time, total darkness, in consequence of the falling dust, from 

 6 P.M. of the llih of April until 11 A.M. of the 12th. The 

 explosions were very loud at that place, and were heard for se- 

 veral davs. 



At Somabava the darkness was complete from .ibout 6 P.M. 

 on the 1 1th until A P.M. on the 1 2th. The sounds were described 

 to me as being exceedingly loud. They had been heard at 

 Sainabaya, and dust had been observed to fall for several days 

 before the 1 1th, during which time the wind was eastwardly and 

 light; on the afternoon of the 1 1th a very thick haze resembling 

 a cloud was observed coming from the eastv/ard. It proved to 

 be the cloud of dust from Mount Tanbora. The anchorage in 

 Somabaya roads is in lat. 7"^ H' S and in long. 112° 58' E., 

 i. e. about five degrees distant from Tanbora. 



Similar but slighter effects of the eruption were felt at Batavia 

 in lat. 6= 10' S. and in long. 106° 51' E. ; at Java Head, still 

 further off, being in lat. G° 4S' S. and in long. 105° U' E. ; at 

 Minto, on the island of Barca, in lat. and in long. ; and 



at Bencoolen, or Sumatra, in lat. 3° 48' S. and in long. 102^ 

 2,8' E. 



At Macassar, in lat. 5° 10' S. and in long. 119" 38' E. the 

 effects of the eruption were felt nearly at the same time as at 

 Somabaya, but in a degree more violeiYt. 



The explosions from the volcano were so violent there, as ta 

 astonish every one ; they shook the earth, and broke panes of 

 glass in the windows of several houses. The cloud of dust was 

 seen coming from the south. There was no wind. 



With a view to ascertain the quantity of dust falling in a cer- 

 tain time, Mr. Paterson, surgeon of the residency there, put a 

 table into the open air for an hour, between 6 and 7 P.M., at 

 which time the dust was lalliiig in great quantity, and the dark- 

 ness total. The di;nensions of the surface of tlie tal)le were five 

 feet two inches by four feet eight inches; the quantity of dust 

 which fell upon it bv 7 P.M. was 15,064 grains at Beema ; the 

 quantity of dust found lying on the ground after tlie eruption 

 was guessed to be at a medium of three inches and a half in 

 depth: at Somabava the depth of it was something loss. 



At the island of Ternate, in lat. 0' 49' N. and in long. 127" 

 29' E., the explosions were distinctly iieard about noon on the 

 1 1th of April ; dust was not perceived to fall there, nor did any 

 person notice that that day, or any one of those iunnediately 

 following, was at all darker than ordinary. 



On the island of Amljoyna, on the I Ith or 12th day of April 

 in the same year, a vifrlent eartlujuake vvas felt. In the ground 

 of a gentleman near the Government-house, the earth was ob- 

 served to open, to throw out a gush of water, and immediate-Jy
