Seeds of Peach, 
Nectarines, and 
Almond 
The picture shows 
the stone of the nec- 
tarine at the left, two 
peach stones in the center, 
and the almond stone at 
the right. Note the thin 
shell of the latter in com- 
parison with the former. 
Doubtless the difference is 
due to selective breeding 
through countless 
generations,
