Excerpt from The Physics and Chemistry of Mining: An Elementary Class-Book; For the Use of Students Preparing Use of Students Preparing for the Board of Education and County Council Examination in Mining or Qualifying for Colliery Managers Certificates The students Of Mining are an ever-increasing multitude, who by present-day requirements are compelled to pay attention to at least the elements Of many branches Of modern science. The aim Of the Author, in these notes relating to the Physics and Chemistry Of Mining, is to place before the Mining Student a brief repertory of certain truths and phenomena, such as may be classed under that heading, which it is hoped may materially assist him in his studies. As a general rule, text-books on Physics and Chemistry - though Often excellent for the purposes for which they are written - deal largely with subjects which are neither interesting nor useful to the student Of Mining, and either treat very slightly or omit altogether those points which are Of special interest and importance to him. Further, there are very few books in which the principles Of those sciences are dealt with in one volume.
