Girard, Maurice. Note relative h des experiences sur Paction 
des courants electriques sur les Chrysalides des Lepidopteres. 
Annales Soc. Ent. France, 4® serie, tome vi. pp. 207-212. 
The author has repeated Wagner^s experiments on the in- 
fluence of electric currents upon chrysalids, employing, instead 
of Vanessa urticce, Papilio machaon and Orgyia pudibunda. He 
finds that when the conducting- wires are applied to the surface 
of the chrysalids no currents pass through them, and suggests 
that the alterations recorded by Wagner as produced in the 
Butterflies evolved from those experimented on by him are due, 
not to the action of the currents, but to the effects of the mani- 
pulation to which they were subjected.
