nor that it always reaches near to the main canopy of stratus 
cloud. It is probably higher in the more central portions of the 
gale than near its borders, in the low latitudes than in the higher; 
and may thin out entirely at the extremes, except in those di- 
rections where it comcides with an ordinary current. Moreover, 
in large portions of its area there may be, and often is, more than 
one storm-wind overlying another and severally pertaining to con- 
tiguous storms. In the present case, we see from the observa- 
tions of Prof. Sneru and Mr. Herrick, at Amlierst, Mass. and 
at Hamden, Me., (115 and 135 6) that the true storm-wind, at 
those places, was super-imposed on another wind; and various 
faets and observations may be adduced to show that brisk winds, 
of great horizontal extent, are often novation; vertically, to a very 
thin sheet or stratum. 
Loca Tornapo 1x tHe Cusa Horricane.—The accounts 
from Matanzas mention a destructive phenomenon of this kind as 
having taken place at Yabu, (in the central part of Cuba, lat. 22°, 
lon. 29° 34/, on the right of the axis line,) during the hurricane: 
It is described: as “‘a tremendous water spout which passed 
through the place, doing much damage,” and confined to a nar- 
row path. “'The effects were the same as if a violent river had 
run through the town, leaving a kind of channel.” This case 
has since | meee, Sppitionad, phroneanaly as having occurred im 
Mexico. « 
The appearance “ee violent ced cearrahican within the body of 
a great storm is not new nor very unfrequent. A remarkably de- 
structive case occurred at Charleston, S. C., on the 10th of Sept. 
1811, during a great storm which visited our coast. It caused 
the es of a great amount of property and about twenty lives. 
Its track was about one hundred yards wide; and it followed 
the course of the local storm-wind, from southeast to northwest; 
transversely to the progression of the great storm. Two very 
violent tornadoes appeared in New Jersey, in a general storm, on 
the 19th of June, 1835, moving in different but nearly parallel 
paths, at an interval of several hours, ‘These pursued the course 
of the higher general current which then overlaid the great 
storm.* Several other tornadoes, together with numerous gusts 
4000 tthe was the New Brunswick sorande deseribed in this ie vol.
