METEOROLOGY. 
16. Meteoric Stone. — A meteoric stone, weighing 16 pounds 
7 ounces, fell from the air at Nanjemoy, Maryland, 10th Fe- 
bruary 1825. It was taken from the ground about half an hour 
after its fall, was sensibly warm, and had a sulphureous smell. 
It had a hard vitreous surface ; its interior was earthy, and of a 
light slate-colour ; and contained numerous hard, brown glo- 
bules of various sizes, together with small portions of iron-py- 
rites. 
17. Falling Stars.- — Dr Brandes of Breslau, and several other 
meteorologists, have for some time past been actively employed 
in making corresponding observations on falling stars. Although 
these remarkable meteors, apparently situate beyond the atmo- 
sphere of the Earth, at first sight appear to move in every pos- 
sible direction, yet, according to the observations of Dr Brandes 
and his friends, it would seem that the most frequent direction 
is the opposite of that of the Earth in its orbit. 
HYDROGRAPHY. 
18. Remarkable Appearance in a Lake.— On the 19th July 
1824, after a storm, the waters of a lake in the district of Lucda 
became as if soap had been dissolved in them, or lime slacked 
in them. They continued in this state the whole of the 20th of 
July ; but, on the 21st, an incredible number of fishes, of va- 
rious sizes, appeared on the surface, which were buried, in order 
to prevent the occurrence of any contagious disease. — Ann. de

MINERALOGY. 
19. Discovery of Iodine in combination with Silver . — ■ 
Iodine was first discovered in marine plants, afterwards in mi- 
neral waters, and even in the waters of the ocean. It occurs 
also, in the various marine molluscous animals, as the Doris, Ve- 
nus, Ostrea,&c., and even in Sponges and Gorgonia. Very lately, 
this curious substance has been detected by Vauquelin in com- 
bination with silver, in some specimens brought from America. 
20. Platina found in Russia. — This mineral has been disco- 
vered in the Uralian Mountains, and, like the platina of Choco 
in South America, associated with fragments of greenstone.
