distance, the ground opened, and a great quantity of water was immediately 

 thrown out, and in several places the ground entirely sunk. At Bans Burreah, 

 Akul Poor, near the sea, the earth opened in 7 places like wells, throwing up the 

 water 10 cubits high; the great Cutcherry there, with brick walls, is cracked and 

 shivered to pieces. At Hulda Creek, near Sancharam Conguy's house, 12 don 

 of ground is entirely sunk ; and many others shared the same fate. 



At Bar Chara near the sea, 5 or 6 cess of ground immediately sunk, and out 

 of 4 or 5 hundred people, above 200 were lost, with all their cattle ; and the 

 greatest part of the remaining inhabitants who ran into the woods have not yet 

 been heard of. At Lafettee Silcope Chuckla the ground in some places opened 

 and threw up great quantities of salt water, and in others entirely sunk ; the 

 channels of several creeks and little valleys between the hills, were filled up with 

 great quantities of sand ; in some parts the water still continues 20 cubits deep, 

 and in others unfathomable. Silluk creak, and Issamuttee river are both stopped 

 up ; several boats laden with goods then coming down are not now able to get out 

 of them ; the country around there opened greatly in some places, and in others 

 entirely sunk : and a great many tanks filled with sand. Bur Coller hill opened 

 about 40 cubits wide. Cess Lung Joom hill, one of the Mug mountains, is en- 

 tirely sunk. Chunggee hill opened between 20 and 30 cubits. Puddaoah creek, 

 at that time without water, opened and threw up 2 hills of sand ; and all the 

 houses in these parts were broken down. Joom Chater Pedea hill is sunk so low, 

 that its top is now on a level with the plains. Rigerree hill, which was very large, 

 opened 30 cubits wide. Joom Palang hill opened 25 cubits. By the accounts 

 already come in there are 120 *dons of ground lost in different parts of the pro- 

 vince ; but these it is feared will not be -i- part of the whole damages, as fur- 

 ther reports are coming in every hour. 



As they were informed that 2 volcanoes were opened, they were in great hopes 

 these will prove a sufficient vent to discharge all the remaining sulphureous mat- 

 ter in the bowels of these countries, and put a stop to any further earthquakes 

 there ; at least for many years to come.

 It has been asserted by some eminent mathematicians, that the sum of the 

 logarithms of the numbers 1, 2, 3, 4, &c. to z, is equal to -i- log. c + (z-f- -j^) X 

 log. z lessened by the series z- -j^ -j- ^^-q^, + Ig^i^ + &c. if c de- 

 note the circumference of a circle whose radius is unity. And it is true that this 

 expression will apj^roach very nearly to the value of that sum when z is large,
