was observed on this occasion. Not long after the Earthquake, we had 

 one of those violent squalls which have been so frequent of late as to 

 pass almost without observation ; but we have been assured by some 

 of the oldest residents here, that for many years past there have not 

 been such violent storms of wind and rain. As if the electricity in the 

 earth and atmosphere, or whatever else causes storms and Earthquakes, 

 were exhausted, we have had since Saturday a sudden transition to 

 settled weather, with every appearance of its lasting for some time." 



With the exception of its locality, there is nothing requiring note in 

 this shock. 



15. Earthquake of the 10th August, 1843. — Two notices of this shock 

 has reached me ; one from A. Campbell, Esq. at Darjeeling, the other from 

 E. Ravenshaw, Esq. at Patna. Dr. Campbell writes as follows, under 

 date 11th August, 1843. 



"At 15 minutes to 5 p. m. yesterday, 10th August, by my watch, 

 which was 15 minutes fast by sundial time, we had a shock of Earth- 

 quake here, which lasted 20 seconds. Its course was N. W. by S. E. The 

 motion was horizontal : no damage done to any thing. 



" As you have expressed a wish to be furnished with information 

 regarding Earthquakes, I have the pleasure to inform you, that a slight 

 shock was experienced at Patna on the 10th instant, at about 4£ p. m. 

 A letter from Tirhoot (Muzufferpoor) mentions, that it was also felt 

 there on the same date and about the same hour." 



In a very interesting letter, under date the 9th September 1843, 

 Mr. Ravenshaw communicates the following information : — " A few 

 days after I wrote to you about the Earthquake of the 10th August, 

 my Sheristadar told me he had heard springs of water (Bumbas) 

 had suddenly made their appearance in several villages of the 

 district. I immediately told him to send a man to the spot to 

 bring me some of the water, and all the particulars he could collect 

 regarding the date of their appearance ; their number, site, &c. The 

 man returned with seven bottles of the water, and a note in Per- 

 sian from a person on the spot, stating seven Bumbas had appeared at 

 Dostmahommedpoor, Purgunnah Azemabad, about twenty miles East of 

 Patna. Of these two were large and flowing rapidly, and five small ; about 

 a koss West of the village there were seven or eight more, of which 

 three were constantly flowing, the others smaller and less active. He 

 said that others had been heard of at Moza Tilwur, Purgunnah Bhum-
