1849.] Seventeenth Memoir on the Law of Storms. 33 



without any reference to this return of the wind to the W. S. W., and I 

 now explain why I do so. 



We have seen in the log of the 27th that the appearances were threat- 

 ening from N. W. to East, and to N. E. on the 28th, and at noon on this 

 last day the Mischief was only 93 miles S. "W. b. S. of Braco Point,* 

 off which the Stephen Lurman experienced a tyfoon between the night 

 of the 26th and morning of the 29th, "the wind going round against 

 the sun," and the Appolline had severe gales about 70 miles outside^ 

 of the Ladrones on the 27th and 28 th. 



The Amazon again had a severe gale from 25th to 28th, and from 

 these provokingly vague notices (which look as if the ship's position 

 was not known) we may guess that on the 27th she was in Lat. 20° 

 Long. 116° 3(V or thereabouts, but again at what hour of the 27th 

 she was in distress we cannot say. At noon of that day the two vessels, 

 Amazon and Mischief were about 85 miles apart. Hence from all this 

 we may deduce that it is probable, as it is certainly possible, that on the 

 28th the Amazon was nearer to the centre than the Mischief and that 

 the Stephen Lurman" s Cyclone was a different one, which was passing 

 down the coast of China from the E. N. E. and may probably have 

 deflected that of the Mischief and occasioned the "W. S. W. gale with 

 which her Cyclone ended. This is very vague, it is true, but we have no 

 better data, and must wait to see if future experience will allow us to 

 suppose that the track may even have curved more shortly to the N. 

 Westward, which, were we to take the Mischief's log alone, we should 

 infer it did. 



The Don Juan's Cyclone. 



If there be no error in the newspaper notice which I have printed 

 at p. 31, this is a very remarkable instance of a Cyclone in the Formosa 

 Channel travelling to the E. N. E. from the W. S. W. We have unfor- 

 tunately no further notices of it, but I place it on the chart both as a 

 new fact, if it is correctly reported, and because, as will be subsequently 

 seen, I have in track T. the Easurain's Cyclone, a very remarkable but 



* The proper name I suspect. By the English, (see Horsburgh) it is usually 

 termed Breaker Point. 



t If this was a Ship from Singapore she was probably not far from the Meridian 

 of the Grand Ladrone, but she may have been to the eastward and have partaken of 

 the Stephen Lurmari's Cyclone.
