employed for burning the lsrd-t2nk gases, bu

to see it in action and tho character OF tho re
suits. This MAS done during tbs past weeh, and
tho results vera enlnently satisfactory. Tae
gases were burnt perfectly, and no ether srnet

from the combustion OF ordinary carbureted by.

mixed With the gaaes is thus condensed, and tue

to the ordinary gas burnt in our Dwellings, and
decidedly superior to that With which the gas

purifying tank the gases arc led into
the cafhonlzer,- which consists OF tank
containing gasoline, or other light hydro-caroon
oils, OF about inches i5 depth.

tank gases aud tho gasol,uo vapors, whereby, ae-
cordlng to the well.k known chemical Law Of
atomic Weights. tho former take up exactly go
BY their combining proportion, aud are thus en-
tirely converted into combustble gases. This ia
equally true eveu il the lard-tank gases have not
first been passed through the purifier, and con-
sequently contain much sulphur in their compo-
sltion; for the sulphur combines rith the hy-
drogen Of the gasoline, forming thereby hydro
sulphuric 8cid, OF sulphureted hydrogen.-a gas
which, though uniguted does not support con-
bustion, yat when Lit burns readily with blue
flame.
Tho carburized gases (whether previously pu-
rifed or not makes no difference in their COM
bust,biity) are then led OF either to be burned
in the boiler furnaces, or, il required for illu-
minatlug purposes, to gas-bo1der nhere the
pressure is equallzed, and they are supplied from
thencs through aer.ice-plpes to the various
burners in Use. In burning them in the furnace
it is nos necessary to lead them with care into
