248 PHILOSOPHY OF STORMS. 



The abote chart exhibits the course of the wind on the 

 5th The reader will perceive that the arrows, if prolonged, 

 will meet in a central space of no great magnitude, where 

 the storms must have been at that time, if it travelled reg- 

 ularly from the time of passing the Raleigh, at 3, A. M., of 

 the 5th, till it passed Macao, a little after midnight, on the 

 morning of the 6th, and at the moment when the barome- 

 ter stood lowest at Macao, the wind was north at Canton, 

 and S. with the Levant, both blowing exactly towards 

 Macao, the point where the barometer stood lowest. 



Again, it is worthy of remark, that the wind had been N. 

 for several days at Canton, and immediately on the setting 

 in of the typhoon, the wind became occasionally N. W., 

 whereas, on the whirlwind theory, it ought to have turned 

 more N. E. The same may be said of the wind with the 

 Levant; on the passage of the typhoon, the wind changed 

 round to S. E. as the storm passed away to the N. W". 

 When the storm passed Canton, the wind changed round to 

 the S. E., and continued blowing exactly towards the centre 

 all the 6th, that is, on the supposition this storm moved in 

 the same direction as the West India storms in this latitude, 

 as it is known they curve rapidly, on reaching this latitude, 

 towards the N. W. and N. As to the Lady Hayes, it is 

 impossible to tell where she was, as her log leaves that un- 

 decided; but if she was near Macao at about 3, P. M., of 

 the 5th, then from that to midnight, an "arrow drawn in her 

 locality would, for that time and for some time afterwards, 

 point inwards towards the same space with the other 

 arrows. 



Mr. Redfield says, in the pamphlet before me, that " he 

 considers the depression of the barometer in these tempests, 

 as due to the rotative action, and the point of greatest de- 

 pression, as indicating the true centre or axis of storm." 



But this cannot be the case, for I have shown, in article 88,
