1088 A Seventh Memoir on the Law of Storms in India. [No. 131. 



8 a. m. in the morning, when it was Easterly. If we say even ESE. 

 and that it changed by the South, as it must have done, this was 

 a veering of 10 points in 6 or 8 hours at most; and at Jungypore it 

 was not much less, being, say, from S. E. at 6 a. m., to S. S. E. at 1 

 p. m., or 10 points in 7 hours. It is true that, as shewn by the arrows, 

 the N. N. E. gale of the 4th at Jungypore might be allowed for as 

 an anomaly arising out of the double effect of the Calcutta and 

 Soorajgunge vortices, with perhaps other local causes with which 

 we are unacquainted ; but then we find that this rapid veering was 

 taking place just at the time that the same took place at Bhaugul- 

 pore, which is 100 miles to the N. W. of Jungypore, and as before 

 stated, separated from it by the Curruckpore hills. There must then 

 have necessarily been two vortices, and I have so marked them. 



We have only for the 6th, the different gales abating in the, quarters 

 they should do if they arose from the passage of a circular storm, and 

 farther to the South and South Westward, calms or light monsoon 

 weather, which does not call for any remark, and we may consider that 

 on this day, all direct traces of the storms as circular ones cease. The 

 secondary effect of this great atmospheric disturbance over most of the 

 Bengal provinces were, it will be seen, felt as far as Almora; and the 

 Barometer was probably more or less affected all over India, though 

 unfortunately we have only good observations at Calcutta, Madras, 

 Bombay, Poona, Lucknow, Purulia and Dadoopore, and none for the 

 N. E. angle (Assam.) For the Eastern frontier, from Cachar to 

 Tenasserim, where observations would have been very interesting, we 

 have only those of Chittagong and Akyab. 



III. — The rate of Travelling. 



That already laid down from the Sand Heads to Calcutta of 5.3 per 

 hour between the 2nd and 3rd is, I think, the only one for which we 

 have any fair grounds of inference ; for we cannot afterwards take 

 upon ourselves to say, what influence each vortex might have had 

 upon the other. 



IV. — Other Phenomena. 



The reports from Gya, and from Amooah in Tirhoot, that is to 

 the East and N. E. of the limits of the storm, should not be passed
