Pressure, it will be seen from the above, had given way, and the fall 

 was greatest at Saugor Island and Chittagong. This was due, as shewn 

 by the wind directions, to the formation of an area of cyclonic distur- 

 bance and barometric depression near the Head of the Bay. The winds 

 at Saugor Island had shifted to south-east, at False Point to north-east, 

 and at Gopalpore to north-west. From the information extracted from 

 the logs, it will be seen that light north-east winds were established 

 over a considerable portion of the north-west of the Bay. Hence, the 

 cyclonic circulation was just beginning to affect the direction of air mo- 

 tion at Saugor Island and was causing it to back. It was, however, not 

 yet participating directly in the cyclonic indraught. The sky was more 

 or less clouded in all parts of the province of Bengal, the air very damp 

 (especially in Behar, after the floods of the previous week), and winds 

 unusually light and somewhat unsteady. 



The following table gives the average rainfall in the seven divisions 

 of the province of Bengal for the 24 hours preceding 6 p. m. : —
