MR. G. I. TAYLOR ON TIDAL FRICTION IN THE IRISH SEA 
8 :] 
energ}^ is found to be 1530 ei’gs 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 enei'gy 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.
