Diurnal Tide at Cahercivebn — coiUinued. 



In discussing the Solar and Lunar Diurnal Tide involved in the preceding 

 Tables, by the method described in pp. 42-44, the following results were 

 arrived at: — 



I. — Diurnal Tide in Height at High Water. 



1. Maximum value of Lunar Tide for Positive Heights = 0-15 ft. 



2. Maximum value of Lunar Tide for Negative Heights = 0*20 ft. 



3. Maximum value of Solar Tide = 0'245; 



4. Diurnal SoHtidal Interval = 3" 28"'. 

 .5. Age of Lunar Tide = 5'^ 4\ 



II. — Diurnal Tide in Height at Low Water. 



1. Maximum value of Lunar Tide for Positive Heights = 0-23 ft. 



2. Maximum value of Lunar Tide for Negative Heights =0'30 ft. 



3. Maximum value of Solar Tide = 0245 ft. 



4. Diurnal Solitidal Interval = 3* 28"". 



5. Age of Lunar Tide = 4'' 17\ 



Adding together the first two of each of the preceding series of values, we 

 find
