772 Ninth Memoir on the Law of Storms in India. [No. 141. 



At Calcutta, being at the time very unwell, I could not register any 

 observation ; but those of the Surveyor General's Office are given in 

 their place. It will be seen from the documents and charts, that these 

 storms are a remarkable instance either of two separate storms of 

 small extent coming up together, or, which I am inclined to suppose, a 

 large storm dividing itself into two small ones, and travelling up with 

 great rapidity towards the coast. The grounds for these views will 

 be as usual shewn in the summary which follows the documents and 

 comparative table. The storms at sea were followed on the 5th and 

 6th of October, by severe inland storms from Gya to Patna, extend- 

 ing to Benares and other places ; but having scarcely any documents 

 from the stations between Cuttack and Gya, we cannot say with 

 any certainty, that the two sets of storms were connected.
