Most satisfactory rsul;s are oiAiiael
hy DR.. Dcmiu-us Frcire, Of Rio JaneiTo,
fcs his experiments in i.ioeulatlns perscn,
with ycIle,. Fever virus in an a.tcEuatec
form. Up to recer: date he had arriiec.
his system Of iaoeul4ii.iB TO $50 persons,
among whom only six deaths occurred
during Sllitsaiuca; quite severe yellow
fever eI ;;.s:..:> The mortality among
persons who had not been treated With
protective incubation vas, according 70
his account, about fifteen iinils as great
To give Us better know!cdG re Of the
phenomena Of atmospheric electricity, Mr.
John Trowtrid-c recommends that the
government, in connection with the sig
nal service, establish number Of electric
a stations throushou, the south and west,
where thunder storms and tornadccs are
30 frequent In certain regions the ten
dency Of thunder storms bling 10 follow
definite paths, daily thunderstorm MAPS
might be issued, showing the probable
path Of approaching electrical disturb
anoes.
In communication to the PhysioIog
ical Society of Berlin, Dr.. Faik stated,
a result Of his researches on drowning,
that when rabbits are suddenly plunged
! into water haying temperature Of 40 or
- degrees Fahrenheit, cramps Of the ex-
piratory muscles occurs, and respiration
ceases. The methods Of restoring the
apparently dead have no relation to the
effect Of cutanecus stimulation upon res
piration, cold water dashed upon the
chest acts upon the heart alone; on the
pape of the neck il acts upon the lower
brain.
The Oldest reference thus far discovered
70 phenomena resembling the sunsets of
1888 appears to be an account of similar
appearances found by German meteoro-
logist in Flemish work Of 1870.
Prominent American scientists are urg
ing the formation Of an international
scientific association, which shall meet at
intersxis to discuss the worlds pr -. ...a.
Tests with calipers Of the circularity
Of fine turned work can be made with
much gcater delieacy By feeling than by
seeing. Late experiments to determine
the reach Of the sense Of touch for meas
uremtnts make it appear that mechanics
With educated sense can detect variation
Of one twenty -,housandth Of an inch,
while there are men Of exceptionally SEN
sitivc touch TO whom differences measur-
ing less than one thirty thousandth Of an
inch are apparent. The fact Of the min
utcness Of the variations detected has
bcen demonstrated by means Of readings
N scaled rule through microscope.
General usefulness in mechanical work
does not demand = closer approach to
accuracy than one ten .thousandth Of an
inch; the more exactive measurements Of
one 6sty.thousandth Of an inch being use
fal nainly As standards.
D u note to the French Academy of
Sciences, Mons. Cailletet has communi-
Gated plan for producing liquid oxygen
which y 40 simple that it is expected thar
n product may socn become an article
= commerce, IS Ique6ed carbonic acid
now is in Germany. He states that when
the gas known IA formene is slightly cor
denscd and cooled in boiling ethylene un-
der atmospheric pressure, ii is resolved
into an extremely volatile colorless fluid,
and this Auid, in returning to gaseous
statc, yields degree of cold sufficient to
immediately lquefy oxygen.
From the character Of the enormous
icebcrgs Of the southern hemisphere
some Of which have been described as be-
ing hundredths Of feet high and miles in
xtent-Mr. r. A. Proctor concludes
thai no Antartic continent can exist, as
- most favorable place for the develop
ment Of such icebcrgs would be sea
do1eed with islands.
