Excerpt from Laboratory Studies in Chemistry
Briefly stated, the main features of this laboratory manual are as follows: -
1. It covers thoroughly the various syllabi which teachers preparing students for college have to consider.
2. Each exercise, including the writing of the notes, can be finished within ninety minutes.
3. The apparatus required is simple and inexpensive, and due regard has been given to the prices of the chemicals. Expensive substances are employed at times, but only in very small quantities.
4. The fact has not been overlooked that the teacher of science usually carries as many hours on the roster as the teacher who has no apparatus or materials to arrange. I have tried to simplify the manual labor required of the teacher, without reducing the efficiency of the work.
5. The experienced teacher will at once perceive that the practical details of the experiments have been worked out with unusual care. It has, in fact, taken me many years to get these laboratory studies into the shape in which they are here presented, and I have refrained from publishing them until I had made sure that they were as perfect as the painstaking labor of my students and myself could make them. I shall be very grateful indeed for any suggestions as to further improvements from other teachers.
It is, of course, as impossible as it is undesirable to frame a set of directions which shall be a substitute for the teacher.
