Chemical and Philosophical Apparatus.

The Lectures on Chemistry and Natural Philosophy are illustrated by modern apparatus. To this important additions have recently been made, chiefly donations from George Hazeltine Esq., of London, and Messrs. B. O. & H. W. Chamberlain, of Boston, Massachusetts; among them a Rumkorff's Induction Coil, one of the largest ever imported; a full set of the famous Geissler's Tubes, and a powerful Grove's Battery, together with apparatus useful in the assay of ores.
