1849.] Seventeenth Memoir on the Law of Storms. 21 



Kong, as parts of the same Cyclone, the Espiegle being at 260 miles 

 distance from the John (J Gaunt to the N. N. W., and the Sir Robert 

 Sale 240 miles to the S. S. W., and thus far out of the utmost verge 

 we can suppose for the outer storm circles. The fact of these gales 

 occurring at the same time, and the direction of the wind with the 

 Espiegle, being in accordance with the circle, would at first sight have 

 led us to suppose that they really formed part of it, but the Ann's log, 

 which appears from the extract made to have been perfectly well kept, is 

 conclusive on this point. The easterly gale of the Espiegle, though veering 

 from N. E. to S. East or through 8 points of the wind circle, we may con- 

 sider to have been either the first efforts of the N. E. trade or that this 

 and the Sir Robert Sale's cloudy and threatening weather on the 9th 

 were parts of a Cyclone of larger diameter, which was not completely 

 formed, its central part only being, as we have seen, with the John 

 0' Gaunt and Ann in full action, and with the last vessel, of excessive 

 violence, with a very remarkable fall of the Barometer at and near the 

 centre. I should remark also, by the way, that we have as yet no instance 

 of the Cyclones of the China sea extending to 600 miles in diameter, 

 and this is certainly not one. 



I have then laid down the track from the logs of the John o' Gaunt 

 and Ann alone as being one about from the East f North to the W. f 

 S. It may be somewhat more or less of course, the exact position of 

 both vessels being uncertain, but this is probably nearest the truth.* 



Track I. 



Manila Tyfoon of November, 1845. 



I have no further notice of this cyclone than the following, from the 

 Singapore Free Press : — 



" By the Caroline from Manila accounts are received from the Manila papers 

 of a severe gale there. It grew dark on Monday the 2d November,! 1845, with 

 very dark murky weather and a fresh breeze from N. E. changing to N. N. E., 

 East and S. E. at which it rested at 3 in the morning. The force of the tempest 

 was from 10 o'clock on the 3d. The bar. fell 75 centesimals. Almost all the 

 ships in the Bay dragged ; the American ship Camera, which left on the 2d re- 



* In the Chart to the Sailor's Horn Book, this track has a more Southern direc- 

 tion, being to the S. W. b. W. from the N. E. b. E. owing I think to oversight in 

 the dates when laying it down for that chart without any Memoir.
