A Sixth Sense 



HEAD OF THE LONG-EARED BAT. 



This bat has two wing-like leaves of great sensitiveness in front of the 

 ears. These are very much like the wings of the insect which it pursues. The 

 ears themselves are only able to hear rather high notes, but these two little 

 leaves vibrate in unison with very low notes, much lower than the human ear 

 is able to take in. It is therefore possible for this bat to pursue and capture 

 insects in the dark without seeing them. The little leaves really endow the animal 

 with a sixth sense. 



HEAD OF THE AFRICAN MAGADERM. 



This bat has very large ears, and is also provided with a sensitive organ 

 attached to the nose. It is a very fierce little beast in fact, a species of a 

 vampire, and feeds not only on insects, but it kills and devours other bats.
