Book excerpt: Excerpt from An Elementary Laboratory Course in Chemistry The course of practical chemistry outlined in this book is intended for students who are beginning the subject and at the same time taking a course of lectures on general chemistry. It was arranged primarily for the first year Arts course of the University of Toronto, in which all science students - whether they are taking chemistry for two years only or whether they intend to specialise in this subject - are required to do exactly the same work in their first year. It has been necessary therefore to keep in view the twofold object of giving the former class of students, in a very limited period, as fair an idea as possible of the general nature of chemistry, and at the same time, of providing the latter class with a good working basis for their subsequent course. Owing to the short time spent in the laboratory (two afternoons a week) many important principles have been necessarily omitted. The principles especially emphasised, however, are those which, on account of their inherent difficulty or of some traditional error in previous instruction, generally appear to give most trouble to the student. Particular emphasis has been laid on the importance of the quantitative side of chemistry. Where purely qualitative experiments have been introduced it has been done largely with a view to relieving the over-crowding at a too limited number of balances (one to five students). Especial attention has also been given to the method of note-keeping in the laboratory, as it is believed that the habit of accurately and honestly recording all observations is one of the most important results of a laboratory training. The use of Arabic numerals has been avoided in numbering the experiments and sections of the book, so as to prevent confusion with the student's individual system of numbering in his note book, where Arabic figures are the more convenient. Although much has necessarily been left to personal instruction, it is intended that the student shall follow all the directions given in the book. These have been purposely distributed among the theoretical discussions so that they cannot be found without careful reading. More concise explanations of some of the fundamental principles, together with a few extra experiments, are given in the appendix. With a view to encouraging resourcefulness, the apparatus used has been restricted to the simplest possible kind. The experiments on qualitative analysis (pages 50-58) are intended only to show the principles and difficulties of such work.
