New (2d) Edition 



Tousey's Electricity, X-Rays and Radium 



The revision for this second edition has been unnsnally severe in order to bring it into 

 accord with the great advances of the last few years. Over 100 pages of new matter have 

 been added, and 60 new illiistrations—Buch new matter as diathermy, sinusoidal currents, 

 radiography with intensifying screens, rontgenotherapy, the Coolidge and similar rontgen 

 tubes, Tousey's own dosage, and radium therapy. M«ohado's tabular classifications of 

 electric methods, effects and uses, have also been included — every advance in these mod- 

 ern therapeutic agents. The work is complete. It explains away all difficulties in using 

 these modern means of diagnosis and treatment. Nothing is taken for granted ; every 

 detail is explained from reading the radiogram down to the formula of the soldering com- 

 pound used in making wire connections. It represents the present-day knowledge of this 

 new and important branch of medical science. k-^~, - ^„."
