The rise was nowhere large, and was less than a tenth of an inch at all 

 stations in that part of the Bay. A considerable ('l?") fall had occurred 

 at Akyab, and smaller changes of the same character at Chittagong 

 and Toungoo. Judging from the barometric movements, the centre at 

 10 A. M. was in the immediate neighbourhood of Alcyab. 



The wind observations, however, are anomalous and almost unintelli- 

 gible on the supposition of a well defined cyclonic circulation. The 

 winds at Nancowry were steady from south-west, but were very feeble. 

 At Port Blair, the wind was very unsteady, shifting from W. N. W. at 

 10 A. M. to S. S. E. at 4 p. M. Moderately strong S. W. winds continued 

 at Diamond Island. The winds at 10 A. M. at Akyab were from N. and 

 at Chittagong and Toungoo from N. W. They shifted at 4 p. m. to 

 west at Akyab and Chittagong, and to S. W. at Toungoo. They were, 

 however, very feeble at all these stations. The wind velocity averaged 

 8 miles per hour at Akyab, and only 1 mile per hour at Chittagong, 

 where the air motion was actually less than the average in November, 

 which is 2 miles per hour. The only inference from these observations 

 is, that the cyclonic or vorticose motion had been broken up to a large 

 extent by the action of the hills and the friction of the land, and that it 

 was no longer a well-defined cyclonic circulation. This is also indicated 

 by the character of the rainfall at the land stations. It was more widely 

 distributed than before, and was smaller in amount, the largest quantity 

 registered being 2'44 inches at Akyab. 



The vessels which have contributed logs were all on the southern and 

 western quadrants at some distance from the centre. They give in- 

 formation which is less valuable and conclusive than that of the preced- 

 ing days. The whole of the meteorological observations, when charted, 

 indicate that the centre of the barometric depression at 10 A. m. was to 

 the east of Akyab in Lat. 20° N. and Long. 93 J° E., and that the 

 cyclonic circulation was very irregular and fast breaking up. The 

 Mahratta, from Chittagong, entered Akyab harbour at 8 A. m. She had 

 thick continued rain during the night with northerly winds of force 9. 

 The Scottish Hill, in Lat. 17° N. Long. 92° 25' E., was to the south of the 

 centre at noon. She had winds from west to north-west. During the 

 day, the sky cleared, and the sea went down. At noon, weather was 

 fine, although a heavy bank of clouds was still to be seen to the N. N. W, 

 and N. N. E., but it cleared off during the night. 



The Loanda, in Lat. 17° 34' IST. and Long. 92° 46' E. by account, 

 had westerly winds, and overcast skies with slight rain. 



The Satara found herself at noon in Lat. 16° 45' N. and Long. 94° 

 3' E. She experienced moderate winds of force 7 from S. S. E. early in 

 the morning, and continued to have sharp squalls and heavy rain until
