Présentation de l'éditeur
These laboratory exercises are intended to illustrate and to be supplementary to the work of the class room. It is not intended that this book shall take the place of the personal instruction of the teacher; on the contrary, its object is to facilitate this work of the instructor where the number of students in the class is large. The laboratory work and the lectures or recitations should go hand in hand. Before a subject is taken up in the laboratory it ought to be briefly outlined in the class room, and the object of the experiments that are to be made ought to have been clearly brought into the minds of the students. At the same time they must not be told everything that they are expected to observe; they must be given opportunity to acquire the art of observing accurately and of describing what they see. After all the experiments on a given subject have been made, a full discussion of the results is in place. Then the instructor should see to it that the students have observed everything that was to be seen, that proper conclusions have been drawn from the results of the experiments, and that the connections between these results and the general laws and principles of the science are clearly brought out.
