Introduction To Chemical Physics, Designed For The Use Of Academies, High Schools, And Colleges. Illus. With Numerous Engravings, And Containing Copious Lists Of Experiments With Directions For Preparing Them - 1873 - PREFACE - THIS Treatise has been prepwed for the use of the general reader, as well as fbr that of Students in Acacle n e, Colleges, and Medical Schools, and is designed to embody tlie most im-, poriant facts and principles of the Pllysical Forces,--I-Ient, Light, and Electricity, that have any connection wiill the productioil of Chemical phenomena, and to forin an introoduction to the study of the science of Chemistry. TiTith that science these subjects are so closely associated that they may be sail to co lstitute a part of it, and a thoroug1 h knowledge of them is ab. iolutely indi. spensab1e to its satisfactory study. They we also possessed of great intrinsic interest, and are intimately connected with all the rno - t in poi t sncti entific invent ions of the age,-the Steam Engine, Photography, the Electric Telegraph, and other., ns well a3 with many of the gent processes of Nature, in constant operation around us, and these cannot be understood without a thoroug knowledge of their elementa - y Principles. At the sanle time they are among the most difficult portior. 5 of Physicnl Science, and for their thorough uunderstnnding a considerable amount of minute explmation and illustration is required. The an thor has, therefore, treated them viths ome copiou-mess of detail, and has endeavored to avoid that meagrenods of statement which aims to present only the bare facts of science while at the same time he has sought not to exceed the limit beyond which his renders vould be unable to follow him witliout tlie aid of DIathematics. All matters of vhicll a knowledge could equally well be obtained from any good treatise on Natural Pl ilosopliy have been omitted and those points have been elucidated with special care, which a somewhat extended experience as an Instructor has shown to be peculiarly difficult of corl prehensionb y the student. The subjects wlrich hare been most carefully elaborated, are Heat lbrdiant B a the transnzissio r of Ifeat throzcgh me dia Latent Heat the Steam Engine the Chemical AzJEuence of Light Photography Spectrum Analysis the Galoanic Battery, and its Iieatiny, illuminating, chemical and rnagjzetic c f ects the Electric Tel gruph the At lantic Telegraph E leo tl 0- 4fagneticE gili est he Pire-Alann of Cities t he hduction Coils of Page and Ruhnzkorfl tile , Tag . eta-Electric Jfachines of Saxton, Page, Holmes, Tilde, and Ladd, and their various applications to Electro-Plating and Gildirzy, to the . il lurninat ion of Light-Houses, and to Nedicine.

Great pains has also been taken to trace the history of the various scientific discoveries described, and to give to their Au hon the merit which is justly their due...
