I left the hole in the cork open, because if it were not open the pressure of the cork would crowd the air below, and there would be too much in the tube; and then, too, handling the tube warmed it, and the volume of air changes with heat.
Page vi - ... guarantee happiness, neither can a superfluity of learning insure wisdom. When the body from overfeeding grows plethoric its vital energies subside and its life is endangered. The intellect may be mischievously crammed with science. How much we know is not the best question, but how we got what we know, and what we can do with it; and, above all, what it has made of us.

Page 131 - Salt is a compound formed by putting a metal in the place of the hydrogen of an add; that is, an acid differs from a salt simply in having a metal where the acid has hydrogen. Every acid has a salt corresponding to it. For example, as stated above, nitric acid consists of nitrogen and oxygen and hydrogen. Now if we put the metal potassium in the place of hydrogen...
