One ball is placed in connexion with the po- sitive and the other with the negative conductor, when the passage of the electric fluid from the for- mer to the latter ignites the phosphorus, fig. 122.... 1 1 Improved Electrical Condensor and Apparatus, for ex- periments upon disguised or paralysed electricity, consisting of two circular metallic plates, 12 inches diameter, insulated by glass supports, one of which is made to slide in order that they may be brought near or made to recede from each other. A binding screw is attached to each plate to connect with a pith ball or gold-leaf electroscope, fig. 123..... coe 2 8 Giass Jars mounted with moveable metallic coatings, to show that the charge is not in the coatings, as those with which it is charged may be removed and others put in their place while the glass retains the electri- Adams’s combined Apparatus, consisting of ball and wire, pointed wire, exhausting syringe, luminous conductor, exhausted flask, two Leyden jars and insulating pillar.
