Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Laboratory Outline of Elementary Chemistry In preparing this Outline, several things have been kept in view. For example: The selection, the order, and the form of statement have been arranged so as to harmonize with, and suitably to illustrate the subject matter of the Author's "Text-Book of Elementary Chemistry." The apparatus has been made as simple and small in amount as possible. The list of chemicals has also been restricted to the least expensive materials and the smallest number of items. The indispensable experiments which are less simple have been left for the class-room demonstrations. All the experiments, and the wording of the directions, have been tried under the Author's supervision with young pupils, and have been altered until found satisfactory. The lengths of the laboratory periods assigned to chemistry are so different in different institutions, varying from 45 minutes to 90 minutes and even more, that exercises arranged for any one length of period would still be a misfit in the majority of cases. To make adjustment easy, the exercises have been subdivided, so that where the whole exercise would occupy more than 45 minutes, certain parts may be omitted or assigned to the next period. It is not expected that the whole of the work outlined will be done by any one class. A choice is required, so that the interests of the instructor, the sex of the pupils, and other factors may receive consideration. One of the chief errors into which many students fall is that of doing the experiments blindly and mechanically.
