the conclusion would fairly be drawn, that in Bohemia, as to the 

 west of the Pennine chain in England, there exists a full Permian 

 series, but with a different mineral-development from that of North- 

 ern Germany. 



Throwing out this hypothesis as a caution, I would only add that 

 the well-rounded pebbles of the coarse and fine conglomerates, which 

 compose the lowest member of the group, seem to me to have been 

 formed by the waves of a sea beating on the shore of an estuary, 

 adjacent to which exuberant forests prevailed, with trees like the 

 Arauearites and Guc/Uelmites, which must have required a genial 

 if not a warm climate to bring them to their large dimensions. 

 When we also consider that these water-worn sediments are at 

 intervals interlarded with outpourings of igneous matter, in the 

 form of porphyries, basalts, tuffs, and amygdaloids, we have before 

 us nearly all the material data for speculating upon the condition of 

 large portions of the surface of the northern hemisphere at the close 

 of the Palaeozoic era, and antecedent to the origin of those new orders 

 of Animals and Plants which began to prevail in Mesozoic times.

1. On the Correlation of the several Subdivisions of the Inferior 

 Oolite in the Middle and South of England. By Harvey B. 

 Hole, M.D., F.G.S. 



(Abridged.) 



Introduction. — The Inferior Oolite in the South of England compre- 

 hends two well-defined subdivisions ; namely, an upper member, 

 consisting of light- coloured, coarse-grained, more or less thin-bedded 

 or flaggy oolite, containing few fossils, and those chiefly in the form 

 of casts ; and a lower member of hard, brown, ferruginous lime-rock, 

 often much speckled with ovoid grains of peroxide of iron, and 

 abounding in fossil remains. The relationship which these two beds 

 hold with respect to the other members of the Inferior Oolite has 

 been differently viewed by geologists. 



The late Mr. Strickland evidently regarded the lower brown fos- 

 siliferous limestone as the equivalent of the Cephalopoda-beds of 

 Haresfield Hill*. 



On the other hand, Dr. Lycett, referring to the same bed at 

 Dundry, remarks that, " considering the position of the Mollusca- 

 bed beneath the Freestones, and overlying the Cynocephala-stage, it
