USEFUL AND SCIENTIFIC.

ACCORDING to Professor Bert, in
state of absolute inaction, bodily ana
mental, the temperature of both sides
of the head is equal; but when ny
brain-work is undertaken, if the equal
ity does not continue, the left side al
ways shows the higher temperature.
According to Raymond, in cases OF
paralysis the temperature is higher IN
the parietal region than over the rest OF
the Uranium, where, again, the left side
is hotter than the right by an apprecia-
BILE degree of temperature.
Mr.. CHARLES PECK states that the
puff balls of the United States are USE
full because they are edible. He says:
"None of the species are considered
dangerous or even hurtful. Yet some
are so small that they are not of much
value for food. They should be used as
food in the immature condition only,
while the flesh is yet pure and white.
Puf-balls have as an article of food the
advantage over mushrooms that they
are not often infested by insects or their
Larvae, and there is scarcely any posi-
bility of installing any thing else for
them.''
THERE are numbers of ships on which
yellow fever breaks out whenever they
go into the water warmed to about the
temperature of 70 degrees Fahrenheit.
This will occur year after year, and
season after season. The cause is well
known, has no mystery in it, and can
easily be obviated. Any number of
tons of solid filth from yellow fever
ports will be found between the inner
and outer plankings If these vessels,
and they will always remain unhealthy
until it is removed. No amount of
superficial cleansing, whitewashing,
disinfection, or freezing will subdue this
permanently, but only put it in abey-
ance for short time. It must simply
be emptied out.
DU FAY says: "Chance has thrown in
my way another principle which casts q
new light upon the subject of electrici.
ty. The principle is that there are two
kinds of electricity; the first that Of
glass, rock crystal, precious stones,
hairs CT animals, wool and many other
bodies. The second is that of amber,
copal, gumlac, silk, thread, paper and
many other substances. The charac-
teristics of these two electricities are that
they repel themselves and attract each
other. Thus body of the vitreous
electricity repels all other bodies pos
sessed of the vitreous; and, on the con-
trary. attracts all those of the resinous
electricity. The resinous also repels
the resinous and attracts the vitreous.
1t is probable that this truth will lead
us to the discovery of many other things,
as it explains number CT the pheno-
mena."
A COMMITTEE of the British Medical
Association, appointed with the object,
if possible, of supplying the profession
With one or more new an9sthetics which
shall be free from the dangers of chloro-
form, and more prompt in action than
ether, has just published a report of
great Importance, of which an abstract
appears in the London Monthly Journal
OF Science. They report the results of
experimental tests upon dogs. frogs, and
rabbits, of a large number of organic
compounds, but report unfavorably of
all but two, namely, tso6utyl chloride
and ethidene-dichlortde, with which,
and especially the last named, they OBJ
tanned very satisfactory results. With
the dichloride of ethidene the commit
tee felt so much encouraged from its &C.
ton upon the animals that were expert
mented upon that they employed it in
SIX serious surgical operations upon as
many patients in the Western Infirma-
~ OF Glasgow, and with the most salts

CONTRARY to popular belief, says
writer in Cassell's Magazine, it has been
recently found by an Italian profes sor
that fine vegetable perfumes exercise a
positively beneficial influence on the at
mosphere by converting the oxygen of
the air into that powerful oxidizing and,
therefore, purifying agent ozone. The
essences found by him to produce the
most ozone are precisely those which
usage has selected as the most invigor-
ating, such as cherry, laurel, cloves,
lavender, mint, juniper, lemon, fennel,
and bergamot, several of which are in
gradients in the refreshing eau de Co.
logne. Anise, nutmeg, thyme, narcis-
sus and hyacinth flowers, mignonette,
belictrope and lilies of the valley also
No'cAoP oAoHO LII ldCt oil uOWcTS pos
sessing a perfume appear to do so,
whereas those possessing none do not.
This interesting intelligence will be
gratifying to all lovers of flowers, and
the cultivation of these lovely disinfect-
ants of nature should be promoted in all
marshy or foul places.
In La Progress Medical, M. Galippe
has called attention to the medico-legal
value of the odor of the human hair,
and has given some new facts. He as
serts that from the simple smell of a
lock Of hair he can tell whether the lock
has been cut from the living subject or
whether it has been composed of hair
that has fallen out. Hair-dressers have
acquired this art, which is said never to
fail them. Hair which has fallen out
has dull appearance, attributable to
disease, and is not easily made up; it
has no peculiar smell. The hair of the
Chinese has characteristic odor of
musk which is so persistent that it can !
not be concealed by cosmetics, for it can
not be destroyed by washing with pot
ash. The hair of the Chinese has also
reddish tinge, and is polyhedral in
