Aesop's Fables (1884)
240. The Lioness.
A controversy prevailed among the beasts of the field, as to which of the animals deserved the most credit for producing the greatest number of whelps at a birth. They rushed clamorously into the presence of the Lioness, and demanded of her the settlement of the dispute. "And you," they said, "how many sons have you at a birth?" The Lioness laughed at them, and said: "Why! I have only one; but that one is altogether a thorough-bred Lion."
The value is in the worth, not in the number.
