ABBE NOLLET EXHIBITING GRAY'S EXPERIMENT OF THE 

 ELECTRIFIED BOY. 1 



1 Reproduced in fac simile from the frontispiece of Nollet's Essai sur 

 re"lectricite* des corps. Paris, 1746. The boy is suspended on silk lines 

 and electrified by the excited glass tube held by the lecturer, so that his 

 hand attracts bits of loose foil on the table below.
