.92 Education of the Blind.—Voyage to Iceland, Se. 
of chafing-dishes filled with lighted pieces of wood. Every 
aperture must then be carefully closed, in order to prevent 
any fresh air from entering. The carbonic acid gas, pro- 
duced from the burning wood, proves fatal to the insects. 
Rats and mice, also, are.so strongly affected by it, that they 
are seen running out of their holes, and dying in all direc- 
tions. The persons employed to manage this process must 
take great care of their own safety, by keeping a current of 
air around them until the burning wood is properly placed. 
Another danger may arise from the premises taking fire ; 
but this also may be avoided by proper caution, particularly 
if they are paved with brick or stone. 
EDUCATION OF THE BLIND. 
Professor Haiiy, of Paris, has introduced into Prassia 
his plan for educating the blind, and an institution for the 
encouragement of this laudable object is in great forward- 
ness at Konigsberg. 
VOYAGE TO ICELAND. 
M. Leopold de Buch, member of the Academy of Sci- 
ences at Berlin, and the friend of baron Humboldt, has set 
out on a voyage to Iceland at his own expense, where he 
intends to pass the winter for the purpose of making phy- 
sical and geognostic inane in that hitherto neglected 
country. 
ANTISEPTIC PROPERTIES OF CHARCOAL. 
The crews of the two Russian ships which lately sailed 
round the world were extremely healthy. During the whole 
three years of their voyage only two men died of the crew of 
the Neva, and the Naveshda did not lose a single man. It 
is already known that their fresh water was preserved in 
charred casks, but it is not so generally known that they 
used the same precaution for preserving their salted provi- 
sions. The beef they earried out with them tasted as plea- 
santly upon their return as it did three hel before, ae 
first salied.
