which oxygen gas is condensed; to this 
vessel is attached a lantern, made ‘perfectly 
air-tight, furnished with a thick glass lens. 
The lantern may be locked , to prevent the 
miners opening it, and the admission of gas 
is regulated by a screw valve. Oxygen gas 
may be obtained at a very little expence ; 
and even if it were greater, the saving of 
human life ought to be considered greatly to

_ Alloyed Iron Plate.—A., manufacture of 
prepared iron has been practised, and the 
substance produced used to a considerable 
degree in Paris. The object has been to

boilers, in the construction of roofs and gut- 
ters, is expected to be very considerable.

acoustic labours are well known, lately exhi- 
bited a newly-invented hearing-trumpet,

and the other to the mouth—an improvement 
which promises great advantage in cases 
which do not admit of cure. It was stated’ 
that the idea orignated with Sir Edward 
Stracey, bart., and its testified utility over, 
other acoustic tubes, in affections of the 
ear, in all the different stages of disease, is 
affirmed by Mr. Curtis.
