cide in showing that this was a hurricane of very unusual vio- 

 lence. (Track E.) 



On the 10th of February, 1849, the barque 

 Nimrod, from Sydney for China, was in 

 17° 38' S. and 161° 26' E., sailing N.W. 



On the 13th, the centre of a hurricane, 

 beginning at N.E. and ending at S.S.W., 

 passed over the vessel, during which she lost 

 her masts, &c. The progressive motion is 

 towards the south-east. 



On the 15th of February, in 23° 38' S. 

 and 167° 40' E.,about fifty-eight miles S.S.E. 

 of the Isle of Pines, the hurricane struck the 

 brig Scamander, veering from E. to S. At 

 10 P.M. the brig was wrecked on the south 

 reef of New Caledonia, and all hands except 

 two drowned. (Track F.) 



From the 18th to the 23rd of February, 

 1852, a cyclone was raging at New Caledonia 

 and Amatam, the schooner Deborah was 

 wrecked. — {Sydney Morning Herald.) On 

 the 5th and 6th of March, the barque Lady 

 Franklin was seventy miles S.E. of Norfolk 

 Island, The calm passed her at 2 a.m. of 

 the 6th. The wind veered from E.S.E. to 

 W.N.W., indicating progression to the W. 

 of S. 



At Auckland, New Zealand, on the 6th of March, there was 

 a furious storm, for the most part from E.N.E. The brig Mau- 

 kin was wi-ecked, and H.M. surveying schooner parted both her 

 anchors and drove on shore. (Track G.) 



In Hunter's ' New South Wales ' is de- 

 scribed, by Governor King, a furious hurri-

 February, 1789. The wind began at N.E., 

 veering round to E.S.E., and then to S. and 

 moderating. Wind S.W. during the re- 

 mainder of the month. 



The motion is south-eastward, the central 

 area passing to the eastward of the Island. (Track H.) 



On comparing the curvature of the tracks thus determined 

 with that of the cehibrated Rodriguez hurricane (Track K), the 

 nature of the anomaly will be apparent. 



It is remarkable that the track marked E, which may be 

 regarded as a mean of all the tracts determined, coincides with 

 the Australian volcanic series, which, commencing about New
