PREFACE. Some words are perhaps necessary to explain the publication of another book dealing with Elementary Electricity. A considerable portion of the present work has been in type for a long time; it was used originally as a part of the practical work in Physics for Medical Students at the Cavendish Laboratory in connexion with my lectures, and was expanded by Mr Wilberforce and Mr Fitzpatrick in one of their Laboratory Note-books of Practical Physics.
When I ceased to deliver the first year course I was asked to print my lectures for the use, primarily, of the Students attending the practical classes; the lectures on Mechanics, Heat and Light have been in type for some years. Other claims on my time have prevented the issue of the present volume until now, when it appears in response to the promise made several years ago.
Meanwhile the subject has changed; but while this is the case the elementary laws and measurements on which the science is based remain unaltered, and I trust the book may be found of service to others besides my successors at the Cavendish Laboratory.
The book is to be used in the same way as its predecessors. The apparatus for most of the Experiments is of a simple character and can be supplied at no great expense in considerable quantities.
Thus the Experiments should all, as far as possible, be carried out by the members of the class, the teacher should base his reasoning on the results actually obtained by his pupils. Ten or twelve years ago this method was far from common; the importance to a School of a Physical Laboratory is now more generally recognized; it is with the hope that the book may be of value to those who are endeavouring to put the method in practice that it is issued now.

EXTRACTS FROM PRESS NOTICES.
“Schools and Colleges will certainly benefit by adopting this book for their students.” Nature.
“Mr Glazebrook’s volumes on Heat and Light deal with these subjects from the experimental side and it is difficult to admire sufficiently the ingenuity and simplicity of many of the experiments without losing sight of the skill and judgment with which they are arranged.” Saturday Review.
“The books almost cover the advanced stages of the South Kensington prospectus and their use can certainly be recommended to all who wish to study these subjects with intelligence and thoroughness.” Schoolmaster.
“Mr Glazebrook’s great practical experience has enabled him to treat the experimental aspect of the book with unusual power and it is in this that the great value of the book as compared with most of the ordinary manuals consists.” Educational Review.
