 traction, took place according to any definite ratio. 

 It would also, as observed by Matteucci, be ex- 

 tremely important, " de s'assurer si I'activite de I'Drgane 

 electrique de la torpille qui ne donne lieu qu'a une 

 decharge electrique, sans chaleur et sans travail 

 mecanique (contraction), est accompagnee ou non 

 d'un phenomene analogue a la respiration musculaire. 

 L'experience est difi&cile mais important."
