50 Eleventh Memoir on the Law of Storms in India. QNo. 157 . 



PART I. 



Summary. 

 Southern Hemisphere. 



I have divided this summary into two parts to separate the storms 

 of the Northern and that of the Southern Hemispheres from each 

 other. If we review the tables, and this will be usually found the 

 best means of forming an approximate judgment, at a glance we 

 shall find, that, 



On the 24tk of November — There is fine weather in the Northern 

 Hemisphere with the Winifred in 15|° N. and we have no other 

 Logs for that day in Northern Lat. nearer to the equator. In the 

 Southern Hemisphere in Lat 4° 47', S. a gale had so far begun with 

 the John Fleming as to reduce her to close reefs, but her Bar. had 

 not fallen below 29.72. : yet the thick weather, rain and heavy sea 

 might be thought sufficient indication, that she was on the verge, 

 at least, of the commencing storm, the centre of which must then have 

 borne about S. S. E. to S. b. E. of her ; as in the Southern Hemis- 

 phere we assume, — and this memoir will amply prove it, — that the re- 

 volution of the rotatory storms is from the South (on the left hand) 

 to the West, North and East. 



But we shall observe at the same time, that at Noon on the same 

 day the Flowers of Ugie was, by her Log worked back from Noon of 

 the 25th* within 12 or 15 miks of the John Fleming and yet she had 

 but light airs, calms, and breezes from the South and S. S. W. from 

 noon till midnight, when the weather began to be squally, increasing 

 to a strong gale at Noon of 25th, though even then her Bar. was 

 at 29.80. 



We have then the Elizabeth Ainslie in 5° 10' S. and Long. 84° 25' 

 E. or within 3 miles of the Ugie (though their logs do not mention being 

 in sight of each other) and there are thus possibly errors in the positions 



* The extract sent me begins on the 25th. Nautical time and though the Log 

 is perfectly well and even carefully kept, it has the fault of adopting the 

 Coaster form of marking the run per Log every two hours only ; which thus always 

 renders it in some degree obscure for purposes of after reference and exact calcula- 

 tion.
