THE HUMAN BREATH.

It Will Not Move Mountains, but Has the Power to Halse Large Books. The horse-power of the human breath is not great enough to scatter a regiment of soldiers, nor will it uproot trees, as the fable tells us, albeit it contains a surprising amount of leverage, which is evidenced by the loud report which a paper bag filled with the breath will produce when smashed between the hands. The following experiment demonstrates the elementary power of the human breath still more forcibly. Take a large bag of good, heavy paper, lay it on the table and cover the closed end of it with several books—a Webster unabridged and a family bible, for instance—then blow into the bag, filling or inflating it with air.

and you will soon see that it- will overthrow the books—that is, remove a small mountain.
