Additional Objections to Redfield’s Theory of Storms. 133

71. It has been assumed, that a storm wading to the left and 
travelling northeasterly, must, at stations passing nearly under 
the centre, first blow as a southeaster‘and afterwards gradually 
change to a northwester. Meanwhile on the southeastern or left 
limb it will blow only from the southwest, and on the north- 
western or right limb it will blow only from the northwest. Con- 
sistently, when the storm travels from southeast to northwest, as 
hurricanes are represented to travel in proceeding from the sphere 
of their origin in the West Indies to the coast of North America, 
it will at stations within a certain distance of a line described by 
the centre; blow from the northeast first. On the southwestern 
limb it will blow first as a northwester ; on the northeastern limb 
as a southeaster. Moreover, that on the last mentioned limb the 
greatest violence will occur, since the general motion of the whirl- 
wind will there coédperate with that of the whirl: Yet in the 
following paragraph Mr. Redfield informs us, (this Journal, Vol. 
xXv, p. 128,) that “In the West Indies, hurricanes begin to blow 
Jrom a northern quarter of the horizon, and then changing to 
west and round to a southern quarter and then their fury is over.” 
72. This account of the direction of the wind in West India 
hurricanes agrees with that quoted by Espy from Edwards’s His- 
tory of Jamaica, Vol: 3d: “ All hurricanes begin from the north, 
veer back to west-northwest, west, and south-southwest, — —_— 
got to southeast, the foul weather breaks up.” 
73. It must be evident, as stated among my “ objections,” that 
when a whirl is first originated, whether it describe a helix, as 
would result from its proyressive circular motion, or a circle, as 
represented by Mr. Redfield in his charts,* it must at thirty two 
stations equidistant from each other and the centre of gyration, 
blow from as many points of the compass. However, when once 
under way, it being granted that the whirling is altvays from right 
to-left, evidently at any station near the line described by the 
centre, it will begin to blow at right angles to that line or from 
the northeast. As the centre advances this wind would gradually 
subside, ‘and, after the’centre should have gone by, it would be- — 
. gin to blow —_— the southwest with increasing force till the se-
