Excerpt from The Scientific Class-Book, Vol. 2: Or, a Familiar Introduction of the Principles of Physical Science, for the Use of Schools and Academies The same reasons which impelled us to undertake the adaptation of the first part of the "Scientific Class Book" to the use of schools and academies in the United States, has equally, or even more forcibly, urged the importance of performing the like task in regard to the present work.

This deficiency cannot be said to arise from a want of interest to create a demand for information in regard to the sciences here sketched. The remarkable rapidity with which the arts, dependent for their success on these divisions of knowledge, have recently advanced, evinces that high national interests are concerned in the diffusion of correct notions respecting their phenomena and laws. The treatise on Chemistry will be found to contain a general discussion of the objects of the science, a concise view of the various simple substances of which it treats, and the chemical laws of combination, together with a brief account of the non-metallic and the metallic elements, and their respective compounds.
