MR. G. I. TAYLOR ON TIDAL FRICTION IN THE IRISH SEA 33 



energy is found to be 1530 ergs per square centimetre per second. This is in good 

 agreement with the previous result. 



It is next shown that this absorption of energy is sufficient to reduce the amplitude 

 of the in-coming wave to one-half, so that three-quarters of the energy of the 

 in-coming tidal wave is absorbed. 



This absorption of energy explains most of the chief characteristics of the tidal 

 phenomena of the South Channel to the Irish Sea, the velocity of the co-tidal line, 

 which is only about one-third of the velocity of the tidal wave, the angle through 

 which the co-tidal line turns in passing up the channel and the effect of Carnsore 

 Point and Wicklow Head on the times of H. W. to the north and south of them.
