and, in a more fragmentary state, in the Isle of Wight, having a slope 
greater and in other directions. 
2. That while the gravel covering these tablelands at the highest 
levels is of a far greater age than the valley-gravels of the rivers, 
the gravel near Bournemouth, on Beaulieu Heath, Titchfield Common, 
and at similar levels appears to be equivalent in position and age to 
the high-level valley-gravels, and also to the beach-deposits of 
Avisford and Waterbeach containing marine shells; and that a 
lower tract of gravel bordering on the northern shore of the Solent 
and Spithead appears to correspond on the one hand with the low- 
level valley-gravels of the rivers, and on the other with the marine 
gravel covering the low land of Selsea. 
3. That the spreading out.of the gravel, and the levelling of the 
tablelands, probably was effected in an inlet of the sea shut in on 
the south side by land which connected the Isle of Wight with the 
mainland, and opening to the eastward. 
4, That a gradual upheaval appears to have gone on from the 
time of the oldest and highest gravels down to the date of the low- 
level valley-gravels, by which the inlet was narrowed into an 
estuary which received the waters of all the rivers from Poole Har- 
bour eastward, the Isle of Wight being still connected with the main- 
land. 
5. That of this upheaval in its latter stages there is evidence re- 
maining in the marine gravel of Sussex, in the raised shingle of the 
Foreland, and in the beach-deposits of Waterbeach and Avisford. 
6. That the flint implements of Bournemouth and Southampton 
Common are from gravel covering tablelands at elevations corre- 
sponding to the high-level valley-gravels, and that the implements 
from the coast between Southampton and Gosport are from gravel 
corresponding to the low-level valley-gravels. 
7. That the position of the flint implement found above the 
raised shingle of the Foreland appears to prove that an upheaval to 
the extent of 70 or 80 feet has taken place since its deposition in 
the brick-earth ; and that if the origin of the gravel covering the 
plains be as above supposed, the flint implements of Bournemouth 
show that the upheaval has been as much as 120 feet, and the im- 
plements in the gravel on Southampton Common as much as 150 
feet, since the appearance of man.
