Repeated the experiment in which the balls were placed on glass without coating on the underside,  and in which the explosion did not pass. The result was the same as before, around the plus pole the powder was marked like a star, and around the negative pole the marks were less distinct as if the powder had been blown off.
Or perhaps I should state that the appearance around the plus pole was more rarified and [[circled]]brush[[/circled]]like than around the minus pole.

Another phenomenon was observed in this experiment and in the similar one before tried, namely the glass plate without coating being placed on the dry board of the conductor, was strongly attracted by it, and when the plate was lifted up, the powder was thrown into confusion on account of the action of the liberated electricity which had been rendered latent by the proximity of the wood. In this case it appears that the discharge of the jar in passing over the surface of the glass rendered its under surface electrified, and on account of the partial conduction of the wooden plate, the induction was shortly communicated to it, and the two were therefore held together by the dissimilar electricities of the approximate surfaces.

Sent a discharge through a surface of iron filings sprinkled [[strikethrough]] battery [[/strikethrough]] thickly over a surface of glass. The discharge left on the fillings the marks of 7 distinct routs from one pole to the other, something [[image drawn]] like the figure in the margin.
Threw off the free powder from one of the plates on which the figures of lead and sulphur wire depicted, and this way I obtained a complimentary picture, the glass was left free in broad lines around the plus pole, but in  narrow ones around the other. Around the negative pole was a kind of double border.

Repeated the experiment described above in refer to the figure with the same result. Also found that by throwing off the red lead, a kind of complimentary figure was formed.
Placed the poles on a piece of tin foil on which the sulphur and lead were strewed found no figures produced.
Placed lycopodium on the table of the discharger, sent shock from jar through, powder flashed into a blaze.

Transcription Notes:
Lycopodium powder (made from spores of club moss) is explosive and was used by photographers to produce a flash.
