Things Worth Knowing
OERUMB seem destined to take the
place of medicines In the treat
ment of diseases. We have all been
familiar from childhood with the
serum used in vaccination against
smallpox. Of recent years we have
heard much of vaccination against
typhoid fever, and such of us as are
oemDcrs of the army or the National
Guaru have had this anti-typhoid
serum injected into us. Diphtheria
is being cured with an anti-toxin, and
only lately a serum has been used
most successfully in curing car
All the world has been discussing
Dr. Friedmann s serum that he says
will cure tuberculosis, and two conti
nents are anxiously watching the re
sult of the tests made in New York
by him.
Within the last few weeks it has
been announced that a serum that
will cure pneumonia is being per
fected at the Rockefeller Institute for
Medical Research, and that Prof. Beh-1
ring has so improved upon the diph
theria anti-toxin that it is now per
fectly harmless and lasting in its

rxtEP breathing exercises, so bene
facial to persons tn ordinary good
health, are often too tiring for those
to whom they would do most good—
those, for example, who are suffering
from some disease Of the lungs. Dr.
Pescher of Paris, having to treat a
child with pleurisy, desired to give
her pulmonary gymnastics, but found
it impossible to make use of the or
dinary procedure. So he deviaed a
novel scheme of his own, which he
calls the "bottle system."
When one takes a bottle full of
water aad reverses it into a vessel
containing a little water the bottle
does not empty. But if one take ft
rubber tube, insert one end into the
bottle and blow through the other,
he can drive out all the water, the
place of which will be taken by th«
air he expires. Upon this elemen
tary fact of physics Dr. Pescher bases
his system.
The quantity of air that ordinarily
circulates in the lungs of an adult is
about a pint; in those of a child it Is
about two-thirds of a pint. When one
blows a quart of air into a bottle he
is performing an intensive act of
respiration, for he has doubled the
normal quantity of air circulating in
his lungs.
In this case of Dr. Pescher's child
patient he gave her pint bottles to
blow the water out of, making her
repeat the performance twenty times
in the morning and a 9 often at night.

PLATINUM Is among the most pre

now more than twice as expensive as
gold. The metal has been utilized
more extensively during the past few
years than ever before in the Jewelry

and In the scientific and the industrial

After a few days he increased it to

game and was soon emptying half
gallon bottles with one expiration.
The result of these pulmonary gym

Dr. Pescher was so encouraged that
he has made this bottle system s

The use of the metal in dentistry has
been somewhat curtailed in recent
years because of the high price.
Platinum is now finding favor among
artists, who use it to embellish picture
frames, in which it makes an excellent
contrast with gold. It always retains
its color and is not tarnished by sul
phur fumes.
When a high temper and elasticity
are required in platinum it is neces
sary to add iridium. This alloy offers
great resistance to intense heat and
strong acids. An alloy oi 90 per cent,
platinum and 10 per cent iridium is
tsed for writing pens as well as for
points of fountain pens.
In the silver industry platinum is
used for the construction of distillery
covers. These must be made from a
material which will resist various
acids and high temperature. There is
no other metal which possesses so
many advantages in this respect as
platinum. Notwithstanding its great

should be referred to the gas company.
In lighting the oven the torch or
pilot should always be uted and then
turned off. This is simply for lighting,
not for heat. Another precaution
which certain housekeepers have been
known to neglect is never to leave the

If its blood be drawn and filtered to

It will be well to remember that

Lead and zinc when combined with
platinum make it brittle.

Many housekeepers have found a
j one-burner oveu, which sets on the
| top of the range, a decided economy,
i and say that it soon pays for itself in
the gas saved. This also solves the
problem of a warming oven, the ab
sence of which is tbe one objection to
the gas range.
For most families it is worth while
to have sheet iron baking sheets made
to fit the oven, and a slide tray for the

ple enough matter, she will find it quite
worth while.
