Mr. Buckland on the 
APPENDIX. 
As connected with my present subject, I beg to subjoin a few 
valuable notices on the superficial gravel-beds of the midland 
districts of Rutland, Leicester and Buckinghamshire, by the Rev. 
W. D. Conybeare, with further important observations of other 
gentlemen on similar depositions of diluvian gravel. 
The gravel, accumulated in the midland counties of England, 
is considered by Mr. Conybeare to be a subject worthy of much 
more attention than it has hitherto received. These accumulations 
have been observed by him to extend over the plains that lie 
beneath the north-west escarpment of the great oolite chain, and 
also over the low tract between these hills and the north-west 
escarpment of the chalk of Bucks, Herts, and Bedfordshire ; but they 
are more particularly abundant in the former position, where extending 
many fathoms in depth, they often effectually conceal the subjacent 
strata, and sometimes by their accervation constitute decided hills. 
Tracts of this description are particularly abundant in the borders 
of Rutland, Warwick and Leicestershire. From Houghton on the 
Hill near Leicester, to Braunston near Daventry, proceeding by 
Market Harborough and Lutterworth, the traveller passes over a 
continuous bed of gravel for about forty miles ; near Hinckley, 
great depositions of gravel, probably connected with this mass, are 
found, and afford pebbles containing specimens of the organic 
remains of most of the secondary strata in England ; this deposition 
may probably be traced continuously to that of Shipston on 
Stour, most of the hillocks scattered over the lias and red marl 
tract between Southam and Shipston being crowned with this 
gravel.
