Excerpt from Sound, Light and Heat This volume is an elementary text-book on Sound, Light, and Heat treated experimentally. It is essential that the experiments should be performed. The numerical results which illustrate the text, should not take the place of measurements, made by the student. The experiments demand no expensive apparatus, the aim has been to avoid elaborate instruments, descriptions of the apparatus used, appear in the book or in the Appendix, Many of the engravings are copied from pieces of apparatus in use. The experiment on p. 3 was introduced to English readers by Mr. H. G. Madan. The results obtained from the experiments make no claim to great accuracy. The student should avoid attaching to his calculations greater value than they deserve, he should consider the apparatus with which he works, it is a strong temptation to calculate to five or six places of decimals when probably not more than the first place can be relied upon. The portions of the text, between thick brackets, may be omitted on the first reading. While attempts have been made to prevent the student forming notions at variance with modern theories, little space has been given to such theories. A beginners time is best spent in examining the facts of science. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
