Record OF observations. All original observations are to be entered in the regulation notebook at the time they are made. The uniform observance of this rule will save annoyance from simple mistakes due to carelessness or haste, which are frequently made even by the-best observers, and which, without the original observations, it would be impossible to correct. It is a saving in the end to devote enough time to the origi nal records to make them neat and clear, and so complete and logically arranged as to enable any person who is familiar with the experiment to understand the meaning of each figure recorded. In all cases it is the original observations that are to be recorded. A derived result should in no case be recorded as an observation, no matter how simple may be the process of derivation.
