386 Foreign Literature and Science. 
The viceroy designs to plant, near Cairo, a botanic gar- 
den, which will be an adjunct to the school of medicine and 
surgery, which he intends to create, and which he has con- 
fided to the direction of European officers. A vast Pissed 
composed of the most remarkable books, in the differe 
languages of Europe, on all the branches of medical science 
is attached to this establishment. He has ordered, in Lor 
don, an apparatus for gas illumination, for the use of his og 
lace at Cairo, and the place in which itis situated.— Revue 
Encyc. Jan, 1826. 
2. Printinc. M. Senefelder, of Munich, to whom the 
arts are indebted for the invention of Lithography, now so 
extensively practised, with more or less advantage, through- 
out Europe, has just conceived a new kind of stereotype, 
which is accomplished as follows :—A sheet of common 
printing paper is covered with a suitable earthy mixture to the 
thickness of half a line, and which, after being properly 
moistened, acquires, in the course of half an hour, the con~ 
sistency of paste. It is then placed upon the plateau of a 
common printing press, and the form of type, without being 
inked, is pressed upon it. This produces a mould, or en- 
graying of the type. The leaf is then dried upon a stone, 
and melted metal poured upon it, by which a casting is ob- 
tained, in a thin plate, eens the ehpeaciers, similar to 
the original type, in ample relief—Idem. 
3. Soot. Henri Bvesousiot has analysed soot, obtained 
from the middle of a chimney in which nothing but wood was 
net and found it to consist of the following ingredients : 
lmin, identical with that which is produced arti- 
pe by saw-dust and potash
