Federico came in, panting.

"What has happened?"

My mother, still bending over the cradle, cried out:

"The baby is dying."

Federico ran up and looked:

"He is choking," he said. "Don't you see? He has stopped breathing."

And he seized the child, took it from the cradle, raised it and shook it.

"No, no! What are you doing? You will kill him!" cried my mother.

At this moment the door opened, and a voice announced:

"The doctor."
