might be utilised in determining the total rainfall of Mauritius, it was

To this end the records of twenty-eight stations, situated in six

 it was observed that the curve is of a fairly regular nature, showing 

 .alternately an excess and deficiency of rainfall. 



The highest and lowest points of the curve will be gathered from the
