392 Mr Stewart on a Volcanic Eruption in Sumhawa. 
At the island of Ternate, in Lat. 0^ 19' N. and in Long. 127* 
29' E., the explosions were distinctly heard about noon on the 
11th of April ; dust was not perceived to fall there, nor did any 
person notice that that day, or any one of those immediately fol- 
lowing, was at all darker than ordinary. 
In the island of Amboy na, on the 11th or 12th day of April 
in the same year, a violent earthquake was 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 immediately 
after to close. The sea in the neighbourhood of Amboyna was 
violently agitated during that month, rising to high-water mark 
and sinking to low- water mark in the course of ten minutes. 
For several days, at the same time, the sun appeared (according 
to a letter from the late Lieutenant White, of the Bombay ma- 
rine, then at Amboyna) of a green colour, encircled with a haze. 
Fort Victoria, on Amboyna, lies in Lat. 40' S. and in Long. 
1280 14' E. 
The inhabitants of the island of Banda, one of the Moluccas, 
experienced shocks of an earthquake at the time of the eruption 
of Mount Tanbora. 
Art. XXIV. — Some Ohservations on the Solar Eclipse, Sep- 
tember 7. 1820. By Thomas Johnson, Esq. 
OR several days prior to the 7th, I examined the sun wdth a 
reflector, in order to see whether or not any spots were on the 
disc; but none could be seen. The morning of the 7th was clear 
and fine ; there had been a dense fog in the night. At 6 A. M. 
the thermometer in the shade stood at 52®, a little wind S. £. 
by S. At nine the thermometer reached 66® 30', wind S.S. E. 
At 10 thermometer 64®, fresh mnd S. by W., thick fleecy 
clouds, at a low elevation, gliding rapidly before the wind. 
11 A.M. thermometer 65® ; 11^ 49', thermometer 69°. At noon 
very cloudy, therm. 70®, increased at 0^^ 7' P. M. to 70|; O^^ 23' 
69®. At 0^ 51' first observed the sun, but by no means clearly, a 
considerable portion was then eclipsed: large masses of dark clouds, 
rising from the S. very soon obscured the sun again. The next 
time there was an opening, (I did not note the time, but believe 
it was about 1**) and the sun was for about five minutes toler-
