Note: The means of the pressures in this table average lower than those given in vol. 79. A com- 

 parison of the monthly values with the pressure for the same month at Freetown indicates a sudden 

 change in the differences in 1924. Beginning with 1924 a correction of about +0.040 is needed to 

 reduce them to the level of the values previously published. This correction is not applied.
