JIR. JOHN TURMEAU, and CHARLES Se¬ 
ward’s (ciieapside), ^/or a new lamp^ 
called the Liverpool lamp. 
'^HIS is an iinprovernent on the Ar- 
gand lamp, which has been so long 
in use as to be almost universally known. 
The advantages of the Argand lamp, are 
derivecf from ilie circular shape ol’ the 
wick, by vvhich a current of air rushes 
through the cylinder on which it is placed; 
and, together with that which has access 
to tlie ontside, excites a flame to such a 
degree, that the smoke is entirely cosi- 
fiuined, Tiius both the light and heat 
are prodigiously encreaserh, the combus¬ 
tion being exceedingly augmenterTby the 
^uanlitY of air admitted to the flame; and 
ivhat in co.'Rmon lamps is dissipated in 
grnoke is, in this, converted into a bril¬ 
liant flame. Such are the principles of 
the Aigand lamp; tlie defects in this 
are, tiiat the reservoir for the oil, being 
a distance from the burning body, oc» 
Mag., No* 221, 
casions, in cold weather, a congelation of 
the fluid, so as to prevent its flowimr 
freely, and the brilliancy of the light is 
greatly diminished : another circumstaucG 
vvliicli.lessens its value is, that only the 
best oil can be successfully used m it, 
because, from its construction, the sedi¬ 
ment of impure oil clogs the wick, and 
renders the light dim. In the Liverpool 
lamp, there is mnch simplicity in tlie con¬ 
struction: there are neither fountain, 
valves, nor tubes, by which the a - can 
be impeded in its prog.ess to the wick s 
tlie di-tance between tjje reservoir for 
the . i aed flame is such as to favor the 
ascent ol the oil in the wick, and likewise 
) keep th.e oil in a perfect fluid state, even 
m the severest frost: iusu ad ot one circu¬ 
lar or cylindrical wick, as in liie Ar^and 
lamp, there are three flat wicks placed isE 
the chordsofa circle, with a widespacefor 
the admission of airbetween each; besides 
this, there is a' current of air admitted
