THE REV. W. WHEWELL ON THE TIDES OF THE PACIFIC, 
In the case of the recent observations I have given, not the “ establishment,” 
but the original observations, from which, of course, the establishment is to be de- 
duced. It is much more satisfactory to have the observations themselves than a 
conventional mode of expressing the result ; but the attempt to combine the two 
classes of data shows the difficulty into which we are led by this convention of an 
“ establishment” in the vulgar sense. For instance, at Port Bowen, the time of high 
water at new moon is 9'' 46“ ; but the interval at which the tide follows the moon 
varies from 37“ to ll'^9“. The mean of these, the corrected establishment, is 
9'* 53“ ; and in general the vulgar establishment is, as I have said, about 30“ greater 
than this, and therefore would here be lO** 23“. The great discrepancy of the 
establishment” obtained in these two different ways, arises from an anomalous 
course of the lunitidal intervals which appears in these observations, the mean 
interval being considerably removed away from the days of new and full moon. But 
the same discrepancy appears more or less in most cases. I combine the old and 
new observations as fairly as I can.

The tides at Port Essington will be the subject of more special consideration here- 
after. But I shall first consider the progress of the tide to the south side of Australia.
