NOTE BY THE TEANSLATOR. 



This translation is made from the third edition of the original 

 Work, now in course of passing through the press. The present 

 Part includes all that had been printed at the time of the invest- 

 ment of Paris by the German army, and, in consequence of that 

 investment, it is published before the original is given to the 

 world. 



Duchenne's great work on 'Localized Electrization' is not only 

 a well-nigh exhaustive treatise on the medical uses of electricity, 

 but it is also an elaborate exposition of the different diseases in 

 which electricity has proved to be of value as a therapeutical 

 and diagnostic agent. No similar treatise exists in the English 

 language : indeed the work is unique. 



It has not been without hesitation that I have ventured to add 

 certain notes to the original. These additions have been made 

 with strict reference to the requirements of English medical prac- 

 titioners, and they have particularly in view to facilitate the 

 practice of medical electricity. In making them, I have been 

 guided partly by the large experience of the National Hospital 

 for the Paralysed and Epileptic, and partly by the observations 

 derived from private practice.
