from hence, and could be observed in the whole course of 

 this morning's walk, proceeded by the turnpike road to 

 Calne, where they took the rail for Bath, and arrived at home 

 after a second day of much interesting and instructive 

 investigation. 



The Second Excursion for the season was made on May 

 28th, to Camel and Cadbury Camp. Ninteen Members mth 

 their friends, amongst whom was the Dean of Ely, left Bath 

 at an early hour for Sparkford Station, walked down the hne 

 to the cutting which runs through the quarries, and, seated 

 beneath the shade of the bridge which forms a fine span 

 across the Hne at this point, spent a pleasant half-hour in 

 listening to Mr. Charles Moore's description of the section 

 before them. 



Referring to his paper lately read before the Geological 

 Society in London, in which the details of the various beds 

 are fully given, he alluded to the important effect which the 

 uplifted range of the Mendip Hills had in altering the 

 characteristic features of the secondary deposits to the north 

 and south of that range. The thickness of the deep-sea 

 deposits on the south being vastly greater than the correspond- 

 ing beds to the north of the barrier — e.g., the lower lias alone, 

 which is 700 feet thick without the coal-basin, being reduced 

 to 2 feet within. With more especial regard to the cutting 

 in which they were assembled, consisting of a succession of 

 260 beds, with a thickness of 275 feet, Mr. Moore described 

 the various physical and palseontological pecuHarities of each 

 bed, from the Keuper marls of the new red sandstones at the 

 base on the south, ranging up through the Rhoetic clays to 

 the white lias and Mr. William Smith's " sun bed" (the top- 

 most bed of the Rhoetic series) and onward in ascending order 

 to the blue Has proper up to the lower horizon of the lower Has. 

 Every bed almost, after passing the Keuper marls (which are 

 singularly destitute of organisms, and are probably a brackish
