CHAPTER XIX. 
MAN’S NEAR RELATIVES (MAMMALS). 
With slight variations, the questions which follow 
can be made to apply to many other animals than the 
cat. With the limited time usually allowed for the 
study of mammalia, abundant material among common 
domesticated animals is easily within the reach of all 
pupils. 
The Living Cat. With what is the body covered ? 
Do you find the same parts of fore and hind limbs as 
in the frog ? 
How many toes has the cat on the fore foot ? on the 
hind foot ? 
Can the claws of the cat be withdrawn ? 
Can the claws of a dog be withdrawn ? 
On your own hands where are the parts correspond¬ 
ing to the pads on the fore foot of the cat ? 
Can you find the cat’s elbow, wrist, knee, and heel ? 
Does the cat ever walk or creep with the heel touch¬ 
ing the ground ? 
In the human body the tendon of Achilles is the 
strong band connecting the heel with the muscles of 
the calf of the leg. Can you find this tendon in the 
cat ? 
Are the cat’s vertebrae capable of more or less motion 
than those of the frog ? Than those of a bird ? 
Do the vertebrae extend into the tail ? 
Does the sternum seem as large as in most birds ? 
Why should there be a difference ?
