Chemistry.^*

Introductory.

Explanatory examples of common chemical terms and processes, e.g. Chemical Affinity; Difference between Mechanical Mixture and Chemical Combination; Simple and Compound Substances; Synthesis and Analysis.—Solution; Precipitation; Filtration; Decantation; Distillation; Sublimation.—Crystallization.

It is a great comfort to the Teacher, as well as to the uninitiated student, that a free use of the most essential items of chemical phraseology be gained at the outset by appropriate explanations, supported by examples borrowed as far as possible from every-day life.
