Diurnal Tides of the Coasts of Ireland.

Caherciveeii Tide, Table F. 



Difference of observed and calculated times of vanishing at low 



water, expressed in lunar days. 



Age of lunar tide = 4*^ 17*^. 



The agreement between the observed and calculated heights 

 and times shown in the preceding Tables, is as close as can be 

 expected in tidal observations, and indicates the degree of import- 

 ance which should be attached to the diurnal tidal constants at 

 Caherciveen. 



Section V. Diurnal Tide at Bunown. 



Separating the solar and lunar tides in the diurnal tide at 

 Bunown, deduced from the observed heights by the method 

 already described, I obtained the following results : — 



I. Diurnal tide in height at high ivater. 



1. Maximum value of lunar tide for positive heights =0'20 ft. 



2. Maximum value of lunar tide for negative heights = 0'28 ft. 



3. Maximum value of solar tide =0"25 ft. 



4. Diurnal solitidal interval = 2'^ 52i». 



5. Age of lunar tide =4*^ O'^, 



II. Diurnal tide in height at loio tvater. 



1 . Maximum value of lunar tide for positive heights =0*30 ft. 



2. Maximum value of lunar tide for negative heights = 0*40 ft. 



3. Maximum value of solar tide =0*25 ft. 



4. Diurnal solitidal interval =2^ 52'". 



5. Age of lunar tide =4'' 9''. 



Adding the first two of each of the preceding, we find — 



Range of lunar tide at high water =048 ft. 

 Range of lunar tide at low water =0*70 ft.
