ever known to have fallen before. In the year 1 763, it had 
fallen to 25 inches 10| lines ; and M. J. A. Deluc remarked at 
the time, that this was lower than it had been known in the me- 
mory of man. On November 22. 1768, it sunk to 25 inches 10| 
lines ; and on January 18. 1784, it likewise fell to 25 inches lOJ 
lines. The remarkable depression of the barometer which took 
place on December 25. 1821, was accompanied with a violent 
storm of thunder, lightning, wind, rain and hail, and seems to 
have been universal over Europe. The following observations 
made in Scotland, will shew that the depression was simulta- 
neous throughout all Scotland, and took place on the same day:

13. Fall of a Meteoric Stone at Juvmas in France. — On the 
15th of June 1821, about 4 P. M. a meteoric stone, weighing 
220 lb. fell at Juvinas, N.W. of Viviers, in the department of 
the Ardeche. It sunk five feet into the ground. Its surface 
was covered with a sort of glaze. Before it fell, it appeared 
like an enormous mass of fire. Its fall was accompanied with a 
continued rolling noise, and four distinct detonations. The 
sky was clear, and the sun shining bright.— See the Journal de 
Physique, tom. xcii. p. 463. 
14. Meteoric Slone in Courland. — Between five and six 
o’clock of the evening of the 12th July 1820, a fire-ball, about 
the size of the full moon, and burning with a reddish flame and 
tint, was seen moving slowly from S. to N. After describing 
an arch of 100°, it became extinguished, and its extinction was 
followed with a noise like three rapid discharges of great guns.
