912 Fourteenth Memoir on the Law of Storms in India. [No. 168. 



We have no data for assigning any centre to this storm on the 28th, 

 if indeed it was formed at this time, but we can only conjecture it to 

 have been, if formed, to the North and NE. of her on that day. On the 

 29th, however, we may fairly say that her NNE. and NE. gale was part 

 of a true vortex, and that the centre bore about SEbE. from her. We 

 can only estimate, or suppose, a distance for it, and this a very limited 

 one, for if a vortex of large extent it would interfere with the Storm Circle 

 of the Caledonia. That it was not a part of the Caledonia's storm, I infer 

 from the fact that the distance between the two ships (both their 

 positions being well ascertained) is upwards of two degrees, and their dif- 

 ference of longitude very small ; so that the NE. gale of the Juliana can- 

 not be made part of the Caledonia's circle, without carrying this last to 

 reach the John Wickliffe's track, and include her on the 30th, when she 

 had fine weather and calms. 



On this account then I have marked the Juliana's storm for this day, 

 as a separate one, also of small extent. 



On the 30th we have the Juliana with an Easterly gale mode- 

 rating at noon, while the Morley, to the ENE. of her, has hers just 

 beginning at SSW. and was undoubtedly running on to the WNW., being 

 bound to Madras, so as to overtake the more central parts of the storm 

 which gave her the shift of wind to the Eastward, and the half an inch 

 fall in her barometer. We have unfortunately here again but a meagre 

 memorandum, in which the position of the ship for the 29th and 1st 

 are wanting, when these would have been of the greatest importance 

 to our research. 



Of the Myaram Dyaram's hurricane, all we know is, that she had the 

 wind more Easterly than the Caledonia, and occasionally to the North 

 of East.* We know so little as to date and her position, that we are 

 compelled, merely to suppose that it was on this day she had it most 

 severely, and was in distress ; one account (Captain Faucon) saying it was 

 on the 1st, and another (Captain Twynham) on "the same day as the 

 Caledonia," which would be the 30th, and her position gives the greatest 

 probability to its having been on the 30th. f I have therefore placed the 



* Letter from Captain Twynham. 



f Captain Twynham, and Captain Faucon both mention that the Myaram Dyaram, 

 " a short time" or" a few days" before the gale fell in with a vessel from Moulmein.
