The observations at tlie land observatories indicate that the depres- 

 sion was to tlie north of the Andamans on the morning of the 12th. 

 The centre had thus moved in a north- north- west direction since noon 

 of the 11th. The barometer had risen considerably at Port Blair and 

 Nancowry, and on the east coast of the Martaban Gulf. Strong winds 

 continued at Nancowry and Port Blair, more especially at the latter 

 station. The sky was cloudy at Nancowry, and was still very dark and 

 gloomy at Port Blair. Moderate rain had fallen during the preceding 

 24 hours at these stations. 



A very considerable fall of the barometer had occurred in South 

 West Burmah, more especially at Diamond Island and at Bassein. 

 The winds were unusually strong at Diamond Island. The observer 

 at that station reported a severe gale at 10 A. M. Very heavy rain was 

 also falling in South Burmah. Diamond Island registered 4*58 inches 

 at 10 A. M., and Bassein, 5'97 inches. On the Arakan coast, the weather 

 at 10 A. M. was fine with passing clouds, and light N. N. E. winds. 



The position of the centre can only be roughly approximated 

 from the land observations. It was evidently to the W. S. W. of 

 Diamond Island and at no great distance. The information extracted 

 from the ships' logs enables us to determine it with approximate 

 accuracy. An examination of the positions of the vessels, as deter- 

 mined by observation and dead reckoning on the 12th and 13th, 

 indicates, that the positions assigned to all the vessels, except the 

 Satara, at noon of the 12th, may be accepted as approximately true. 

 There appears to have been very little current in the western and
