2 EF. Loomis—Results from an examination of the 
weather maps of two years (1872-3) was 188. All the observa- 
tions made near the point of maximum pressure were rejected ; 
generally all the stations included with the first isobar. Also 
no observations were employed beyond the isobar 80 00, and 
generally none beyond the isobar 30°10. I then found by ad- 
dition the aggregate number of observations for each direction 
of the wind in the several quadrants, and from these numbers 
computed the wind’s average direction for each quadrant. The 
average velocity of the wind for each quadrant was also de- 
termined. ne following table shows the resulting velocities 
e 
which the wind’s direction makes with a radius drawn from 
the point of greatest pressure.

The importance of these results will be more apparent if we 
contrast them with the results obtained for areas of low barome- 
ter as given in my former article, pages 6-9. These results 
are as follows:

constructed the two following figures, in which the arrows.at
