Tables III (a) and IV (a) give the temperature change and varia- 

 tion from the normal for the same provinces and divisions as tables I 

 (a) and II (a), prepared in the same way and with the same purpose, viz., 

 to show the southward movement of the wave of disturbance. To assist 

 the eye I have had the larger changes and the larger variations printed 

 in bolder type. It will be readily seen that the rapid fall of tempera- 

 ture began in Assam and North Bengal on the 29th June, in East Ben- 

 gal on the 30tb, in South-West Bengal and Orissa on July 1st, and in 

 the Circars on the 2nd. There is here clear evidence that a wave of 

 falling temperature proceeded from North-East India in a southerly 

 direction beginning about the 29th June, and reaching the more southern 

 distriots three days later. Akyab and Diamond Island felt the change 

 later and not to the same extent, as might be expected from there being 

 a westerly element in the movement indicated by subsequent tables. 



From Table IV (a) it will be seen that mean defect in Assam was 

 5° - 7 on June 30th, about 5° over the whole of Bengal Proper on July 1st, 

 4 0, 3 in Orissa on the 2nd, 3°1 in the Circars on the 3rd, and 4° 6 at 

 Akyab on the 4th, while at Diamond Island there was a moderate to 

 large excess throughout the period. 



It is impossible to say whether the fall of 1°*5 at Diamond Island 

 on the 5th is connected with the wave of falling temperature so clearly 

 indicated as proceeding from the north-east or with the cyclonic dis- 

 turbance which began over the south of the Bay about that date.
