by Mr. Charles Roeder, and also by Messrs. Brockbank and 

 De E-ance.* 



To Mr. Roeder we are especially indebted for our 

 knowledge of the fauna of these beds. 



With unwearied labour he examined and measured the 

 section inch by inch, washing the clays and marls, and 

 breaking up the thin limestones which occur all through 

 the section. The collection of fossils thus obtained was 

 forwarded by Mr. Eoeder to Messrs. Jones and Kirkby, and 

 others for identification, and the complete list was afterwards 

 published in the Society's Transactions. 



Mr. Roeder's collections were afterwards presented by him 

 to the Manchester Museum, Owens College, where I had the 

 opportunity and pleasure of working over them. 



The fauna of the lower productive measures at Ardwick is 

 chiefly known to us from the labours of Mr. Binney, who 

 published his results in the Transactions of the Society, 

 notably in Vol. YI. 



Mr. Binney' s work su:ffers from the free use of generalised 

 statements and the absence of specific determination of the 

 fossils. 



The character of the Upper Coal Measure deposits differs 

 in the upper portion very markedly from the rest of the 

 whole Coal Measure series. 



The succession of sandstones, shales and coals which we 

 regard as the dominant feature of the Coal Measures is
