The lagging of the diurnal wave behind the semi-diurnal Phi 
at the Tortugas was 45, 23m, at the South West Pass is 45 49m, 
The mean computed depth of the portion of the Gulf traversed 
by the wave from the semi-diurnal wave is 1666 fathoms and 
from the diurnal 666 fathoms, for the mean result of the two 
1000 fathoms. The actual depth has not been ascertained, but 
probably does not exceed 1000 fathoms. From this line of deep 
water the semi-diurnal wave reaches the stations on the western 
coast of the Florida peninsula in their order from south to north 
and west. The movement west of St. George’s appears to be 
in the order of Pensacola, Fort Morgan, and Cat Island, while 
for the diurnal wave it was Cat Island, Fort Morgan, and Pen- 
sacola. At Sauth West Pass there is a sudden increase of esta 
lishment as if another semi-diurnal wave brought the tide there; 
the mean establishment of the six stations west of South West 
ass is 20h
