centre of the Fyzulbarry's storm and that of the ships in the South- 

 ern Hemisphere were sixteen degrees of Lat. apart on this day, there 

 was still about the equator considerable atmospheric disturbance, with 

 heavy streams of wind from the Westward, agreeing with what we 

 should look for as the general effect of the Southern and Northern 

 halves of the storms in each Hemisphere. The Winifred's Bar. also, 

 and it was evidently most carefully observed, is yet about two tenths 

 below the averages before and after the bad weather which she expe- 

 perienced. At midnight of this day we have the Candahar with a 

 heavy gale at N. W. and the Mary Imrie with a terrific one at N. N. 

 E. and taking the last ship to have made about a South course, we 

 find by projection that on the 30th, at midnight the centre of what 

 I shall now on this evidence call the Candahar's storm was in about 

 Lat. 10° 45' N., Long. 65° 0' East, the centre passing near the Canda- 

 har about noon the following day ; the Mary Imrie scudding to the 

 Southward on its Western side. 



\st December. — We have first the Fyzulbarry, which ship had run 

 with her Southerly gale 150 miles to the N. N. E. from noon 30th to 

 noon of this day with the winds between S. S. W. and South, raising 

 her Bar. as she increased her distance from the centre of the storm 

 from 29.30, at 7 a. m. to 29.80 at 10 p. m. or half an inch in fifteen 

 hours ; and obtaining also moderate weather at midnight. I have before 

 shewn on the 29th and 30th November that this ship's storm must 

 have been a separate one from that of the Candahar, and it will 

 be presently seen that it clearly was so. The loose report of the 

 Niagara informs us of nothing more than that she had a rotatory 

 storm about in Lat. 10° Long. 87° of which we may suppose the 

 strength was about noon on this day, and that she was not far from the 

 centre of it ; drifting or running round the S. Eastern and North 

 Eastern quadrants of it, if indeed the expressions used do not mean 

 that she had a shift of wind ; she would then at all events, if not in the 

 centre, be on the Eastern side of it ; so that taking the Fyzulbarry's and 

 this to be the same storm we find that it may have travelled up to the 

 N. b. Westward about 150 miles, or something less, in this 24 hours, 

 and to this the run of the Fyzulbarry 150 miles to theN. b. E. but 

 carrying always a Southerly wind, lends much probability. However 

 the Niagara's position and times of the wind, &c. are so loosely given
