116 SEVENTH REPORT—1837. 
feature differing essentially from those which are afforded by the 
discussions which I have already completed of the London and 
Liverpool observations. But it would certainly be desirable to 
determine the semi-menstrual inequality in the height at Brest, 
that is, the constants D and E; this may be done from a year’s 
observations. I determined some time since the semi-menstrual 
inequality in the interval for that place. See Phil. Trans. As 
the Brest observations extend throughout the same time as those 
of the London Docks which we have employed, the same tides 
might be discussed, and thus the influence of local circumstances 
and the resistances which the tide meets with in its progress from 
Brest to London might be clearly ascertained. I confess, how- 
ever, I am not sanguine that any advantage would now be gained 
sufficient to compensate for the great labour and expense which 
the discussion would require.
