average of winds as prevailing along the track and close to the centre of 

 the storm for the whole five days. 



This summary then, is as follows, beginning with the log of the 22nd, 

 23rd, which is at Noon 22nd by Nautical time, and ending at Noon 

 27th. The winds being given by compass are corrected for 1^ point 

 of Westerly variation, to enable the reader better to compare the curve 

 with Figs. I. and II.

Which gives as the resultant wind South 32° W. 6-5 (hours) in 

 120h. or - 7 of the whole time or run, and as the run was in all 137 

 miles, this would give 74-4 miles, calculated in distance. 



* Nautical men will notice that the vessel is always marked as changing her course 

 two points. I suppose she was steered as long as possible with the wind veering a 

 little on the quarter and then the gradual alteration taken as an average, as is often 

 done in cases of squalls of long duration obliging a ship to bear up. At p. 721 it will 

 have been noted that l\ point per hour is the average change.
