VOL. Xv. (3) EXCURSION—-LECKHAMPTON HILL 187 
E. Strickland, however, in 1850 examined the section and found that 
besides the several recognised divisions being much greater than was 
thought they admitted of further division. Between the ‘‘ oolitic 
freestone,” that was ‘‘too fragmentary to be of much value for 
building,” and the Gryphite-Grit proper he noticed very fossilferous 
‘beds of brown rubbly Oolite, not employed for any purpose ” and 24 
feet thick. These intervening beds are now known as the Lower 
Trigonia-Grit and Buckmani-Grit. The Buckmani-Grit beds between 
the sand-deposit (13) and the Lower Trigonia-Grit are thicker than has 
been hitherto supposed—s feet 7 inches as against about 3 feet. 
The Gryphite-Grit was seen in a disused quarry on the hill-top by 
the side of the tram-line not far from the windlass. Farther south 
(on the hill-top) the junction of the Notgrove Freestone and Upper 
Trigonia-Grit was examined, and particular attention was paid to the 
top-bed of the former, which is remarkably well bored by annelids and 
less commonly by Lithophagi. Oysters were observed strewn over 
the planed surface. It was mentioned that a considerable thickness of 
beds was missing from between the freestone and the grit, but that 
some of them came in farther to the north on the Cleeve-Hill plateau. 
In order to show that there was no doubt that additional beds came in 
at certain horizons in the Inferior-Oolite Series, a visit was paid to 
Charlton Common, where between the Lower Trigonia-Grit and the 
Upper Freestone was seen clay—the Upper Snowshill Clay. 
An outline of the theory of River Development, which found so 
able an exponent in the Club’s former Hon. Secretary, MroS, ‘5: 
Buckman, was given by the Director and after some discussion the 
afternoon’s proceedings terminated.
