Arr. XX XIII.—On the Tides at Key West, Florida, from obser- 
vations made in connexion with the United States Coast Sur- 
; D 
; ceedings of the American Association for the Advancement of 
- Science. (With six Plates.) 
ourLy observations of the tides were made at Fort Taylor, 
West, from the Ist of June, 1851, to the 31st of May, 1852, 
Mr. J. W. Goss, of the Coast Survey and assistants. ‘The 
Waters may differ is very important. The corrected establish- 
ent of Key West is 9h. 22m. The curves of Plates 1, 1 bis, 
2, 3, 4, and 5, show the normal character of the tides at the 
ximum and zero of the moon’s declination at the syzigies and 
ures, and ata mean of declination and six hours of the 
. age. There being two tides in the lunar day, the obser- 
tions admit of discussion by the ordinary methods, while the 
diurnal inequality in height of high water renders it desira- 
to pursue the mode which I have applied to the tides at Cat 
roughont this paper the whole difference of the A.M. and P. M. tides. is 
diurnal inequality.
