Excerpt from The Science-History of the Universe, Vol. 4
Technically it is difficult, almost impossible, to draw sharp distinctions between the various subdivisions of natural science. Omitting consideration of mathematics, which constitutes a necessary, and convenient mode of numbering, diagram tization and quantitative interpretation of natural as well as of other phenomena a clear and concise language the fundamental sciences are physics and chemistry. Within the last half century the borderland of these two has become so elastic in its boundaries, that there has developed again an original science so closely involving the characteristics of the two fundamental ones that it is called physical chemistry. With a clear understanding of the foregoing ther should be no misinterpretation of what follows in this Introduction or failure to appreciate what has been set forth within the covers of this book by its author.
Chemistry took its origin out of knowledge of small mysteries. Even today many may reasonably look with wonder at the accomplishments of the chemist, who seems to be a master at massive as well as at diminutive legerdemain. Unfortunately, at times it is assumed that he knows more than he does, and some, as in the charlatan days, pretend to be wiser than they are.
