Abstract
THIS constitutes a new edition, the third, of the first volume of a series intended to cover modern practice in coal mining, this particular volume describing the occurrence and properties of coal, the methods of searching for coal by means of boring and deep boring in general. The body of the work has not been greatly altered from the previous edition, but an additional chapter has been inserted in which some modern appliances and devices for determining the deviation: of boreholes are described. The consequence of this method of dealing with the subject is that the body of the work remains somewhat out-of-date. For example, the bomb calorimeter is not even mentioned, though it is to-day the most generally used appliance for deter mining the calorific power of coal. Although not a matter of technical importance, a protest may well be entered against such an irritating piece of false Latinity as “apparati”.
