IMPORTANT TO GAS Cons sUIERs.-The
equable distribution OF gas from one source
supply TO many points of outlet, extending a
large area involves a greater expense than is
sstent with commercial interests and the conse-
quence s that consumers compelled to submit to
the inconVeniences of over and under supply, i'd
dlvdually to apply the remedy.
The head which forces through the supply mains
the necessary amount OF gas for consumers is called
pressure" and is measured by the number OF
tenths of inches of water which it will support in a
syphon tube. Every service pipe that conveys gas
from the line OF greate main depriyes the remain
ing portion OF certain amount of pressure; the
consequence 49, that when large amounts of gas are
to be passed, the pressure at the of supply
and at the terminus, is very far from equal, that
1t is utterly impossible for gas companies to furnish
supply without sensible difference between the
source and extremity OF use, and the consequent
wasteful consumption by the consumers.
There are two means of remedyng this difficulty.
One is to place in the house of each consumer a
GdShOdeT OF sufficient capacity 20 contain the supply
or night and allow It to De 1illed during the day,
and then shut OFF from the street pressure burn
from the holder.
The other is to place in each house, along with the
meter, an instrument called Regulator, which only
shall furnish the needed amount of required tor
each burner, and with uniform pressure.
The first would prove expensive, OfeRSiUe and
dangerous. The second Is the plan generally
adopted, and of the number OF devices conrlved for
this purpose, nearly all have proved failures owing
TO their use of Mercury, or the Fleeible Diaphragm
The two essential qualities 10 be attained in an
eneient segulator, aIe;-slrst delieacy OF adjust
Second, the ability within the instrument tsef, to
increase the pressure when the greater quantity Of
These qualities, with other peculiar advantages,
are combined IN the Regulator invented by Dr. G..
NJ. Cresson. IL has been used with great in
Philadelphia during the past years always pro-
duclng steady light with a saving of from twenty
to thirty per cent in the amount OF gas consumed.

The FINE ARTs.-Two extensive sales of
pictures by auction have unauestionably given an
impetus to art matters in city. Mr.. Robinson,
the wel-knOwn picture dealer at No. 9l0 Chestnut
rect, has fine collection of paintings, which are
to be sold on Wednesday and Thursday evenings
next. An examination OF the catalogue will show
the value of the works. Specimens of the finest
native and European artists are on view at his es-
tablishment. There are some real gems in The COL
lection, and connosseurs will do well to examine
them during the early part of the coming week
Mr.. Robinson has selected the pictures with great
care and conscientousness, and his long connection
with fne art matters is guarantee that nothing OF
m inferior character will be exposed for sale. As
the plInings are ali arranged for exhibition with
great tase and judgment persons interested in the
arts have an ample opportunity to closely inspect
them.
