DOVE ON THE LAW OF STORMS. 203 
| land and Iceland are on the north-western side, and England is 
nearly in the middle of its course. 
On the supposition of a centripetal inflowing according to 
Brande’s view, as the 
phzenomenon passes over 
a station on the south- 
eastern side, a wind vane 
at that station should be 
seen to pass successively 
from E.N.E. through E., 
E.S.E., S.E., 8.S.E. and 
S., to S.S.W.; and ata 
station on the north-west- 
ern side the vane should 
pass from N.N.E. through 
f WY N., N.N.W., N.W., W. 
eget vee N.W. andW., to W.S.W. 
(Fig.1.) If, on the other hand, the storm is rotatory and turning 
in the opposite direction to that of the hands of a watch, the wind 
Fig. 2. at a south-eastern station 
will pass from S.S.E. 
throughS.,S8.S.W.,S.W., 
W.S.W., and W., to 
- W.N.W.; and ata station 
onthe north-western side, 
from E.S.E. through E., 
E.N.E., N:E., N.N.E., 
N. and N.N.W. (Fig. 2.) 
At places situated in the 
middle of the phenome- 
non the wind should 
change suddenly, accord- 
ing to the first view, 
from N.E, to S.W.; and, according to the second view, from 
S.E. to N.W. 
Both suppositions agree in leading us to expect a rotation 
with the sun on the south-eastern side of the storm, and against 
the sun on the north-western side; and in the middle a calm, 
dividing winds blowing in opposite directions; but they disagree 
in making a difference of 90° in the two opposite positions of 
the wind vane at the commencement and at the termination of 
the rotation.
