182 Reports and Proceedings. 



Devonian to beds containing undoubted marine fossils, lying be- 

 tween the top of the Old Eed Sandstone and the base of the Coal- 

 measures. Taking their wide range over the world into account, he 

 would even regard the Devonian rocks and fossils as the most 

 general type of that portion of our series, and consider the Carbo- 

 niferous Limestone of the British Islands and Belgium as the local 

 and exceptional peculiarity. 



The following specimens were exhibited : — Pterygotus, Stylonurus, 

 Eurypteriis, and GepJialaspis, from the Old Eed Sandstone of Forfar- 

 shire ; exhibited by James Powrie, Esq., F.G.S. Encrinus monili- 

 formis, from the Muschelkalk, Saxony ; exhibited by E. Charlesworth, 

 Esq., E.G.S. Mineral oils and rocks associated with them from 

 Pisa ; presented by St. John Fairman, Esq. Specimens of ' Wood- 

 wardite,' a new mineral from Cornwall ; exhibited by Bernard H. 

 Woodward, Esq. A miscellaneous collection of rocks; presented 

 by W. T. Black, Esq. 



Liverpool Geological Society. — March 13th, 1866. H. Duck- 

 worth, Esq., F.G.S., F.L.S., the President, in the chair. The fol- 

 lowing papers were read: — "The Mineralogical Characters of Eocks," 

 by Mr. F. P. Marratt. " The Geology of the neighbourhood of St. 

 David's, Pembrokeshire," by Mr. E. A. Eskrigge, F.G.S. "The 

 Coal-fields of Flintshire and Denbighshire," by Mr. Edward Nixon, 

 Mining Engineer. 



The latter communication was elucidated by a section of the Coal- 

 measures of the district around Mold. The author expressed his 

 opinion that the Coal-seams of North Wales were continued under 

 the New Eed Sandstone of Cheshire, and that the time is not far 

 distant when means would be adopted to prove the fact. So far as 

 the Coal-seams could at present be correlated with those of Lanca- 

 shire, the beds worked in North Wales appear to represent the 

 central portion of the middle productive measures. The upper and 

 lower part of the series are not clearly developed, though it is 

 probable that the whole Coal-series occur in the neighbourhood of 

 Mold, and along the border of the river Dee. The Main Coal is 

 considered to represent the Wigan, nine-feet ; but there is no bed 

 worked so low as the Arley Mine of Lancashire. Eeference was 

 also made to the oil-producing cannel and associated shale at Lees- 

 wood, Coed Salon, and Coppa Collieries, where over one thousand 

 retorts have been erected, showing the importance and wealth of the 

 district. 



Mr. T. J. Moore exhibited a fine series of the bones of the Dodo, 

 from the Mauritius, collected and presented to the Liverpool Museum 

 by Mr. Henry P. Higginson. — G. H. M.

 sazione and Exhibition of objects of scientific interest was held at
