96 TIDES AND BENCH MAEKS 



Prom this table it appears that the mean level of the sea is most depressed 

 in the latter part of January, and most elevated in September. This change 

 in mean level is presumed to be due to meteorological conditions, such as varia- 

 tions in barometric pressure and resultant wind directions and velocities. 



In conclusion, it may be remarked that the type of tide at Nassau is that 

 of the Atlantic coast of the United States, and not at all like the tides in the 

 Gulf of Mexico.
