" To all students and many teachers of the subject this masterly volume will 

 be welcome. . . . A complete exposition of the subject." — Saturday Review. 



" In this comprehensive little volume Professor Tait has gathered together all 

 the chief known physical facts about light, for the use of ordinary students who 

 do not desire to take up the subject in any special detail. It bears the impress 

 of his exceptionally logical and orderly mind, and his wide power in cosmical 

 envisagement. For example, at the very outset, in dealing with the sources of 

 light. Professor Tait enumerates such classes as the potential energy of gravita- 

 tion of scattered masses, the kinetic energy of current electricity, the potential 

 energy of chemical affinity, and so forth." — Pall Mall Gazette. 



"Thorough and interesting treatise." — Glasgow Herald.
