168 Miscellanies, 



2dly, The broken and rolled state of the greater part of the 

 bones, the pebbles, and the conglomeritic character of many of the 

 deposits, prove that the strata were formed in the bed of a river, or 

 an estuary. 



3dly, It is equally obvious, that the Hastings, or Tilgate strata, 

 must have been formed and consolidated before the chalk, which 

 rests upon and once covered them, was deposited. It follows, that 

 after the Hastings' beds were formed, they must have been sub- 

 merged beneath the ocean which deposited the chalk formation ; for 

 the latter, as we shall presently shew, contains nothing but marine re- 

 mains, and not one fossil of the Hastings' beds. 



4thly, The ocean of the chalk, in its turn, must have passed away, 

 and the consolidated chalk have been covered by the waters which 

 deposited the tertiary strata, for the latter contain fossils entirely dis- 

 tinct from those of the chalk. 



Lastly, The tertiary, in common with the chalk and Hastings' beds, 

 must have been subsequently broken up, probably by volcanic agen- 

 cy, and the wealds of Kent and Sussex formed, and the chalk dislo- 

 cated and separated, by the upheaving of the central strata of the 

 Hastings' formation : the lateral fissures in the chalk now constituting 

 the vallies, through which the existing rivers flow, and effect the 

 drainage of the country. To this epoch may probably also be refer- 

 red the formation of the beds of diluvium. 



Case III. — With but few exceptions, the fossils in this Case are 

 not from Sussex. 



Shelf 1. Teeth of Elephants, from the diluvial beds forming the 

 cliffs at Brighton and Rottingdean : horns of Aurochs, fragments of 

 the anders of the fossil Elk of Ireland, &;c. 



2. Tusks of elephants, horns of buffaloes and aurochs, k,c. from 

 Walton, in Essex, presented by G. B. Greenough, Esq. Shoulder- 

 bone, (scapula,) of a Mammoth, from North America. 



3. and 4. Teeth and bones of mammoths, rhinoceroses, croco- 

 diles, plates of turtles, fossil vegetables, &c. from the diluvial plains 

 forming the banks of the Irawadi river, two hundred miles below Ava, 

 in the Burmese Empire. Collected and presented by J. Craufurd, 

 Esq. F. R. S. 



5. Remains of Iclithjosaurl, from Lyme Regis ; skull of the ex- 

 tinct fossil bear, (Ursus spela^us,) from the caverns of Gaylenreuth ; 

 bones in limestone, from Gibraltar j tooth of a mammoth, from Sibe-
