Williams' A Simple Treatise on Heat.
By W. Mattieu Williams, F.R.A.S., F.C.S.
"This is an unpretending little work, put forth for the purpose of expounding in simple style the phenomena and laws of heat. No strength is vainly spent in endeavouring to present a mathematical view of the subject. The author passes over the ordinary range of matter to be found in most elementary treatises on heat, and enlarges upon the applications of the principles of his science—a subject which is naturally attractive to the uninitiated. Mr. Williams's object has been well carried out, and his little book may be recommended to those who care to study this interesting branch of physics."—Popular Science Review.
