STRATA OF IIOHDWELL CLIFF. 169 



9. White siliceous sand, without shells ; rises near Long-mead 

 End, and extends through Beacon and Barton Cliffs to 

 the middle of High Cliff.* 



Near Bournemouth, a little watering-place on 

 the Hampshire coast, between Hengistbury Head 

 and Poole Harbour, dicotyledonous leaves, in a 

 carbonized state, of the same species of plants 

 as those found in Alum Bay {ante, p. 162), occur 

 in a sandy marl, which traverses a cliff of firmly 

 aggregated white sand.-)- I am informed by 

 Will tarn Smart, Esq., of Cranbourne (to whom 

 I am indebted for many interesting specimens of 

 these fossil leaves), that the seam of marl is only 

 four inches in thickness, and is limited to a few 

 yards of the cliff, near the base ; it is about mid- 

 way between Bournemouth and Boscombe Chine. 



In addition to the fossils previously discovered, 

 Mr. Searles Wood has recently obtained the re- 

 mains of five genera of mammalia and of one 

 alligator, consisting of a jaw with all the teeth, 

 of lizards, serpents, and birds. The following 

 remarks on the geological phenomena observable 

 at Hordwell Cliff are too pertinent to be omitted :
