the Brig Tula, belonging to 
Mess. Enderby of London, on 
a sealing voyage discovered 
under the Antarctic Circle a 
large extent of high-land, 
skirted by ice, which runs 
from N. E. to S, W. between 
Lat. 65 and 70 S. and between 
Long. 43 and 57 E. of Green- 
wich, to which he gave the 
name of Enderby land, and 
Cape Ann to a large cape on 
it. He could not come nearer 
than 20 miles of it, being pre- 
vented by a field of iee. Thus 
at last the Austral lands be- 
come gradually known. 
In the same voyage Capt. 
Bi&coe discovered a chain of 
Islands to the S. W. of the S. 
Shetlands, which he called 
Adelaide Islands, they are un- 
der the Antarctic Circle and 
near the west side of the great 
land of Gheritz, discovered in 
1599, which has received so 
many names lately, South 
Greenland, South Spitsberg, 
Palmerland, &c. Capt. Biscoe 
deeming this west shore a dis- 
covery called it Graham land, 
it reaches as far as Lat. 68 
due S. of cape Horn, running 
s. s. w. 
This voyage of discovery 
has been deemed so important, 
altho* unprofitable to the own- 
ers, that they have sent again 
Capt. Biscoe to survey and ex- 
plore these lands, and the ad- 
miralty has sent Capt. Kea to 
help him. The Society of Ge- 
ography of London have also 
given their gold medal for 1832 
to Capt. Biscoe as a reward. 
156. GEOLOGY, 
AND PHYSICAL FEATURES 
Of the Atlantic plains of JYbrtk 
America , by G. 8* M. 
They form great natural 
features of the physical geog- 
raphy and' geology of North 
America, which have hardly 
been properly noticed as yet. 
The. plains along the Atlantic 
ocean, skirting the hilly primi- 
tive region, begin in Mew-Jer- 
sey in Lat 41, and extend 
S. to Florida, thence W. to 
Texas, thence all around the 
gulph of Mexico to Yucatan, 
and even beyond to Yeragua 
and Panama: forming thus a 
level litoral region nearly 4000 
miles long, and from 100 to 
150 miles wide on an average, 
the superficial Area exceeeding 
400,000 square miles! the 
whole of which is level, with 
the exception of a few scatter- 
ed and insulated hills of small 
elevation. 
A volume could be written 
on the geography, geology 
and natural history of this vast 
region: my limits compel me 
to give merely a recapitulation 
of the principal features and 
phenomena of it. 
1. These immense plains 
rise only 50 feet above tide, 
water on average, or from 25 
to 75 feet. 
2. The surface is hardly un- 
dulated, the streams have ex- 
cavated broad and shallow val- 
leys and beds, with wide estu- 
aries at their mouths. 
3. They may be divided into 
several tracts, 1. the Northern 
as far as the Chesapeak bay.
