640 hour, or, compared with that at the level of the sea, was as 5.5 to 1. By comparing the velocity of the wind at this elevation in the direction which the storm advances with the velocity of the storm's advance, Prof. Loomis is enabled to deduce a measure of the force of the upward movement of the centre of a storm.

Storms are divided, by Prof. Loomis, into two classes. Those of the first class traverse the continent northward of the fortieth parallel; many from the remote west reach the great lakes Superior and Huron, and show a decided preference for that region. Some of these have their origin among the Rocky Mountains, and some come from the mountains of Oregon. Those of the second class originate chiefly westward of the mouth of the Mississippi, and move nearly northeast. These comprise only about one-sixth of the whole number, but include some of the violent cyclones which traverse our coast.
