The foregoing Tables show that a very regular Diurnal Tide exists at Port Kennedy. 
In order to compare the observed Tide with theory, we must compare the observed 
Tide, viz. : — 
A x cos s+B, sin s 
=a 0 +{ct 1 cos u-^~b 1 sin u} cos s 
+a 0 + {aj cos m+A sin u] sin s ....... (14) 
with the theoretical Diurnal Tide, viz. : — 
M' cos \-S' cos (s—i s ) (15)
