Miscellanies. 193 



At most of the Islands, during the late hurricane, the winds in the 

 earlier part of the storm were from a Northern quarter, and in its later 

 periods from a Southern quarter of the horizon ; from which it re- 

 sults that the gyratory action was from right to left, as in the storms 

 which pass to the northward of the great islands and dlong our At- 

 lantic coast. The distance passed over by the storm in its passage 

 from Barbadoes to N. Orleans, is equal to twenty-three hundred 

 statute miles. The time of passage being six days, gives an aver- 

 age rate of about sixteen miles an hour, which accords with the rate 

 of progress which I had previously ascribed to the storms of that 

 region. 



This hurricane appeared in a more Southern latitude than those 

 which are described in my article before mentioned, but pursued the 

 same general direction as that which occurred at the same season in 

 1830, passing over or to the Southward of the great Islands, and 

 across the gulph of Mexico, with a course curving Northwardly as it 

 approached the American coast. — Hence it follows that its atmos- 

 phere must have subsequently passed over a considerable portion, if 

 not the whole of the Atlantic States, according to the prevailing ten- 

 dency of the general atmospheric current in this part of the globe. 

 In its progress from Barbadoes to New Orleans the storm was con- 

 stantly enlarging in its dimensions and sphere of action, which is 

 shown by its increasing duration as it proceeded Westward, as well 

 as by other evidence. 



It is perhaps worthy of notice that the peculiar aspect of our at- 

 mosphere, together with the unusual color and appearance of the 

 sun, which excited so much attention a few weeks ago, was exhibit- 

 ed a few days after the occurrence of the hurricane at Barbadoes, 

 and at Mobile and New Orleans was the immediate precursor of 

 the storm. W. C. Redfield.
