From the preface: "The introductory course in general quantitative analysis, in Part I, deals with a select list of such analytical processes as may be considered useful for impressing upon the mind of the student the principles of analytical work, as well as the importance of exercising intelligence and care in all work of the laboratory. Bearing in mind the fact that in most college curricula this first course must necessarily be brief, the typical classes of methods for a given determination have been treated together. This, in turn, has involved a preliminary discussion of materials and methods of both gravimetric and volumetric analysis.

Part II, dealing with certain special measurements, has been included in recognition of the fact that the highly important instruments and methods there discussed are too seldom understood by the chemists who use them in industrial work. In our own classes we have found lectures upon the theoretical principles underlying the construction and use of these forms of apparatus to be of very great value. 

In part III is included a treatment of the six classes of materials most often considered in courses in agricultural analysis, and probably of interest to the greatest number of agricultural chemists. The significance of the results of the analyses, in connection with agricultural problems, has been given as much attention as was thought possible, without going outside the proper scope of a book of this character. This, it is believed, will add an interest to the laboratory work and supply a certain motivation, otherwise largely lacking."
