l\Ir. T. Dobson on the Storm-tracks of 



lu the log of the missionary brig ' John 

 Wilhams/ I find a notice of a hurricane 

 which veered from N. to W. and then to 

 S.W. in Jan. 1845, the vessel being thirty 

 miles E.N.E. of Earatonga. The motion is 

 still to the south-eastward. (Track C.) 



In Wilkes's Narrative of the American 

 Exploring Expedition, vol. v. p. 19, is an 

 account of a violent hui'ricane at Upolu on the 16th of December, 

 1840, in which the wind shifted from N.E. to S.W., and the 

 motion was consequently 

 to the S.E. The storm 

 reached the Island of 

 Tutuilah, S.E. of Upolu, 

 on the next day (iZth), 

 the wind changing from 

 . N.W. to S.W. On the 

 1st of December a ty- 

 phoonhad raged near the Laughlin Islands in 9° S. and 154° E., 

 but I possess no ^count of the changes of wind. (Track D on 

 chart.) 



The Raratonga hurricane, described by Williams in his ' Mis- 

 sionary Enterprize,' which also devastated the Navigators' 

 Islands, was undoubtedly one of the class of which the track 

 has just been determined. At Raratonga the wind veered from 

 eastward towards the west, and was therefore moving towards 

 tlie south. 



Lieut. W^ilkes describes a hurricane at the Feejee Islands 

 which lasted from the 22nd to the 25th of 

 February 1840. It came on from N.E. and 

 veered to N. and then to N.W., gradually 

 hauling to the southward. The motion was 

 therefore to the south-eastward. 



At midnight, on the 28th, the missionary 

 brig 'Camden,' Captain Morgan, was in 31°S. 

 174° 7' E., sailing eastward. During the 

 29th the hurricane passed over her, veering 

 from S.E. to S.W. The centre therefore lay 

 to the eastward of the ship, and was moving 

 towards the south, 



Lieut. Wilkes, at p. 381, vol. ii. of his 

 'Narrative,' has shown that the calm central 

 area of a hurricane passed across the Bay of 

 Islands, New Zealand, on the 1st of March, and that the cyclone 

 was moving in a south-west direction. This is likewise confirmed 

 by Mr. Piddington, Horn Book, p. 61. All the accounts coin-
