    and are unavoidably insufficient to enable tliem to gain a thorougb knowledge of the science. One great advantage of the mode of treatment is that difficulties of nomen- clature^ notation^ cbemical constitution^ and even those arising from conventionality of language^ are explained as they arise^ instead of being massed under the head of Introductory Chapters/^ Preliminary Considerations/^ or General Remarks_,^^ which are not unfrequently too difficult to be understood by a beginner^ too voluminous to be remembered except by the aid of subsequent lessons^ and are consequently the cause of much trouble and confusion. This plan has also admitted of greater prominence being given to ^^The General Principles of Chemical Philosophy/^ the only section to which the student is asked frequently to return until he finds himself naturally employing those principles in the interpretation of the phenomena obtained by experiment. An elementary knowledge of the subjects of Gravitation^ Heat^ Light^ Sounds Electricity^ and Mag- netism cannot be too strongly recommended to the student of Chemistry. The first portion of this Manual would have been devoted to an exposition of these branches of Physics^ so far as they bear on Chemistry^ did not the many special books on Physics render such a course unnecessary. Che- mical analysis frequently involving determinations of tem- perature^ specific gravity^ and atmospheric pressure^ a few paragraphs on these subjects are made introductory to the sections on quantitative operations. Daiton^s hypothesis of the atomic condition of all matter is adopted in this book, the author believing that^ in the present state of knowledge and education^ philosophic conceptions regarding chemistry can only be taught to medical^ pharmaceutical^ and the great majority of general students in some such objective manner.
