act in an exactly opposite direction upon their course, hence the 
rotation of the wind round Anti-Cyclones is in a contrary direction 
to that of Cyclones in the same hemisphere. 
: _ In conclusion, let me quote one of the golden rules in meteor- 
ology. “Wind a/ways blows from where the air pressure is high 
to where it is lower,” as water always runs down hill, and fora 
somewhat similar reason.
