On the Reality of the Rise of the Coast of Chile. 237 
of Tuesday, the 19th of November, 1822. It lasted three minutes. 
I was then residing about a mile from the coast at Quintero, situated 
on a promontory, about thirty miles to the north of Valparaiso. It 
was a very clear, still, and moon light night ; the aurora australis had 
been vistble, and some lightning had been seen over the Andes. In 
a few minutes after the first shock, there was another, less severe ; 
and from that time the whole night long successive shocks were felt 
twice in every five minutes, each lasting from half toa minute. On 
the morning of the 20th, a little before two, at four, and a quarter 
before six o’clock, there were three more violent shocks, and the 
earth continued trembling in the intervals: this day was hot and 
sunny, with wind; the night was clear and windy. On the morning 
of the 21st, at half past two, ten minutes before three, a quarter be- 
fore eight, a quarter past nine, and half past ten; and in the after- 
noon, at a quarter past one, and at two, violent shocks were felt : the 
weather of this day was like the preceding. On the morning of the 
22nd, at half past four, half past seven, and a quarter past nine, 
there were violent shocks. A little before ten, three successive loud 
explosions were heard, like the sound of heavy artillery ; the earth 
trembling very much after each explosion. At eleven there was 
another violent shock, and between that and one o’clock there were 
three slight ones; the earth then remained quiet until half past sev- 
en: this day there was a thick fog, with cold drizzling rain. On 
23rd the shocks were less violent and frequent. On the 24th there 
were continual Earthquakes until eleven at night. On the 25th 
there was a severe shock, at a quarter past eight in the morning, and 
others until a little before ten. On the morning of the 26th, at a 
quarter before three, there was a shock, which lasted nearly two min- 
utes: this day we had a violent northerly wind, with rain, which was 
considered very unusual at this season. During my stay in Chile, 
from this time until the 18th of January, 1823, continual Earth- 
quakes, more or less severe, were felt every day. ‘Those on the 
10th and 25th of December, were the most violent after that of the 
19th of November. I have learned that after my departure the Earth- 
quakes continued, that they were very violent last July, and had not 
ceased altogether so late as last September. 
The sensation experienced during the more violent shocks, was 
that of the earth being suddenly heaved in a direction from north to 
south, and then falling down again; a transverse motion also being 
now and then felt. There was on the 19th of November a general
