88 LOCALIZED ELECTRIZATION. 



that muscle contract en masse is nearly that which he saw me 

 practise in 1852 (without then understanding it). I say nearly, 

 because Kemak states that he places only one rheophore on the 

 branch of the accessory nerve of Willis, while the other is placed 

 on a point of the muscle. But it is impossible to produce con- 

 traction of all the parts constituting the trapezius except by 

 placing the rheophores on the points of the cervical border of the 

 muscle at which the two trapezian nerves penetrate : the one on 

 the trapezian branch of the spinal (five centimetres above the 

 clavicle), the other below the trapezian branch of the cervical 

 plexus (three centimetres above the clavicle). Then, on the side 

 excited, we see the head inclined, the shoulder raised, and the 

 scapula drawn towards the median line : then we see the three por- 

 tions of the muscle swell, and stand out in relief beneath the skin. 



In 1805 ^ I wrote : " This work (in which would be shown the 

 anatomical points on which the rheophores should be placed, in 

 order to study the proper action of muscles or of their divisions) 

 would certainly be very useful ; but, with the desire to shorten it 

 as much as possible, and to facilitate study, I intend to set forth 

 the data, at some future time, in a synoptical table with figures. 

 This project cannot be put in execution until I have entirely 

 terminated my researches on muscular electro-j^hysiology."^ 



Taking up my idea, and desirous, without doubt, to put it more 

 quickly in execution, a G-ermau writer, Dr. Ziemssen,^ has shown 

 on anatomical plates the points on which the rheophores should be 

 placed to produce isolated contraction of muscles ; declaring, in the 

 preface to his book, that he wishes to render the employment of 

 my method of muscular electrization easy to every practitioner. 



We must not praise this work too much ; for the writer unfor- 

 tunately has fallen under the influence of the errors of Remak. 

 He says that the method consists solely in always placing the 

 rheophores over the points of immersion. Nothing, certainly, can 

 be more simple and more easy than this ; for which he has only 

 needed to use certain anatomical plates, as I had advised in my 

 reply to M. Eemak. (The points of immersion of the nerves are 

 shown with the greatest exactitude in the plates of M. Ludovic 

 iiirsfhfeld.* As these are drawn to half the natural size of an
