This book forms one part of a course of elementary chemistry; the other part is contained in a companionvolume on Practical Chemistry. The two books are intended to be used together, the one being complementary to the other; their object is to teach the elements of chemical science.
A real knowledge of chemistry can be gained only by the intimate blending of a properly graduated course of laboratory-work with the lecture-work and reading of the student.
An attempt is made in this volume to present the principles of chemistry as rising out of and resting upon chemical facts, and chemical facts as furnishing the data from which principles are deduced. The book is intended to be used in conjunction with lectures on elementary chemistry, wherein more details will be given concerning important and typical bodies than are found in this volume. The book does not profess to be a descriptive catalogue of chemical facts regarding the properties of the individual elements and compounds.
The authors entertain views rather different from those which generally prevail regarding the relative importance of the various parts of chemistry; they have endeavoured to make the teaching given in this book sound so far as it goes; they have tried to bind together the facts and principles of the science, and at the same time to avoid speculation.
