The foregoing section is of the greatest interest, as it forms 

 one of the best evidences yet obtained regarding the strati- 

 graphic relation of rocks of the Fingal basin. The 

 particulars were most carefully tabulated by Mr. Bateman 

 at the close of each day, and may, therefore, be depended 

 upon as being fairly accurate. 



It is clear, although, unfortunately, no important coal 

 seams were met with, that the lower coal measures exist in 

 this district below the Fenestella limestones and mudstones 

 of Upper Palaeozoic Age, and the existence of a very thin 

 coal seam together with shales containing plant impressions 

 akin to the Schizoneura and possibly Gangamopten's of the 

 Mersey District indicate that the beds are probably the 

 equivalents of the lower coal measures of the Mersey. It is 

 of interest to observe also that the Mersey coal measures 

 also repose upon Silurian rock, although in the latter district 

 limestones are probably of Lower Silurian Age.
