\\th October.— Daylight strong gale S. E. ; at 8 p. m. the same and less sea. 

 Bar. 29.30 and 29.10, rising rapidly; Noon, Lat. 20° 41' N. ; Long, 114° 30' 

 East. After which fine weather gradually returning with Southerly winds. 



The following notice from a Singapore paper does not afford us any 

 assistance in tracing the Cyclone track, but it is always a lesson (if more 

 are needed) to shew the mischief which is done by disregard or ignorance 

 of the laws of our science. I have no sort of doubt that it was a part 

 of the same Cyclone to which the preceding logs relate. 



" The ship Tyrer, Ellis, which left China on the 9th October 1845, with a cargo 

 of Tea, bound for London, arrived here on the 15th November, having experienced 

 a very heavy Typhoon on the passage. We have received the following particu- 

 lars of the voyage. The Tyrer left on the 9th ult. with pleasant, weather. On 

 the 10th at 4 p. m. commenced with small rain and wind increasing, — continued 

 to blow very hard until 10 o'clock next morning when it blew a perfect hurri- 

 cane, and the ship refusing to steer any longer broached to. During eight hours 

 the ship was on her beam-ends, and blew away her jib booms, jib, fore royal- 

 masts, two quarter boats, washed away all the bulwarks, — and a. great quantity 

 of sails, water casks, &c. went overboard : — every thing was cleared to cut away 

 the masts in case the ship went any lower. When the ship at last righted she 

 had three feet and a half of water in her hold. From 10 a. m., on the 11th until 

 8 p. M., the wind was from N. N. E. to N. W. The day after this severe storm 

 four of the crew were seized with fever and ague — the next day 13 more were 

 down, and ultimately for three weeks there were only five persons left in a con- 

 dition to work the ship, viz., the Captain, two mates, the cook and the steward. 

 We think great credit is due to Captain Ellis for the manner in which he brought 

 his ship down under these circumstances. It is supposed that about one-third 

 of the cargo has been damaged." 



Remarks. 



Track H. 



I begin here, as previously explained, with the Cyclone of H M. 

 Steamer Driver, which vessel seems to have had it on an average from 

 N. E. to S. E. and to have been at 5 a.m. when nearest the centre, 

 not far from her position at noon on the 7th, being hove too during 

 most of the interval. With the best allowance I can make for her drift, 

 not having the detailed log to refer to, I should allow for this Cyclone a 

 track to the W. b. N. as I have marked it ; I do not connect the two 

 tracks, as we have no authority for so doing.
