Excerpt from An Intermediate Course of Practical Physics This book was originally written to assist students preparing for the Intermediate 380. And First m.e. Examinations of the Victoria University; but the requirements of these examinations are so nearly identical with those Of other Universities, and the courses of Practical Physics given in Public, Technical, and other Schools, cover so nearly the same ground, that it is hoped it will prove useful to a wider circle of students. The term Intermediate in the title of the book, has been used to indicate that its standard is higher than that of the Elementary Text Books; but it is by no means essential that students should have worked through an elementary book in order to perform the exercises described in this volume. The book is in the main, a reprint of the papers of instructions which have been issued to the students of the Owens College during the last five years.
