    another, yet shows the utmost regularity in these variations, and is therefore devoid of such sudden changes of potential as the faradic current. 5. d'Arsonval's current of high frequency and potential, which is produced by an oscillating discharge of a condenser consisting of two batteries of Leyden jars, passing through a solenoid, into the interior of which the patient is placed, who may then be traversed by a current of 3,000 Milli-amperes at the rate of 500,000 to a million oscillations per second, without perceiving a shock or any other marked sensation. 6. Morton's^ static induced current, which is produced by the aid of condensers or Leyden jars put into the circuit. The part played by the Leyden jars in this arrangement is' not simply to intensify the spark, but to act as the source of a continuously interrupted current, which is different from gal- vanism or faradism, and has been used by Morton chiefly in diseases of the spinal cord, such as talDes, muscular dystrophy, etc. Static Electricity. Static or franklinic electricity was known and medi- cally employed long before current electricity had been discovered, but lost favour when the striking phenomena connected with galvanism and faradism began to attract attention. Of recent years static electricity has, however, gradually crept back into practice, and is now considered to be a useful remedy. The induction or influence machines which have been lately constructed, and the best of which are those of Carr^, Wimshurst, and Lewandowski, yield a plentiful supply of electricity independently of the weather,' which in our damp climate is a very important consider- ation. They may be put into action either by turning with the hand, by electro-motors, or by gas engines.
