The New Company an Assured Success
Report Of Assistant Examiner
Fisher, Of the Patent ONCE.
1Nc beautiful exhibit Of the Welsbach III
cundcscent Gaslight Company, at $50 Fif-
tccnth street, Corcoran building, was opened
to the public last evening for the first time.
From : O'Clock until after ] | q constant
stream Of people passed in and out of the
spacious show rooms, and all were enthu
siustic in their praise Of the wonderful, yet
simple burner \ few who came to scoll
remained to pray, and also to add their att
tOgraphs to the already long and rapidly
growing list uf subscribers TO the stock Of
the company. On the books of tue com.
rany appear the names Of such solid men aS
Il. u. Hoffman, Chas. q. Glover, Frank
Riggs, A. NJ IOthrop, Of the firm of Wood
all heavy subscribers, with here and there
the names Of department clerks subscribing
for small lots.
Hon. lIoratio King was one of the many IN
tcrcstud visitors, and before leaving cN-
pressed his determination to give the burners
Il practical test IN his own home Quite u
! large number of ladies were among the Wis
! iiois, aud ono aud all expressed themselves
as highly pleased. The entire absence o.
SCOT and smoke will make the burner ready
| fayOritC with hOusckccpCrs., ,whO see with
! di.may the handsome aud expensive ceilings
Of their houses rapidly blackcning under the
| smoky influences of coal gas with ordinary
burners. Tie test meter, showing the new
| burner producing Il much more brilliant
light With exactly unc.holf the amount Of
gns used in the old-style burner, formed
| another attraction for the housckccper. The
entire exhibit is most attractive and will well
repay any one for half hours visit. The
exhibition is open from 3 to 10 Up. m, and
| orders for burners can be left with the
clerk.
In an article ON "Reccnt improvements in
Gas Lighting" published in the Chicago
DoHy Nurs, Mr. Fisher of tile patent office
wrote as follows:
II was reserved FOR an Austrian, Carl AuCr
von Wclsbach TO make the crownng discov.

| cby heat; it must not he expensive; II must
| lie capable of Use with any kind Of gas: and,
| finally, II must give "a good light with the con
sumption Of small quantity of gas, as com

and fragile, looking like network of lace
will last for hundreds of hours in a gas flame

| mantle at once begins to glow with a white
steady, and brilliant light, whichinore nearly
resembles sunlight than any other artificial
burner the combustion is perfect No uncon

and ceiling and TO injure the furniture, a fact
which will greatly commend the Welsbacl

burner without being sOilcd in the. slightest
degree. The Wclsbach burner also fulfls the
fifth requirement of using a small quantity OF

ordinary gaS burner, and then by substituting
WelSbnch burner with the same presSur,
and quality of gas. The difference in favor NJ
the Welsbach burner is so great that

prove II COnCluShCly.
This burner, like the others described, cal
he used with any kind of gas coal gas, watcl
gas, fuel gas or natural gas, All give excel
lent results. Moreover, it Is very simple il
construction, and can be easily substituted
for the common burner simply by unscrewint
