greater in the hand of father than of mother. The same is 
true of the hand of daughter. When she grows to maturity, 
this distance will be much greater than it is in the hand of her 
mother. The daughter inherits this peculiarity in her hand 
from her father. 
Make a study of the several parts of your own hand and 
compare your hand with the hand of your mother and father. 
Figure 439 . — Heredity Shown by Comparison. 
Photograph of hand of father at the left, of mother on the right, and of 
daughter in the middle. Which parts of the daughter’s hand are like her 
mother’s ? Which like her father’s ? 
This study will show you what is meant by the term heredity 
as applied to your hand. 
In a similar manner you can compare the color of your 
eyes and hair; length of arm; shape of head; muscular vigor; 
size of body; intellectual traits, such as interest in language, 
history, science, or business; and temperament, which 
includes liveliness, deliberateness, excitability, quickness, or 
slowness.
