side of the compass be added together, it will be seen that 
the sum of the degrees on the East side is 1080, whilst the 
sum of the West side is 1300, showing a ratio of excess of 
the West side over the East of 12 . But if the degrees for 
each of the 8 points on the East side be added to the degrees 
of each of the 8 points on the West side the following result 
appears ; —

The maximum of these numbers of degrees is found in 
the East and West, both severally and conjointly, and the 
minimum in the same way in the SSE and NNW. This 
seems to show that the equatorial currents take a much 
wider sweep over the earth than the polar currents do, or 
rather that their oscillatory waves are more extensive. 
I have, below, reduced the number of degrees through 
which the wind has veered to the four cardinal points, and 
they appear as follows : —

This shows that the oscillation increases in the direction 
of the sun’s course, and attains its maximum at the West 
point, or rather between the South and the West, thus that 
the maximum of wind frequency is similar in position to its 
maximum of oscillation. 
The following table represents the ratio of the advance 
which the veering of the wind made with the sun’s course, 
against its retrogression for each of the given 1G points of 
the compass : —
