EXPERIMENTAL PROOFS

OF

THE PROPERTIES OF LIME.

Experiment I.

Lime condenses water rapidly, with an increase of temperature.

THIS may be shown by sprinkling a little water on some freshburnt lime. The above mentioned phenomena will take place,and the lime will fall into powder. The degree of heat produc-ed., if a large piece of lime be slaked, is even sufficient to setfire to a brimstone match, if the latter be introduced into thecrack of it. For similar reasons vessels loaded with lime havebeen set on fire.

Experiment II.

Lime has a strong attraction for carbonic acid.

If we bring a jar filled with carbonic acid gas in contact withlime-water, and agitate the latter, a rapid diminution will ensue,and the lime-water become milky. It may also be shown byletting a current of carbonic acid gas pass into lime-water.
