Originally published in 1901, this book was intended for students of physics to become acquainted with the principles and methods of accurate measurement in laboratories. Aimed as a reference guide for undergraduates to develop and reinforce their understanding of elementary physics, the book is divided into six sections: preliminary, general physics, heat, sound, light, and magnetism and electricity. Within each of these sections, multiple experiments are contained and instructions are provided on how to carry out each experiment, whilst notes are also provided for teachers on how to measure and check accurately the results obtained. Multiple diagrams and tables are also included throughout to assist with learning. This book will be a valuable resource to students, teachers and researchers of physics and to anyone with an interest in the history of science education.
