TWO YOUNG NATURALISTS. 



Du Tremblay did not with this end his interesting 

 discoveries. " Since out of one Hydra you can make 

 two," he sagely reasoned, "out of two probably one 

 can be made." This was both said and done, and the 

 patient naturalist, after some unsuccessful efforts, 

 succeeded in fastening together several hydras, end 

 to end, in such a way as to merge their several indi- 

 vidualities in one. 



And thus we see that in the most unfavourable 

 localities the naturalist need never weary.
