Notes on Jurassic Rocks, at Crickley read at a Meeting of the 
Cotteswold Club, March 20th, 1888. By W. C. Lucy, F.G.S. 
I have found it necessary in making this section to adopt 
the same course as I did for Birdlip, and have taken the hill at 
four different places. 
The entire length of the hill from No. 1 section at the 
W.N.W. end to the Air Balloon is 1170 yards. 
Commencing my description with No. 1, and taking the 
sands occur at an elevation of 780 feet, and are succeeded by 
the ammonite bed, which is highly ferruginous, and contains 
Ammonites ,Pleurotomaria, Gasteropods, and Trigonia ; and No. 2 
is a remarkably hard bed, full of shells, broken up like d reef 
detritus, with Pectens and joints of Pentacrinites, &c. 7 
No. 3 is also a hard fossiliferous bed, with numerous sponges 
Rhynchonella, Trichites, Serpula Socialis, Terebratuld and Belem- 
nites. ; : 
Bed No. 4is much of the same character, and in No. 5 the 
fossils are a good deal broken up, and consist mainly of Rhychon- 
ella, Pecten, Lima, Encrinites and small oysters. Here then is a 
break, and bed No. 6 is highly ferruginous, with Annelid borings, 
Belemnites, and numerous Pentacrinites, and is evidently the 
same as is met with at Huddingknoll Hill at the Horsepools, 
and at the section at Haresfield. 
No. 7 is stilla hard bed, and contains Perna, Trichites, Pecten, 
Ostrea, Serpula, Trigonia, Terebratula, and Rhynchonella. 
The section resembles a projecting bluff of rocks dipping 
from W.N.W. 7° to 12° to E.N.E., and is well shewn in the 
illustration enlarged from a photograph kindly made for me by 
Mr A. S. Helps, to whom and Mr Foster I am much indebted 
in assisting me at various times when I have visited the sections.
