other twenty-eight times, besides which five others- 

 passed by ; but not one took the slightest notice. 



I immersed three ants for eight hours, and then 

 put them on the strip of paper. They began to recover

 three-quarters of an hour two marked ants passed, each

 times, and three others ; but none of them took any 

 notice. 



I immersed another ant for forty minutes, and put 

 her on the strip of paper. She recovered in twenty

 teen times without taking any notice. 



I immersed two ants for ten hours, and then placed 

 them on the strip of paper. The same two marked ants 

 passed respectively eighteen and twenty-six times, and 

 one other passed by also without taking any notice. 

 After this I left off watching. 



I immersed two ants for four hours, and then put 

 them on the strip of paper. They began to recover 

 in an hour, during which two marked ants, not the 

 same as in the preceding case, passed respectively 

 twenty-eight and ten times, and two others went by ;

I immersed an ant for an hour, and then put her on 

 the same strip of paper as in the previous cases. A marked
