22 Gee, Tlie Electrical Resistance of the Hiuiian Body. 



With the application of alternating current, only 

 about 17 milliampere is required to produce muscular 

 fixation. 



Zipp^ mentions the case of a man who was rendered 

 speechless for three weeks by coining into contact with a 

 120 volt circuit. 



To so-called medical electricians the case that occurred 

 at Clothen may serve as a warning : — 



The owner of a bathing estabUshment who knew little of tlie dangers 

 attending the use of electricity, had the idea of installing an electrical bath. 



He arranged a pair of electrodes at the two ends of a slipper-bath, and 

 had them connected with a source of alternating current at 120 volts. 



Trying the effect upon his own person, at the moment of entering he 

 received a violent shock which proved fatal. 



The fatalities at the Fulham baths due to 200 volts 

 alternating current are yet fresh in our memory. 



The Board of Trade has recently revised the regu- 

 lations relating to portable electric lamps and switch 

 lamp-holders so as to minimise the danger to users of 

 electricity in factories.'^ 



Our thanks are due to a number of students at the 

 Manchester School of Technology who have given assist- 

 ance in carrying out the experiments and especially to Mr. 

 A. K. Bentley.
