VOL. XVII. (i) INFERIOR OOLITE— SOUTH COTTESWOLDS 69 



Deutschlands," in which work the author draws the Une 

 between Lias and OoUte immediately below his Torulosus-Zone. 

 This is the present Moorei-aalensis deposit, so that it follows 

 that he considered the line of division between the Lias and 

 Oolite to come between the Moorei- and Dumortieria-Beds. 



On February 15th, 1859, Sir William V. Guise communi- 

 cated his valuable " Notes on the Inferior Oolite Beds in the 

 Neighbourhood of Bath.'" In it, he pointed out that the 

 Inferior-Oolite freestones of that neighbourhood, and of 

 Dundry Hill as well, were not equivalent to the Fimhria- 

 Stage as Lycett had suggested, but came above, instead of 

 below, the Upper Trigonia-Grit. Having made this important 

 correction, however, he fell into the error of correlating the 

 Inferior-Oolite freestones of the Bath district with the Dundry 

 Freestone, not noticing that whereas the former came above 

 the Upper Coral-Bed the latter came below. 



Wright, in his paper of i860, " On the Subdivisions of the 

 Inferior Oolite in the South of England, compared with the 

 equivalent beds of that formation on the Yorkshire Coast "" — 

 which marked a very great advance in our knowledge of the 

 Inferior-Oolite rocks of this country, and was an excellent at- 

 tempt to effect more widely-extended correlation — placed 

 2 feet 6 inches of " Intervening-Beds " at Rodborough Hill as 

 Gryphite-Grit, and i foot as Lower Trigonia-Gvit. His ideas 

 were no doubt somewhat influenced by Lycett, who held that 

 all the ' ' Intervening-Beds ' ' at Rodborough belonged to. the 

 Gryphite-Grit. As to the age of the Inferior-Oolite freestones 

 near Bath, he thought that they probably belonged to the 

 "upper subdivision," but was not very emphatic about the 

 matter. 



Dr H. B, Holl, in his paper " On the Correlation of the 

 Inferior Oolite in the Middle and South of England," overlooked 

 Sir William Guise's paper. As already remarked. Sir William 

 showed sufficiently-clearly that the Dundry Freestone and the 

 Inferior-Oolite Freestone near Bath, both belonged to a higher 

 horizon than Lycett had imagined. Holl also undertook 

 to point this out, and went further, attempting a more precise 

 correlation.^
