Book excerpt: Excerpt from Elements of Chemistry: In Which the Recent Discoveries in the Science Are Included and Its Doctrines Familiarly Explained; Illustrated by Numerous Engravings, Designed for the Use of Schools and Academies It is hardly necessary for the author of the following volume to make any excuses for its publication, since, notwithstanding the multiplicity of books on the same subject, there seems to be none, which arc exactly adapted to the object for which this is principally designed. The Conversations on Chemistry, and the works of Parke and Joyce, besides the interlocutory form in which they are written, are objectionable, in not containing the recent discoveries and improvements in the science; and the volume of Dr. Turner, though free from these objections, is too large for the use of schools and academies. In this volume, it has been the intention of the author, not only to avoid these objections, but, at the same time, to explain the elements and doctrines of the science in sufficient detail, to give a competent knowledge of its several parts, and in such language as can be understood by those who will but read the book attentively and pursue the subject in course. It appears to the writer, that in teaching Chemistry to youth, its elementary parts have not been sufficiently insisted on at the beginning. Of all the sciences, this is the most complete, in respect to its language - the order of its arrangement, the succession of its subjects, and consequently in the facility with which it may be learned. But from these perfections, arises the absolute necessity of becoming well acquainted with its first principles, before the student can derive and retain any useful knowledge from its study. The nomenclature of chemistry, the laws of affinity, and the doctrine of proportions, are far more necessary to a proper knowledge of this science, than is a knowledge of mathematics to the study of Astronomy. The cause of an eclipse or the reason why the complicated motions of the earth should produce a change of seasons, can be fully understood without the use of mathematics. But without a knowledge of affinity, and proportions, the decomposition of a salt, or the formation of a definite compound, are absolutely incomprehensible phenomena; nor can they be explained without a previous acquaintance with the peculiar language of chemistry. It is from a conviction of the importance of first principles in learning this science, that the author has devoted so much attention to the imponderable agents, attraction, affinity, and galvanism, and to the explanation of definite proportions and chemical equivalents.
