Hupteston, who treats of Bagshot Beds and Gravelly Drifts, and 
criticizes the Geological Survey mapping and classification of 
the beds at St. Anne’s Hill, near Chertsey. 
In this year appeared that very useful work, the Geologists’ 
Association’s ‘Record of Excursions,’ during the years 1860 to 
1890. Of this pp. 74 to 114 are devoted to Surrey, the places 
mentioned in the titles being Addington, Box Hill, Caterham, 
Chilworth, Croydon, Dorking, Epsom, Godstone, Guildford, Kew, 
Kingston, Leith Hill, Mole (Valley of), Nutfield, Redhill, Rich- 
mond, Riddlesdown, Shirley, and Tilburstow. 
In “ Physical Studies of an Ancient Estuary,’* Dr. Irvine 
treats of the Bagshot Beds of the London Basin generally. 
J. T. Harrison’s paper ‘‘On the Subterranean Water in the 
Chalk Formation of the Upper Thames, and its Relation to the 
Supply of London,”’} deals, of course, with Surrey, including 
some parts that can hardly be described as connected with the 
Upper Thames, such as the Basin of the Wandle, with a map of 
its Chalk gathering ground (pp. 5, 7-10). Other references to 
Surrey are to be found on pp. 12, 14, 15, and in the discussion, 
on pp. 26, 31, 52-57, 60, 63, 64, 67, 71, 73-75, 85-87, 96, 98. 
T. Lereuton, in the abstract of his paper ‘‘On Recent Dis- 
cussions relating to the Geology of the South-East of England,’’} 
refers to the Bagshot Question, to the Sands of doubtful Age on 
the North Downs, and to Coal in South-East England. The 
first he describes ‘‘as an attempt to establish certain uncon- 
formities which do not exist,’’ in which many geologists will 
agree with him; but the other two are left as open questions. 
1892. 
H. W. Monoxron’s paper ‘‘On the Gravels south of the Thames 
from Guildford to Newbury’’ § refers partly to Surrey. 
‘«* The greater part of the hill-gravel . . . belongs to the Southern 
Drift of Prof. Prestwich,” which consists ‘‘ of materials derived 
from the Wealden area of Kent and Surrey, the Chalk... Hocene 
formations ...and older gravels.” The author thinks it to be 
‘‘the gravel of old rivers which had little or no relation to our 
present river-system.’’ The gravel of Chobham Ridges and the 
Fox Hills is an example of this Drift. 
The gravels of the valleys and terraces are of local origin, and 
largely derived from the older gravels. 
The same author also gave a paper on “ The Bagshot Beds of 
Bagshot Heath,’’|| which is concerned with a controversy as to
