Burns are produced either from an arc or by the heating 

 of the tissues of the body by the current. In case burns 

 are produced it is very necessary not to touch or irritate 

 them. They should be protected from the air by a soft 

 dressing, such as carron oil (a mixture of limewater and 

 linseed oil), baking soda (teaspoonful to a pint of water), 

 or a paste of flour and water. A dry or charred wound should 

 never be covered by a liquid dressing, but simply with a 

 clean cloth.
