calm centre at 7 p. m. having the shift at 7.30. She was probably at 

 this time to the South of the parallel of 20°, and as the Cyclone was 

 curving a little, we can see that its position and hers closely approxi- 

 mate, which is all we can expect with so many sources of uncertainty. 



The Framjee Cowasjee, it will be noted, is upon the parallel of 20° 

 North, and she was on the advancing (Western) verge of the centre at 

 about 6 p. m. when she had the wind North, and moderating to a calm 

 at 8, which would place her also to the South of 20° and close on the 

 track of the centre, as I have marked it. No. 21, the Charles Kerr, 

 offers some anomaly of wind, or of position rendered erroneous by 

 the effect of the storm wave and storm current, which as she was for 

 a considerable time with the wind at North, and hemmed in between 

 the coast and the advancing Cyclone, where she would perhaps have 

 had moreover some part of the Southerly current from Point Palmiras, 

 it is not unfair to suppose that she was a little farther to the Southward 

 and Eastward than she supposed, which will account then for her 

 having the wind so far to the Westward. This ship was also in great 

 distress, her pumps being choked by the sand ballast ; the wind at 10 

 a. m. is marked W. N. W. and p. m. S. W. b. S. so that it veered 7 

 points in two or three hours ! showing that the ship was close upon 

 the centre, and all hands probably too anxiously engaged in freeing the 

 ship, as they were reduced to baling, to pay much attention to the exact 

 direction of the wind for which I have therefore given a curved arrow. 

 No. 20, the British Sovereign, is also an anomaly, if we suppose the 

 Cyclone to have extended so far, but this it could barely have done, 

 and the log of the Teak shews that there was a strong Southerly 

 monsoon following the Cyclone. 



The Teak, No, 2, also presents a slight anomaly, but she had now 

 been three days without an observation, so that her position is neces- 

 sarily uncertain. 



The wind and position of the Asiatic, No. ] 0, however, are at first 

 sight the most difficult to account for, as her position must be tolerably 

 correct since she had just stood off from the coast on the 11th, and 

 though with the N. E. and Easterly gales and hurricane which she 

 had, she appears to have made little more than a W. S. Westerly drift 

 between the 12th and 13th, yet as regards her Southing she must at 

 least have been at noon on the 13th as far to the South as she is
