In the preceding details a hurricane is regarded as a mass of air of a few miles or of several hundred miles in diameter revolving about a central calm. Storms of this kind are occasionally con temporaneous and so near together as to travel in almost parallel tracks. Instances have occurred in which the tracks of contemporaneous storms, instead of being parallel, have converged so as to approach, or to unite, or to follow each other on nearly the same track. There are also cases in which cyclones have started from points nearly on the same meridian but in opposite hemispheres, pursuing each its track, but revolving in opposite directions.
