 

 which, however perfect in form and colour, are too brittle to be taken out 

 entire. 



The accompanying sketch represents a section of the crag-strata, as they 

 actually appear at Bramerton, on the southern bank of the river Yare, resting 

 on the upper chalk. This is the deepest section in the county of the more 

 elevated strata. The annexed table contains the thickness of each stratum, 

 and a catalogue of the fossils is subjoined, both of such as I have observed 

 myself and as have been obtained by Mr. W. Smith and Mr. Sowerby. 

 Numerous as are the species, it is probable that many have escaped my obser- 

 vation ; and others have been purposely omitted, from my imperfect acquaint- 

 ance with their names and specific characters.
