THE HORSE

Figure 116. — Brown Bat. 
Notice how the wings of the bat are formed. Membranes are stretched 
between the bones of the fingers, between the arms and legs, and between 
the legs and tail. This entire structure is known as the wing of the bat. 
How does it differ from the wing of a bird ? What other special adaptations 
do you see ? 
Figure 117. — Bat Hibernating. 
During the winter sleep the bat hangs 
suspended in some cave.
