MR ROBERT KIDSTON ON THE 



Last year Mr Meachem kindly gave me the opportunity of examining the fossils 

 collected during the sinking operations at Great Barr, and the Upper Coal Measure 

 fades of many of the specimens is very pronounced. I revisited Hamstead Colliery this 

 year, and went more carefully over the specimens. Mr Meachem diligently collected 

 examples of all the fossils met with during the sinking of the shaft, and at the same 

 time noted at what depths they occurred, and the nature of the beds in which they were 

 contained. The whole of this collection was most kindly placed at my disposal for 

 determination and description. Mr F. G. Meachem has further favoured me with the 

 details shown in the following section, which give the general character of all the beds 

 from which the fossils were derived, as well as the thickness of the beds, and the depths 

 at which they occur.
