Possible Lunar Influence upon the Velocity of the Wind at Kimherley. 179 
Column 3 gives the means of the deviations when the moon near apogee 
culminates between IX and XY. 
Column 4 the same for culminations between XXI and III. 
Column 5 the same for the remaining hours. 
These "noon" and " midnight " culminations have been extended over 
a six-hour range, instead of over the four-hour range (X to XIY, and XXII 
to II) used for perigee terms, in order to give a larger number of observa- 
tions for discussion, and so smoother curves, for those culminations. But 
of course such an extension of the time limits must impart something of the 
" horizon " character to the " noon " and " midnight " curves deduced. 
As before, all the tabular numbers have been smoothed in threes. 
The curves shown in the diagram are best studied by comparison with 
the perigee curves of the second paper. C-enerally they show the same 
turning-points as the perigee curves, but somewhat lagging, and the 
moonrise minimum is not so pronounced, e. g. :
