1 In interpreting this and the following profiles the reader should bear in mind — (1) That the 

 proportionate thickness of the beds is not observed any more than convenience allows ; (2) the 

 relative thickness of the beds must be judged by the measurements, which do not claim to be more 

 than fairly accurate ; (3) the divisions shown do not in all cases agree with existing divisional planes ; 

 (4) the main object in all cases has been to emphasize the position of the chief beds bearing 

 ■Gasteropoda.
