1t is stated that Photographic studios
are now connected with most of the
French hospitals, and certain classes
Of patients are photographed on their
entry into the hospitals, and at regular
intervals after. The pictures are pre-
served in albums, and are valuable aids
in the study of disease. An electric
ally operated camera has been de-
vised for this class of work, and it en-
ables the photographer, when des;ra-
BILE, to take series of views in rapid
succession. The photography of mi
croscopic objects is also a valuable
branch OF hospital service, the import
ance of which is rapidly gaining rec
ognition.
During years travel in Bolivia,
Slgnor +. =. Moreno, of Buenos Ayres;
has found many relics of the early in
habitants, has made plans and photo
graphs of tho remains of ancient vii
lagos, and has secured, as he believes,
abundant material for study of the
people who lived in that part of South
America before the Spanish conquest.
1t is usually supposed that dew is
the moisture of the air condensed by
contact with objects which are colder,
and that it does not form until radia-
ton has reduced the temperature Of
the earth and other objects below that
of tie atmosphere. Late observations,
however, indicate that the process is
really the converse OF this, viz: that
the dew is formed by vapor which
rises from the warm soil and is con-
densed by the cooler air. Probably
both theories are correct, neither being
true in all cases.
When heated in forge fire in con,
tact with charcoal, platinum becomes
fusible, Boussingault has supposed
this to be due to a chemical union O,
the metal with the silica of the impure
carbon, but the same phenomenon has
been produced by two German inves-
tigators by heating to wilderness thin
slip of platinum enclosed in lamp
black free from silica.
For producing anasthesia Mons
Paul Bert has found great advantage
in mixing chloroform with air in the
proportions of eight grammes of the
former to 100 .itcrs Of the latter (about
Il fourth of an ounce to four cubic
fect). The administration of the mix
ture is said to be not disaureeable, and
to be unattended with struggling
and sensations Of sutocating. Com
pletc insensibility is produced in six
or eight minutes, and in one difficult
surgical operation it has been con
tinucd for an hour and a quarter
Chloroform has been successfully APP
piled in this way to persons of botl
sexes, all ages, and in all states o
health.
Speaking at Elinburg upon thun
derstorm phenomena, Prof. =. &. Tai
remarked that lightning is 100000
times as brilliant as it appears to us
since the eye requires one-tenth of {
second to receive the full light of the
flash, while the flash itself lasts onl,
about one millionth of second. A.
we see the landscape under the liohr
of spark from the clouds, it is one
thousand times less light than whel
illuminated by the sun, but if the
lightning lasted one tenth of sec
ond-so that We could realize it's full
intensity-it would blind us with the
brilliancy of 100 suns.
In consideration of the effects O
climate in India upon disease, Mr.. 5
\. Hill has reached the conclusion
that crimes of violence in that countr,
are largely results of weather inhu
ence, being proportional in frequeue,
to the tendency to 'prickly heat, thai
excruciating condition OF the skin in
duced by a high temperature com,
bined with moisture" lie believes
that any person who has suffered this
ailment, and knows how it affects his
temper, will readily understand how
the conditions which produce it may
sometimes lead to homicide and othe,
crimes.
