The Electrified Ball

Place an ivory ball on the prime conductor of the machine, and take a

strong spark, or send the charge of a Leyden phial through its centre,

and the ball will appear perfectly luminous; but if the charge be not

sent through the centre, it will pass over the surface of the ball and

singe it. A spark made to pass through a ball of box-wood, not only

illuminates the whole, but makes it appear of a beautiful crimson, or

rather a fine scarlet colour.
