those having from 5000 to $4,000 and
those of less than 5000. The patients arc
also divided In three Glasses: The Arst in
cludinR capitalists, proprietors, msnufac-
turers, etc.; the second, members Of the
liberal professions, and the third, the rest
of the population. The fees are of three
grades: Five rublss for the patients of the
first class, three rubles for those of the
second and thirty kopeks for people Of the
third class.
An investigation by Dr.. Richter, of Ham,
burg, Germany. shows that most of the
fres that occur in laundries where benzine
is used to wash clothes are due to electric
sparks caused by friction of the benslne
and the clothing ss the latter Is withdrawn
from the bath. In Hamburg alone fifteen
out of twenty-one fires were due to this
cause. Experiments showed that woolen
materials became positively electrified and
the benzine negatively, and that the differ
ence of electrical tension causes . discharge
strong enough to give . painful shock, pro-
dueing sparks two inches long in some in
stances and lighting up the room in which
the experiments were made. It IL sug-
gested that such fires may be prevented
by charging the sir in the room with
steam.
The first steamer to cross the Atlantic
burning only liquid fuel arrived at the
port of Philadelphia last week from Eng
land. The fuel used was in the form of
petroleum residuum, product of oil of lit
tie value and no known use uuless the ex.
pertinent of using 1t as fuel should prove
successful. The most important advant-
age discovered on the run was that perfect
combustion was possible, an end never OBJ
tanned when coal IL used in the fire room.
The process consists in forcing the fuel
through the center of q steam jet which
passes directly under the shell of the boil
ers, which are protected from the flames
by . superstruoture of brick. The heat is
so intense that the bricks are changed to a
white color, aud the heat is then passed
evenly over all parts of the boiler shslls.
Tho consumption was about twenty tons
of fuel every twenty four hours. while in
the same time thirty tons of bituminous
GOAL are consumed. On this run the re-
siduum was from Rus. Ian oil, but on the
outward trip Pennsylvania oil fuel will be
used.
1t Is probable that the question of the
electrical treatment of sewage will be occu-
pying good deal of public attention be-
fore long. The success of the experiments
made at HavIe, under the super vision of
the inventor, N. Hsrmits, has created
lively interest in Paris, where the expspdi-
ture of 1T, ,000, 900 francs for new sewers
is now under consideration. II. Maynard
Of the Figaro has set up an electrolizer in
his Offices, with which q series of expert
ments will be made in the presence of min
listers, senators, deputies, aud other public
rersonases. N. Humbert, president of the
Paris Municipal Council, already has de-
voted much time to Q consideration of the
process, which, If 1t can do all that is
/ claimed for 1t, threatens to revolutionize
all exciting ideas on the subject of drainage
and to render sewers practically super
fuous. If the foulsst of liquids can be
| rendered odorless and innocuous by q
swift and inexpensive method, one of the
most troublesome of municipal aud ssni-
tsry problems will have been solved.
