During the year under review, I was called upon to collect all the 

 available data of levels, existing in the Public Works, Eailway, and 



"Which differs from my determination by half a foot; but, if the tides at 

 Kejiri for February and March be alone taken into account, at which period the 

 inland waters flowing seaward are lowest, the result would agree with that 

 derived from my discussion of the tides at Calcutta to about one inch."
