NERVE EXCHANGES

I _ | BODY’S TELEPHONE SYSTEM. I The system 'ff carrying messages 1 from one point of .the human body Io [another is made up of hundreds of delicate fibres, each ibomt-one-tenth the [thickness of a hum;an hair. The exchanges that, connect the fibres or lines |are the brain and the spina! cord. Il is a system of astonbhiing perfection, but, [like its Post Office-counterpart, subject to “wrong number'’, “line busy,” ami • ‘line, out of order” troubles. I Nerve messages are carried either to I our muscles or-to fiur nervous system at | the rate of 400 ft r second. Human efjficiency mainly consists in the perfect [working of this system. The hand which I responds to a call a hundredth part of | a second quicker tiuui another hand will i eventually belong -o the man who has ■outstripped his fello’ws in his own call--1 ' n £- Electric currents are powerful stimulating agents of the .-.nerves. They have the elfect of recharging the battery of the body’s telephone system. High frequency currents even of a million I volts, voltages that -would prove fal;d if they were of ho; frequency, can In passed with complete safety into the body. The reason is that these cur rents, similar to tkwe used in wireless.] oscillate so rapidly that their ill-effect , is neutralised or reversed before any. fatal effect is produced by the changeover of the cuiner.t.
