Origin of Cyclones 23% 
Victoria, in 1857. It was afterwards communicated by the 
Astronomer-Royal to the London Philosophical Magazine, 
where it appeared in January 1859. A suggestion that I at 
the same time offered, that the opposite rotation of cyclones 
in the two hemispheres was due to the same causes as the 
westerly deflection of the trade-winds from a direct meridional 
course, has been generally adopted by physicists, and I am 
not without hopes that the main theory may also yet be 
accepted; but whether or not, I am confident that a study 
of the smaller eddies of air is the proper way to approach the 
difficult question of the origin of cyclones.
