Excerpt from The Elements of Laboratory Work: A Course of Natural Science
The course of work described in the following pages forms an introduction to all branches of Natural Science. The elementary nature of the book has caused me to pay more attention to method than to detail. Every student will need to follow closely and thoughtfully the performance of each experiment, in nearly all cases making his own observations and measurements, in order that the capacity for independent judgment, as well as an interest in original research, may be awakened at the outset. When a fact or law, discovered by means of a student"s own personal observation and intelligence, turns out to be very familiar to others more advanced, the value of the research to the student himself is but slightly impaired.
Each section conveys a definite lesson, and care has been taken that they may follow in inductive sequence. It is important that each experiment and each stage of the course be described and reviewed at length in the students notebook, which should contain many practical details omitted from the text-book, not only lest they should obscure the more important outlines of work, but also because it is intended that some freedom and originality in manipulation should be encouraged.
