the ball screwed on, and if the ball be placed on the 

 flesh, and a person holding the tube move it about, 

 the ball will roll wherever it is directed, Now to 

 apply the electric current : [hook one end of the 

 covered spring wire to the ring of wire at one pole, 

 and the other end to the ring of one wire in the glass 

 tube, as the same with the other spring wire and con- 

 tents of the other glass tube; it will be obvious tbat 

 a person holding the gUiss tubes, one in each hand, he 

 being thus insulated, will be able to pass the electric 

 current in any direction, as whatever intervened be- 

 tween those two balls would receive it, and by the 

 balls having a rotary motion, this agent can be applied 

 more extensively and with less of pain. The part 

 being moistened with a little compound soap liniment 

 will render the application more powerful. 



The liquid I use is in the proportion of one ounce 

 of strong sulphuric acid to thirty ounces of distilled 

 water, and the necessary quantity can be kept always 

 ready for use in a well-stoppered bottle. The metals, 

 as soon as used, should be washed in clean, tolerably 

 warm water, the reason of which is, because they dry 

 sooner, particularly if placed before the fire, and 

 when dry they should be protected from the air. 



In cases of suspended animation the current of 

 electricity can be applied by this mode up and down 

 the spine, and in every direction.
