Excerpt from Introductory Chemical Practice: For the Use of Students in Colleges and Normal and High Schools

This work is the result of a preliminary trial made with a class in the chemical laboratory of Cornell University, in the Fall Terra of 1874. A small part of the matter contained in it was printed then in detached sheets for the use of the students. The work will be found on examination to present a mode of chemical practice which has the merit at least of novelty; and the experience of the authors justifies their expectation that it will be found to possess the more important merit of efficiency.

Its purpose and methods are fully explained in § I of the Introduction.

The authors in preparing the Second Edition of this manual, after its constant use in their laboratory for two years, have been guided by their experience especially with respect to the average capacity of the student for chemical work, and the value of an experiment in his hands for the illustration of a principle. A few experiments have been modified or rejected and others lmve been introduced, and another section has been added to the Introduction, which will, it is believed, render the Manual more useful for teachers who find the full course of experimental work already too long for the time at their command.

While the Manual is an introductory work, designed originally for the use of students entering upon an extended course of chemical practice, it may be used with profit, as it has been by the authors, for the instruction of students who have too little time at their disposal for a subsequent course of practice in chemical analysis.
