Excerpt from Exercises in Chemistry, Systematically Arranged to Accompany: Second Revised Edition of an Elementary Study of Chemistry
Be economical. Reagents are expensive, and someone must pay the bills. Experiments nearly always go better with small quantities than with large ones, and are more quickly carried out. 'every good chemist works with the smallest quantities possible - partly to save money, but 'more largely to save time and learn more. Stick to the quantities specified in the notes. Actually weigh or measure these quantities until you can guess very closely how much a gram or a cubic centimeter really is.

Excerpt from Exercises in Chemistry, Systematically Arranged to Accompany: Second Revised Edition of an Elementary Study of Chemistry
The laboratory is a place for seeing, but it is equally a place for thinking. The laboratory course will include a certain amount of work that is largely mechanical, such as bending and sealing glass tubes, but in the main it is headwork rather than handwork that counts. Each experiment is designed to bring out an important fact or to illustrate some principle. Be sure you grasp the meaning of the experiment before you start upon it. Study the directions with the same care that you would give to an assignment in the textbook for recitation.
Keep your desk neat and clean. A glance at a student's work desk will usually tell an experienced teacher exactly what kind of work is being done at it. A dirty desk, littered with unnecessary articles and with apparatus awkwardly put to gether, almost surely indicates a lack of understanding of the work in hand and a willingness to accept without question any thing the book says. A clean desk and well-connected appara tus indicate clear thinking and real joy in the work. Be determined to prove the truth of things for yourself.
Get ready for an experiment before you start it. In addition to your burner, have at hand all the materials called for at the beginning of the directions for each experiment. There will be four or five bottles of the most-used reagents on your desk, and' the others will be on the shelf for general use.
