A tremendous eruption of the Tom- 
nearly every house in the village of Sangii, carrying up the 
roofs and light parts. Near Tomboro its effects were much 
more violent, tearing up by the roots the largest trees, and 
carrying them into the air; together with men, horses, cattle, 
and whatever else came within its influence. This will 
account for the immense number of floating trees seen at 
sea. The whirlwind lasted about an hour. No explosions 
were heard till the whirlwind had ceased.—Raffles’s Java.

The spectacle became still more fearful in the evening by an 
earthquake and a violent hurricane.—Annale de Chimie. 
Iceland, 1821.—On 19th December there was a violent 
eruption of the old volcano of Cape Hekla. The barometer 
fell on the 25th almost simultaneously all over Europe, and 
in some cases the magnetie needle was agitated. This 
voleano had been quiet since 1612: its height is 5666 feet. 
On the 19th December there was a discharge of an enormous 
and lofty column of flame; masses of rock, 50 lbs. weight, 
were thrown five miles from the crater: on the day after the 
principal eruption, grey ashes covered the country. The 
volcano was active for several weeks afterwards. 
On 2lst DecemBer, a violent storm raged from the 
south, and on the 26th and 27th a heavy storm from the 
north-east. ‘The barometer (observed by Dr. Thorsteinson, 
at Naes, near Reikiavig, about 74 miles N.W. of the volcano), 
had been gradually falling since the 18th December, when 
it was 29°16, and reached on 26th December its minimum,
