SOUND, LIGHT, AND HEAT. 



By Mark R. Wright, author of "Elementary Physics." With 162 Illus- 

 trations and -Diagrams. i2mo. 272 pages. 80 cents. 



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. Examples are 

 given frequently throughout the work.

 Science.) i2mo. 357 pages. $1.50. 



The aim of this book is to exhibit the scientific connection of the various 

 steps by which our knowledge of the Phenomena of Heat has been extended. 

 It treats of Thermometry, Calorimetry, Lines of Equal Temperature on the 

 Indicator Diagram, Adiabatic Lines, Heat Engines, Latent Heat, Thermo- 

 dynamics of Gases, Free Expansion, Determination of Heights by the Barom- 

 eter, Radiation, Convection Currents, Diffusion of Heat by Conduction, 

 Diffusion of Fluids, Capillarity, Elasticity and Viscosity, Molecular Theory of 

 the Constitution of Bodies, etc., etc.
