INDUCED ELECTRICITY. 37 



ehdrization ; and that of contact electricity, galvanization. But 

 this hist word has, in general, been employed indifferently in 

 medical practice, to denote the use of either contact or induced 

 electricity. The electro-pliysiological and electro-therapeutical 

 considerations above laid down will render plain the disastrous 

 effects of such confusion. 



Since, then, it is necessary to coin a word to express exactly 

 induced electricity and its application, may we not take the word 

 from the name of the discoverer? The name of Galvani has 

 been given to contact electricity; and I would give to induced 

 electricity the name of Faraday. Thus induced electricity itself 

 may be called faradism ; and its employment may be called 

 faradization. Such a nomenclature seems to me to be the more 

 happy, since it not only establishes a well-marked distinction 

 between induced and contact electricity, but also does honour to 

 the name of a philosopher to whom medicine is indebted for a 

 discovery far more valuable in therapeutics than that of Galvani." 



[Mr. J. Netten Eadcliffe has taken objection to the nomenclature adopted 

 by Duchenne in respect of the application of " frictional " and " contact elec- 

 tricity " to medical purposes. The use of the word electrization, sometimes in 

 a general, sometimes in a special and limited sense, is, he thinks, apt to 

 confuse. The terms "frictional electricity " and " static electricify " are words, 

 moreover, passing into disuse among physicists ; while the terms " contact 

 electricity" and "r/alvanism" are almost entirely disused in physical science. 

 Mr. Eadcliffe thinks that it would be an advantage to have a series of terms 

 which, while securing the object which Diichenne had in view, would 

 not clash with the nomenclature adoj^ted by physicists. He writes, " The 

 electricity of chemical action (' contact electricity,' ' galvanism,' so-called) 

 is more correctly and generally designated after the name of the original 

 discoverer, Volta, voltaic electricity. Faraday suggested that frictional elec- 

 tricity should be termed after the illustrious philosopher Franklin, whose 

 name is especially connected with its early experimental study, fmnklinic 

 electricity, and the name is now being widely adopted by physicists. By 

 applying the meihod of terminology which Duchenne has so happily used 

 in respect of the induced current, to other forms of electricity, a series of 

 terms is obtained which wonld be accurate in form as the practice of nomen- 

 clature goes, true to science in fact, free from confusion, and particularly 

 convenient in usage. The series would be (1) faradaic electricity, or fara- 

 dism. ; and, as respects the pathological and therapeutical application of the 

 agency, faradization ; (2) voltaic electricity, or voltaism ; voltaization ; (3) 

 frariMinic electricity, ov fratiklinism ; franklinization." — (' The Practitioner'

" At present, the above nomenclature I although MM. Becquerel have maiu-' 

 is universally used in practical medicine, j tained that it was not acceptable.
