the Inferior Oolite into three zones, whereof he styles the lower the 

 zone of Ammonites Murchisona ; the middle the; zone of Ammonite* 

 Humphresianut ; and the upper the zone of Ammonites Parkinsoni ; 

 these subdivisons having different degrees of development in different 

 parts of the counties of Gloucester, Somerset, and Dorset, being 

 thick, thin, or absent, as the case may be. The upper zone is, he 

 states, the most persistent throughout England, France, and Ger- 

 many. The middle zone is only feebly represented in the northern 

 Cotteswolds, but fairly developed at Dundry ; the lower zone having 

 its best development near Cheltenham. 



The Charlcombe and Limpley Stoke beds near Bath, are referred 

 by the Doctor to the upper zone, the middle and lower zones being 

 absent. 



For a more ample and complete exposition of Dr. Wright's views 

 upon this subject, I would refer enquirers to the very learned paper 

 upon "The Subdivisons of the Inferior Oolite in the South of 

 England," read before the Geological Society, in April, 1859, and 

 now published in the February number for the present year of the 

 Quarterly Journal of the same Society. It is a masterly resume* of 

 the entire subject, conducted with admirable patience and research, 

 and illustrated by an amount of learning both literary and paheon- 

 tological, which must ever render the paper indispensable as a work 

 of reference to all students of the Oolitic Series, whether they accept 

 the Doctor's limitations and subdivisions or not 



May 11. The Club met at the "Lamb Inn," Cheltenham, and 

 mustered in considerable force. After breakfast, an omnibus con- 

 veyed the party to the foot of Cleeve Hill, where the Geological Sec- 

 tion, under the direction of the late President, and Messrs. Brodie, 

 Norwood, and Jones, proceeded by the lane which passes between 

 the " Rising Sun " and Mr. Dobell's residence at " Cleeve Clouds," 

 to investigate the stratigraphical position of the so-called " Road- 

 stone" of the district, the characteristic fossil of which is Terebratula 

 Phillip&ii. While the Entomological Section, represented by the 

 President, and the Rev. T. A. Marshall, took the lower ground 

 through the village of Bishop's Cleeve. 



To the Secretary, I am indebted for the following account of the 

 proceedings of the Geologists, and for the very valuable list of fossils 

 annexed, of which few could have furnished so ample and reliable 

 a catalogue : 



These beds those containing the "Roadstones" are clearly 

 much out of place, and must, when "in situ," have been superior 

 to those of the Fimbria Stage, which now cap the hill immediately 

 above them Previously to having seen them, the Secretary, from 

 the account given of their fossil contents by Messrs. Norwood and 

 Bromby, ventured to assign to them a stratigraphical position, and 

 the subsequent examination of their organic contents, as well as of 

 their lithological characters, confirmed him in the opinion he had 

 expressed ; namely, that these beds are the equivalents of those, 

 which at Ravensgate, Cooper's Hill, and Haresfield, immediately
