* The shells, &c. of the Selsea Beds are chiefly derived from marine mud, in which Elephas 

 primigenius has also heen found. It lies partly on irregular patches of red sravel, and is 

 overlaid by yellow clayey gravel with ice-scratched stones (chalk, flints, &c.) and large erratic 

 blocks of granite, &c. Above these boulder beds there are beds oi sand and gmvel whicli 

 also contain sea shells. It is overlaid by brick earth. — A. C. R.
