 The pure bole is rarely many inches thick. In some cases it is very 

 markedly affected by a system of prismatic jointing on a small scale ; 

 but, unfortunately, the mass is so friable that it is impossible to collect 

 any of the very pretty little prisms ; they crumble under the most 

 delicate handling. 



From the circumstances under which they occur, from their limited 

 extent, and from their strong lithological resemblance to the unquestion- 

 ably fresh-water deposits among the lower flows of the Deccan trap, 

 the infra-trappean beds may, in the absence of any more positive evidence, 

 be fairly set down as of lacustrine origin.
