Excerpt from An Elementary Treatise: On Qualitative Chemistry Analysis Provide a well-bound notebook for the subject and use it for nothing else. Keep accurate and methodical records of all experiments performed. These records should be made during or immediately following the performance of the experiment, and not transferred or erased afterwards. Original notes of an unsuccessful experiment are more valuable than a well-written description of a successful experiment, if the latter is composed in the absence of the experiment.
