Bespricht die Bohrversuche im Mersey-Kohlenfelde und in der 

 Nähe von Hobart. — Dort schreibt er: „It is probably pretty gene- 

 rally known now, that the seam of coal which has been worked 

 for many years past, in the Mersey district invariably underlies 

 certain marine calcareous beds, the presence of which was formerly 

 supposed to indicate that the base of the coal measures had been 

 reached. This feature is absent from the coal measures of the Eastern 

 and Southern districts and all such evidence, as is fortheoming leads 

 3ne to suppose that the latter belong to a later epoch than the Mersey 

 and. other districts bordering on the North Coast."
