derickehaab from that of Fiskenass, is a group of islands called 
Fulluartalik, now deserted ; but on the shore are the ruins of winter 
dwellings, which are often overflowed. 
Half a mile to the west of the village of Fiskenass (lat. 63° 4’ N.), 
the Moravians founded, in 1758, the establishment called Lichtenfeld. 
In thirty or forty years they were obliged once, perhaps twice, or 
move the poles upon which they set their large boats, called Umiak, 
or Women’s boats. The old poles still remain as silent witnesses, 
but beneath the water. 
To the north-east of the mother colony, Godthaab (lat. 64° 10’ N.), 
is a point called Vildmansnass by St. Egede, the venerable apostle 
of the Greenlanders. In his time, 1721—1736, it was inhabited by 
several Greenland families, whose winter dwelling remains desolate 
and in ruins, the firth flowing into the house at high tide. Dr. Pin- 
gel says that no aboriginal Greenlander builds his house so near the 
water's edge. 
The points mentioned above the writer of the letter had visited ; 
but he adds, on the authority of a countryman of his own highly de- 
serving of credit, that at Napparsok, 10 Danish miles (45 miles En- 
glish) to the north of Ny-Sukkertop (lat. 65° 20' N.), the ruins of 
ancient Greenland winter houses are to be seen at low water. 
Dr. Pingel is not aware of any instance of subsidence in the more 
northern districts ; but he suspects that the phenomenon reaches at 
least as far as Disco Bay, or nearly to 69° north lat. 
Some notes by Capt. Fitzroy, R.N., read at a Court Martial at 
Portsmouth, Oct. 19th, 1835, on Capt. Seymour and his Officers 
for the loss of His Majesty’s Frigate Challenger, wrecked on the coast 
of Chili, near the port of Conception, and communicated to the Pre- 
sident by Capt. Beaufort, R.N., Hon Mem. G.S., were then read. 
These notes refer to the effects produced by the earthquake of Feb. 
1835, in the currents on the coasts of Chili, from the Island of Mo- 
cha to the parallel of Conception. Capt. Fitzroy also mentions that 
the island of Santa Maria was elevated ten feet. 
A letter dated Valparaiso, 22nd of March 1835, from R. E. Alison, 
Esq., addressed to the President, on the earthquake of Chili of the 
20th of February 1835, was then read. 
The earthquake began at quarter past 11 a.m. by a gentle heaving . 
or undulation of the earth ; but the motion increased in a few seconds 
to so great a degree that no person could stand. It destroyed the 
cities of Conception and Chillan, with the ports of Talcahuano and 
Maule, as well as above twenty smaller towns, and animmense num- 
ber of country houses. It was felt to the southward as far as the In- 
dian territory opposite the island of Chiloe ; to the northward be- 
yond Copiapo ; at Mendoza on the east of the Andes; by the crew of 
a ship 100 miles to the westward of the coast, and at Juan Fernandez 
300 miles from it. 
At the port of Talcahuano the same phenomena occurred which ac- 
companied the destruction of Pencoin 1730 and 1751. Forty minutes 
after the first shock the sea suddenly retired so far that part of the 
bottom of the Boca chica, the smailer or southern entrance of the bay,
