A Book for the Use of Students Who Have Time to Make Experiments and Calculations

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. If I am looked upon as a person who wishes to give results to be used in faith by my pupils. It will be very easy to find many faults In this book. But I beg to say that I occupy a very different position. I aim, throughout, at showing a student how he, himself, . May attack problems which are, as yet, only partially solved, and if I give some of my own speculations, it is. Only when they are suggestive and likely to incite a student to go on with the. Study through experiment and calculation along lines which seem to me good ones.
