| course Of the experiment the Thermometer rose 70
20 degrees. and the cattle under cover seemed 10
suffer from being too warm. IL was found tn
a;roexnense 20 comb them regularly, which speed
! ly produced very marked improvement.
I,cyustafions in Steam BOlters.-A pa
tent has been granted in England to T. Ashworth
| If Bristol, for a compound whose object is to pre-
vent ncrustations in new boilers and to loosen
them in old ones. 1t should be introduced in the
boiler twice a week in the proportion Of one gall
lon for each thirty horse power. The compound
is prepared by mixing intimately 30 gallons Of coal
tar, q gallons of linseed water, lbs. Of pulver
lied black lead, and 3 lbs. of CASTLE soap. Lin
seed water is prepared by boiling IA lbs. of seed in
u gallons Of water and removing the seed. The
mixture is of a creamy consistence.
Stereoseopic DaguerreOtype.-Ihis 10 an
English invention, now few months old, when II
not very practical is at least very curious Two
photographs are taken simultaneously from the
same object, in two adjacent cameras, 30 placed as
TO correspond to the slight difference which exists
in the images Of an object seen with the left or right
eve. These two images are placed in a stereoseope,
that is, in a case 50 disposed as to admit the view
of one picture to the right eye, and OF the other
TO the left eye. The two become entirely blended
together and produce this optical illusion, that
instead Of lst picture, YOU see solid objects,
and faces with the appearance Of life, in which
motion alone is wanting.
Cuvier Prize 10 Professor A gassi,. This
prize has this year been given by the French
Academy of Sciences for the first time since its
foundation. 1t has been voted unanimously to
award it to Prof AgGssiz, for his work entitled
'Reckerches sur les PoiSSoas FOsSiieS.' Re-
searches On Fossil Fishes.)
Camphene LampS.-Prof. Hosford has
exhibited before the American Academy Of Arts
and Sciences, at Boston, tin camphsne vessel,
whose explosion at Salem caused the death Of a
female. The stopper was still in its place. He
exhibited the fragments Of glass lamp which had
exploded, seemingly without contact with the
fame. We have seen the following fact which
may serve as an explanation at least of some Of
the cases burning glass camphene lamp was
taken by the handle, which instantly gave way,
leaving hole open at the side Of the lamp. The
person holding it blew it Immediately out, and by
so dong prevented an explosion. On inquiry, it
turned out that a servant girl had broken it in the
morning, and carefully replaced the piece to avoid
being scolded.
MonoclaUc or Uni TOUch.-Such is the
name of a very ingenious but complicated instru-
ment invented by MIR. AckIin. It's object is to en-
able any person to play on the piano, organ or
accordion by making band Of paper pass, with
a velocity regulated by the time of the tune across
the instrument. This paper is pierced with holes
corresponding to the notes, and is prepared by
means of a peculiar machine, by simply playing
the tune once on the piano. The inventor ind-
Gates many other useful applications of this n-
stIument that it may be worked with the foot,
so that good player may play on two pianos at
the same time.
Various StGfSticS.-The telegraph from
New. ork to Albany carries sometimes 200 mes
sages day, exclusive of those for the press.
The Hudson River has been closed this year l02
days, or II days more than the average of the last
o. years. The longest time of suspension OF nav
igation as l36 days, in 1928 the shortest was
II days, in 1906. Liverpool had in 1871 pop
ulation of 100000; in ten years it has increased
to 3S4 600; this is growing as fast as any Am,ri
can city. Lake Erie is only 60 to 20 feet deep;
Lake Ontario, which is 452 feet deep, has its bot
tom 23O feet below the level of the sea Lakes
Huron Michigan and Superior, although their
suiaces are much higher, have their bottoms on
the same level as that of Ontario. Lake Erie is
arge reservoirs of water. v.B.
