has been exposed by Mons. Krechel in
to the French Academy
Of Sciences. As the solution has the
density of good milk the adulteration is
not detected by the ordinary testing IN
struments.
Prof. julius Wicssncr, German ex-
perimenter, finds that the effect Of rain,
dew and artificial watering upon the leaves
Of plants is to promote transpiration and
accelerate the movement Of the sap, This
process may be injurious at times when
the soil does not contain an abundance
Of moisture.
Pork worms are not quickly destroyed
BY salt. In experiments by Mons. Col
lin the trichinn in the superficial parts
Of hams, ETC., survived in brine for fifteen
days, while in a heavy ham the parasites
were not all killed until the meat had
been immersed in brine for two months
While Prof. Tyndall's doctrine that
cholera germs are bred in the human in
testines may hold good, DR.. VIM. b. Car
penter, the English Psychologist, shows
that such germs may have other breeding
places. He gives three remarkable in
stances in which the outbreak Of cholera,
oraat least Of the almost equally fatal
choleraic diarrhea, was directly traced to
offensive piggerics, to an imperfect drain
in marshy ground, and to compost heap
Of unnamable filth in an unused yard.
An International Society of Electric
isnss has been formed in Paris, its chief
object being to promote the development
Of electrical science and its applications.
Prof. P. Denxa has made series of
magnetic observations extending through
twenty solar and lunar eclipscs. His re-
splts indicate that eclipscs have no in
Auence upon the earth's magnetism.
Tho International Bureau of weights
and Measures, established at Paris as Il
result Of an international conference in
1875, has thus far received the support
Of the following countries Germany
Austria Hungary, Belgium, the Argen,
tine Confederation, Denmark Spain, the
United States Of America, France, Italy,
Peru, Portugal, Russia, Sweden, Nor
NJ, Switzerland, Turkey and Venezuela.
These governments, representing over
35O,O0O,O00 people, have already con
tributed over $500, 900 toward the foun-
dation of this institution. The object
Of the Bureau is to secure an internation
a metric system, and its work consists
chiefly Of accurate comparisons and veri
Nications to reduce the metres and killo
ssrammes used in the different countries
TO common standard. 1t is provided
with suitable building, fitted with com
pairing instruments of wonderful delicac,
and precision. The Bureau is under the
direction of committee Of fourteen mem
em comprising physicists, mathematic
ians and astronomers, all Of different ma
!. tiopalities.
The theory that copper excits pro
tective influence against cholera is con
E1rpsd by tho observation that the diseas
~ never appeared at the famous cope
1nines in Fahlun, Sweden, which are de
Ssribed a the largest and Oldest in IT,
world. 1t is even related that member
Of the royal family once sought Fahlu
q refuge during cholera epidemic
Mons. Bailly has lately denied the pre-
tsctive action Of copper, and has show
that copper-workers in certain localit
had fallen victims to cholera and typhoi
.feyer. To this Mons. Burg replies tina
the substance worked by these men wa
an alloy containing only very minut
proportion Of copper.
Prof. Robert Collect, an eminent MOI
wegian zoologist, states that beavers form
eriy inhabited many parts Of Norway, b.
- now found only in two rivers in tn
south. He estimates that not more tina
100 Of these animals exist in Norway /,
the present time, yet he does not beliey
= that the number is diminishing.
I After much experimenting, a Germa
y. savant, Dr.. Haensel, has succeeded
- securing photographs Of several lightnir
flashes. The pictures include part Of Il
landscape, making it possible to estima
the spot where the lightning struck.

A very successful trial of an electr
