The quantity of rain that fell was estimated, from very good 
data, at j^^teen inches^ — a quantity nearly equal to what falls in 
many places during a whole year. In some places within the 
limits of the storm, eighteen Inches is supposed to have fallen; 
and Mr Dwight calculates, that, in the month of July, the quan- 
tity of rain that fell amounted to twenty-four inches. The de- 
vastations committed by this storm were tremendous ; but as 
they are only of local interest, we must refer the reader for an 
account of them to the American Journal of Science ^ vol. iv* 
p. 124,-142. 
11. Salt Storm In North America of the Sd September 1821. 
—The dreadful gale which blew at Newhaven from the S.E. gra- 
dually increased from noon till dark, when it raged with tremen- 
dous violence, and continued till near midnight. “ It terminated 
very abruptly, and passed in a very short time from a hurricane 
to a serene and star-light night. Near midnight, a loud report 
was heard by many, and it was observed that the wind ceased 
immediately after.’’ Next morning, the windows were found co- 
vered with salt ; the trees exhibited a blasted foliage ; in a few 
hours, the leaves began to shrink and dry on the windward side, 
and after some days the dry leaves fell, as they ordinarily do in the 
latter end of November. In October, the leaves re-appeared on 
the windward side of the trees, new blossoms were put forth, and 
the water-melon and the cucumber produced new fruit. In 
some instances, the mature fruit was found on the same tree 
with the new blossoms. On the morning after the tempest, the 
leaves were perceptibly saline to the taste at Hebron, 30 miles 
from the sea ; and it is stated, that the same effect was observed 
at Northampton, more than 60 miles inland. — See American

12. Remarhable Fall of the Barometer on December 1821, 
at Geneva^ and In Scotland.^\u the Blbllotheque Unlverselle 
for December 1821, Professor Pictet has given ^a very inte- 
resting account of a most unusual fall of the barometer, which 
took place at half-past one o’clock of the morning of the 25th 
December 1821. The mean height of the barometer at Geneva 
is 26 inches 11 lines French measure ; but on the morning of the 
25th 5 it fell so low as 25 inches 8 lines, which is low^er than it was
