 knowledge as to prehistoric times." — Indepe7ident.

J- TER. By R. T. Glazebrook, F. R. S., Fellow of Trinity

perfect mastery of his subject, as Mr. Glazebrook has. One knows nothing of the 



world in which he lives until he has obtained some insight of the properties of matter 



as explained in this excellent work." — Chicago Herald.
