IN FEATHERS AND FUR.

A WALKING STOMACH. 
It don't look like a stomach, I must admit ; it looks more like 
a little plant Here it is. The small figure (No. 2) is the creature 
the size of life, while the large one (No. 1) is as it looks under the 
microscope. 
The name of this strange and wonderful animal is Hydra 
Viridis, and it lives in ponds and ditches, either attached to the 
under side of the leaf of a water plant, or to a bit of floating wood. 
It is not always attached to something, however. It can walk about, 
though not very nimbly, and it likes best to hold on to the shell of 
a fresh water snail, and thus get carried about.
