demonstrate the INCUBATION OF Drain
power in children, he called two classes
Of little girls and two of little boys, the
.children's ages being eleven and twelve
years, and set them to work on easy sums
in arithmetic for successive periods of
ten minutes with fve-minute intervals
OF rest then the results of the work,
the calculations and the errors we're care
fully tabulated and compared. The
total number of calculations made by all
the children increased, roughly speaking,
1000, 5000 and 1900 in the second,
third and fourth periods, respectively.
During the third period of ten minutes
the increase of work done was not so
great as st otherperiods; the number of
mistakes also increased, say 450, 700,
$50 in the different periods, here, again,
during the third period, the quality OF
the work was at its lowest. 1t would
thus appear that children Of the ages
mentioned become fatigued in three
quarters of an hour; that the organic
material is gradually exhausted and
that the power of work gradually dimin-
ishes to certain point during the third
quarter of the hour, returning with re-
newed force in the fourth quarter. This
experiment is regarded as demonstrating
that continuous work for school children
of these ages, even though the tasks are
not difficult, ought not to last longer
than three-quarters of an hour.
PAIN AT THE HEART.--Pains in the
heart region are quite common, and the
general dread of this disease makes many
people imagine that they have heart dis
ease when there is any local affection in
this region. 1t is generally true that a
large percentage of those who think they
are suffering from heart disease have
their pain caused by the pressure of the
stomach when distended with food or
gas. Neuralgia or muscular rheumatism
of the chest wall will give similar pains
in the heart which may readily be thought
to come from heart disease. The obscur-
ity which involves the whole subject of
the hearts nervous system makes it i'm
possible to tell definitely about such pains.
Various drugs which will slow the action
of the heart will sometimes give relief.
But it is necessary first to ascertain posi-
lively if the heart is really affected.
Those who suffer from such pains. can
frequently discover the cause better than
the physician There is no reason why
such pains should give cause for alarm.
Even though neuralgia or rheumatism are
causing pain in that region it is not es-
sentially dangerous The best plan at
such times is to keep in dry place, avoid
draughts of wind, rain or wet weather
and remain in lying posture for hours.
This gives the heart rest and gradually
strengthens It. Hot, dry applications
over the region are always good. Those
suffering from neuralgia and heart disease
should always apply hot fannels over
the region of the heart when the pain is
severe This will prevent the neuralgia
from settling in this organ, the most dan
gerous spot.
THE VALUE OF FISH AS FooD.-Prof
w. o. Atwater has just concluded an
exhaustive study of the chemical COM
position and nutritive values of food fish
and the aquatic invertebrates, which is
presented in the last report issued by the
United States Fish Commissioner. The
thoroughness of the work can be under
stood, when the statement is printed that
analyses have been made of the flesh of
1913 specimens of American fish, of ga of
mollusks, and crustaceans, and 100 of the
invertebrates.
There is ample variety of fish food in
this country, as Prof. Atwater tells us
that we may select from no less than
1000 different species of fish. Regard
ing fish proper, the list commences with
the sturgeon and concludes with the skate,
and fish when dried, smoked, sailed
or canned, and oysters and clans are
presented.
THE following are the deductions as to
the food value of fish: Comparing the
flesh of domestic animals and of fish the
latter contains more water and less fat,
and hence less nutritivs material pound
for pound. In the flesh of the founder
there is 16 per cent. of nutrients, in the
cod 1S, while in the lean beef there is
from 25 to 33 per cent. The fatter fish,
as the herring, mackerel, salmon, shad,
AID white fish, approach nearer to beef
In dry or salt fish the nutrients are in
creased, and sailed Goldfish contains %
per cent, salt mackerel AZ, and desicca-
ted cod as high as so per cent. Oysters
with little of the nutrients, only from 0
to 10, Holsters about 18 per cent. In the
consumption of fresh fish, as bought
in the market, by the pound, the quan-
tity of refuse, bone, skin, is more consid-
cradle by comparison than that of meat,
unless piece of the latter with too
much bone is bought.
1t has taken number of years to
make the public get rid of the idea that
in eating fish it was procuring additional
quantities of PHOSPHORUS. Prof. Atwa-
ter is very emphatic in regard to this.
He says:
There is widespread notion that
fish contains large proportions of
phosphorus, and is on that account
particularly valuable for brain food.
The percentage of phosphorus in the
analyses of fish is not larger than is found
in the flesh of other animals used for
food. But if even the fish
were richer in phosphorus, there is no
proof that it would on that account be
better for brain food The question Of
the nourishment of the brain and the
sources of the intellectual energy are too
indeterminate to allow decisive state
ments and too abstruse for speedy solu-
ton There is no experimental evidence
to warrant the assumption TINT fish Is
more valuable than meats or other food
material for the nourishment of the
brain 49, ,.f...,s.e... ,..,.,,,.,s,,,, = \,
- Prof. Atwater, who is careful stu
dent of food generally, is of the opinion
that in the United States too much food
is eaten containing an excess of fat,
sugar, and starch, and not sufficient
proteine. "This, +" he says, lis natural
result Of our agricultural conditions
