In passing upward through the Chalk from the 



basemenl bed ol the impure Chalk Marl, it is to be 



d that analyses of Chalk taken from the various 



beds would differ to some extent as t>' the percentage 



onate of lime, which each specimen contained. 



Iii two analyses made by Professor I. T. Way of
