The Rev. Samuel Haughton on the Solar and Lunar 



It appears from the preceding investigation, that the maximum effect in rais- 

 ing or lowering the sea, produced by the Diurnal Tide at Castletownsend, is, 



0-181 ft. X sin 42° = 0-1 17 ft. = 1-4 inches, 

 the total effect both ways being less than three inches ; consequently the water 

 will be raised 1-4 in. when the Moon has crossed the meridian l* ll", and de- 

 pressed by the same amount when the Moon has crossed the lower meridian 

 1" 11"'. 



It is not surprising that it should be difficult to separate such a small effect 

 as this into a Solar and Lunar Tide.
