ARCTIC SEAS.— PART VII. PORT KENNEDY.

From (a) and (d) we obtain 
* 0’69Scos f,+ 0*4lM sin</>= — 117 (a) 
0'69S sin z‘ s — 0'4lM cos <j>— — 13'2 (d) 
Introducing the mean values of M and <f>, (42) we find 
S=36*4 inches 
7=45° 26'=3 h 2 m . . . 
(44) 
We thus find, finally, from the present and former calculations, 
Diurnal Tidal Constants. 
I. Hourly Observations. IT. High and Low Water Observations. 
M= 18*5 inches 
i m — — 2 m, 48 
S=36'4 inches 
i s =+ 3 h 2 m 
M=20'9 inches 
V= + 33 m *8 
S=23'4 inches 
V= + 5 h 12 m 
From the preceding values, it is evident, that the present more complete investiga- 
tion fully confirms my former conclusion, as to the unusually great magnitude of the 
Solar Diurnal Tide at Port Kennedy. 
III. Semidiurnal Tide. 
We must now calculate the values of A 2 and B 2 from the equations (9-14). 
We thus obtain 
Table V.— (A 2 ).
