1845.] for the year 1843. 609 



indication of any such phenomena are given, and the point must remain 

 an undecided one. 



The general direction of the shock was from South- West to North- 

 East ; from the relative geographical positions of Pulo Nias and Singa- 

 pore, the direction in the latter island would be from West to East, 

 just the contrary to that specified in the extract above given ; in Penang, 

 on the other hand, the course would be from South to North, as cor- 

 rectly stated by the writer in the " Penang Gazette." 



Indications of atmospheric disturbance accompanied the shock at 

 Singapore and Penang, and most probably at Pulo Nias also, although it 

 is not so stated in the published notices. At Singapore, nearer to the 

 focus of the shock, these disturbances were greater than at Penang, and 

 it is a fact to be noted, that at the former place, very heavy rain imme- 

 diately followed the convulsion. 



4. Earthquake of the 8th January, 1843. — This shock, which was 

 very slight, was experienced at Penang, about midnight of the 8th 

 January. It was not accompanied by any phenomena requiring special 

 record, and was the last of the series which in the early part of 

 the month of January were experienced throughout the Eastern 

 islands. 



5. Earthquake of the Sth February, 1843. — This shock was experi- 

 enced at Ahmedabad in Goojerat, at 2 a.m. on the 8th February. The 

 direction was from N. E. to S. W., and four distinct vibrations of the 

 earth were observed, the entire duration being about eight minutes. 

 Before the shocks were felt, there was a great rumbling noise as if carts 

 or carriages were passing by. 



These shocks were evidently of slight intensity and limited range, 

 there being no notices of their having been experienced elsewhere than 

 in the neighbourhood of Ahmedabad. So far as inference may be made 

 from their direction, they would seem to have emanated from the tract 

 of the Vindayas. 



The early part of the month of February 1843, was remarkable for 

 other indications of volcanic activity. On the 6th, one of the small vol- 

 canic hills on the Arracan coast, near to the station of Kyouk Phyoo, 

 exhibited a sudden eruption ; some particulars of which are given in the 

 following extract from a letter to the address of H. Piddington, Esq., 

 kindly forwarded to me by that gentleman.
