On the 3rd May, — The Hannah, H. M. S. Fox and the Joseph 

 Manook being close in upon the centre seem to have had the wind 

 veering with tolerable steadiness and not vibrating as before. 



Sarah, 4 p. m., successive heavy squalls from S. to S. W. are marked. 



Atalanta, frequent lulls of two to five minutes followed by furious 

 gusts, direction not given. 



The ships putting to sea from Madras Roads do not seem to have 

 experienced any vibration of the wind worth noting, and many of 

 those mark it as " steady at North, &c." As upon an average we may 

 say that the centre of the Cyclone passed at about 30 or 40 miles 

 from the whole of these ships, it would appear from this and from 

 what we have extracted above, either that this vibration occurred 

 towards the outskirts of the Cyclone and towards the S. W. where it 

 may have been owing to the heavy monsoon, which was evidently fol- 

 lowing up the Cyclone, or that it occurred more at its commencement 

 while it was settling down. The fact, however, whatever may have 

 been the cause, is highly worthy of notice amongst other yet unex- 

 plained ones.
