    (1) THE title of the first of these books is somewhat misleading. In these days of high-pressure gas and the use of burners in which the adjustment of the induced air is of the first importance, it is very natural to suppose that a work entitled “Gas Testing and Air Measurement” has something to do with gas burners. This is not the case. By gas is meant fire-damp in mines, and the air measurement refers to the ordinary practice in mines of measuring the ventilating currents.
