That many individuals engaged in mining operations 

 possess much valuable information respecting the Coal Strata 

 of Yorkshire, there can be little doubt ; but with the excep- 

 tion ^f two or three short, but valuable essays, in the Trans- 

 actions of this Society, and some observations in the 

 Encyclopcedia Metropolitana, I know of no other published 

 account of the extensive and valuable Coal Formation of 

 Yorkshire. Under such a state of our knowledge, a series 

 of short observations from various localities, drawn up 

 according to some stated formula, and printed in the Trans- 

 actions of this Society, would be of the highest value. 



Mr. Briggs exhibited and explained that portion of the 

 line of section, comprehending the township of Thornhill

Mr. Holt exhibited and explained that portion of the line 

 of section, comprehending the townships of Clifton and 

 Hartishead. 



Dr. Inglis exhibited two specimens of Nautili from the 

 Halifax coal strata.
