most extraordinary, and providential current in favour to the N. E. 

 Barometer in the height of the tyfoon 28.75." Ther. 82 J . Lat. observ- 

 ed 18° 21' N., longitude by chronometer 112 3 43' E. 



If we take this storm to have begun about North, and to have 

 ended at S. E. with the drift as made good by the observations, it 

 will upon projection give a track about from N. 74° E. to S. 74° W. 

 for the centre, which may probably have passed within about 40 or 50 

 miles of the ships. The singular anomaly of a N. E. current is 

 very remarkable. 



TRACK No. XL 



H. C. S. Macqueen's Tyfoon of Hth and \5th September, 1822. 



Document from the India House. 



Log reduced to civil time. 



The H. C. S. Macqueen bound to China was on the 12th Septem- 

 ber, in latitude 17° 35', longitude not given, and on the Hth Septem- 

 ber at noon in latitude 20° 25' N., longitude 114° 50' E. Squally, thick 

 cloudy weather, and second reefs in the topsails. Wind at 1 1 a. m. N. 

 W. but variable, p. m. swell from the North. 3 p. m. increasing fast from 

 N. W. and N. W. b W. and preparing for bad weather. At 6, increas- 

 ing to a tyfoon, and storm stay-sails blown away. Midnight a tyfoon 

 about South. 



15^ September. — Moderating towards day-light, when the ship 

 bore up with the wind at S. E., latitude at noon 20° 53' N. In ad- 

 dition to the log, there is also a memorandum by Captain Bax, who 

 was second officer on board the Macqueen, but he states the wind to 

 have veered by the East to S. E. which would make the centre 

 pass to the South of the vessel, whereas by the log it evidently pass- 

 ed to the Northward of her position, and I have preferred the log as a 

 written record, the memorandum of Capt. Bax being apparently from 

 memory. There is no wind marked in the log except N. W. at 

 1 p. m., but from the coming up and falling off of the ship, it is clear 

 that the wind veered as I have stated. I have, however, in conse- 

 quence of this discrepancy, marked the track as doubtful, meaning
