544* A Twenty-third Memoir on the Law of Storms. [No. 6. 



a. M. with the first vessel, which was "then on shore close to Cow- 

 colly light, and at 6 a. m. moderated and veered to the Northward 

 with the Grappler, which vessel appears to have been at some little 

 distance from the Precursor, but not far enough to account for this 

 discrepancy, which we must therefore attribute to those errors in 

 the estimates of the time usually made when the log is written up from 

 recollection as it always is in these cases I suppose ? unless on board 

 of Men-of-war, or where there is a scientific officer on board who is 

 carefully observing while others are carrying on the ship's duties as 

 in the case of the Megna Surveying Vessel with Mr. B. Pilot Bedford, 

 the Biver Surveyor, whose log and register at Mud Point we shall 

 presently quote. 



To come back to Kedgeree then :

The Precursor log says, it fell calm at,. 4h. 30' 5h. 0' 



The log of the Pilot on board the Precursor 



says, it fell calm at, 5h. 00' 5h. 30' 



Grappler' 's log says, moderating at 6h., and veer- 

 ing about the same time or say 6h. 10, 6h. 00' 6h. 10'

The mean of these for the station of Kedgeree 



will be, .... 5h. 10' 5h. 33 



Or that the centre passed there about 5.20 a. m. of the 23rd Oct. 



"We then find the next certain position near to the centre to be 

 that of the H. C. S. Megna off Mud Point at 7 a. m. when "it 

 moderated for a short time and shifted to North" having previously 

 blown at E. S. E. ; but it seems by Mr. Bedford's table to have veered 

 shortly after to N. N. E. and thus to have been for three or four 

 hours before the shift at E. S. E., and for two hours after it at 

 N. N. E. which we must take therefore, to indicate pretty nearly the 

 track of the main body of the Cyclone. This would give us a track 

 to the N. East for that of the Cyclone from Kedgeree. And as we 

 shall subsequently shew the calm space itself was hereabouts of very 

 small extent, so that we may take this to be not far from the truth.
