NO EVIDENCE OF SEPARATE SENSE OF DIRECTION. 271 



" I may add that, while in Germany a few weeks ago, 

 I tried on several species of ant the same experiments 

 as Sir John Lubbock describes in his paper as having 

 been tried by him upon English species, and here also I 

 obtained identical results; in all cases the ants were 

 hopelessly lost if liberated more than a moderate dis- 

 tance from their nest. 



M. Romanes' experiments, therefore, as he himself 

 says, entirely confirm the opinion I have ventured to 

 express — ^that there is no sufficient evidence among 

 insects of anything which can justly be called a " sense 

 of direction."
