the combustion: the air-pipe to be kept full by the degree of 
pressure that may be found requisite from bellows kept in mo- 
tion by the steam-engine; the size of the bellows to he pro- 
portioned to the number of lights that are to be fed. The lan- 
tern should be made perfectly air-tight, the crown of which 
should terminate, as represented in the sketch, by a tube im- 
mersed in water contained in the basin c. The air vitiated by 
combustion would run into the tube and be forced through the 
water by the pressure of air from the bellows. On one side of 
the lantern hangs an air-tight glove fastened round a hole suf- 
ficiently large to admit a man’s hand; and on the same side is 
a case of matches and a bottle which may be ignited without 
air escaping from the lantern, or finding its way into the lantern 
from the mine. The aperture for the hand may be further se- 
cured by a door on the outside. d is an enlarged sketch of the 
gas-burner and air-pipe which may be united with the lantern 
by the screw e. 
Should this contrivance be founded on erroneous principles, 
which a very limited knowledge of science makes me doubtful 
of, IT hope that I shall be forgiven this intrusion, and that an 
attempt to be useful will, with Sir Humphry Davy, be sufficient 
apology for any liberty of this nature.

Your most obedient humble servant,

*.* The idea of the “ air-tight glove,’ suggested by Mr. 
Carter, deserves the attention of the mine-owners, as it furnishes 
a mean for relighting the lamp when extinguished, without any 
danger of an explosion.— Note by Sir H. Davy.
