order.

I might appropriately add under this head that a proper attention to the
subject of education would greatly diminish the number of _fatal
accidents_; that it would save _many lives_, prevent much of _idiocy_
and _insanity_, and a multitude of evils that ordinarily result from
ignorance of the organic laws.

FATAL ACCIDENTS.--He who understands the laws of motion knows that a man
jumping from a carriage at speed is in great danger of falling after his
feet reach the ground, for his body has the same forward velocity as if
he had been running with the speed of the carriage, and unless he
continues to advance his feet as in running to support his advancing
body, he must as certainly be dashed to the ground as a runner whose
feet are suddenly arrested. If, then, there is danger in leaping from a
carriage in motion, how much greater is the hazard in jumping from a
rail-road car under full headway. And yet many do this, jumping off
side-wise, so that it is impossible to advance; and some even jump in
the opposite direction from the motion of the car, which increases the
already imminent hazard. From statistics recently collected, it appears
that the great majority of accidents on the rail-roads of this country
have happened in this way, a want of practical conformity to this one
law of motion being the prevailing cause of fatality along these
thoroughfares. This is but a specimen of the fatal accidents that are
continually occurring in the every-day transactions of life, which might
be prevented as easily as this by the practical application of a single
scientific principle.

LOSS OF LIFE.--In a single hospital at Dublin, during four years, 2944
children out of 7650, about 40 in 100, died within a fortnight after
their birth. Dr. Clark, the attending physician, suspecting a want of
pure air to be the cause, provided for the ventilation of all the
apartments; and by means of pipes six inches in diameter, introduced
into every room a current of fresh, pure air, which is essential to
vitality, and allowed that which was vitiated by respiration to escape.
The consequence was, that during the three succeeding years only 165 out
of 4243 children died within the first two weeks, or less than 4 in 100.
As there was no other known cause of improvement in the health of these
children, it may be justly inferred that, during the four years first
mentioned, 2650 children, nine tenths of the whole number, had perished
for want
