In the account given of the Newry Experiment, the boys were equally
ready in applying for their own benefit the lessons they had drawn from
their knowledge of anatomy and physiology. The account says, that "the
most interesting, as well as the most edifying part of the examination,
and which exhibited the great value of this method of teaching the
sciences to the young, was the _application_ of these lessons to the
circumstances of ordinary life. Circumstances were supposed, in which
they or others might be placed, and they were required to apply the
lessons they had drawn for their direction, and for regulating their
conduct in every such case. This they did with great sagacity, and
evident delight, and in a manner which convinced the audience that the
few hours during which they had been employed in making these
acquisitions, instead of being irksome and laborious, as education is
too often considered by the young, were obviously among the happiest and
the shortest they had ever spent in almost any employment,--their play
not excepted. We shall give a specimen of these, and the answers given,
as nearly as can be recollected.

"The case of walking in a frosty day was supposed, and they were asked
what, in that case, ought to be done? The answer was, That we should
take care not to fall. Why? Because the bones are easily broken in
frosty weather.--When heated and feverish in a close room, what should
be done? Let in fresh air; because it is the want of oxygen in the air
we breathe that causes such a feeling, but which the admission of fresh
air supplies.--When troubled with listlessness, and impeded circulation,
what should we do? Take exercise; because the contraction of the muscles
by walking, working, or otherwise, forces the blood to the heart, and
through the lungs, by which health and vigour is promoted.--Where should
we take exercise? In the country, or in the open air; because there the
air is purer than in a house or a town, where fires, smoke, frequent
breathing, and other things, render the atmosphere unwholesome.--Would
breathing rapidly, without exercise, not nourish the blood equally well?
No; because although more air be drawn into the lungs, there would be no
more blood to combine with its oxygen.--What should be done, when
candles in a crowded church burn dim, although they do not ne
