he poured the liquid into a crucible,
set it among the glowing and sparkling coals and murmured strange words
and spells over the seething fluid until it boiled up and the hissing
bubbles ran over the rim of the crucible. Then he stood the hot vessel in
cold water, pronounced one more incantation over it, held it before a
mirror--the symbol of the Spirit of Truth and the emblem which she is
always represented as carrying in her right hand--and poured the liquid
back into the phial. Beads of perspiration stood on his forehead, his
eyes gleamed with excitement, and he breathed heavily as he approached
his son to try the power of the new elixir on him.

But something most unexpected happened: Frau Schimmel, usually so timid,
pressed the boy's face against her breast and, her good gray eyes
flashing with her angry determination to resist, cried out "Do with your

she could not say whether he looked more like a madman or a saint as he
finally lifted his arms towards heaven and cried: "I have found it,
Father, Bianca!--I have found it!"

Frau Schimmel left him alone and put the child to bed. When she returned
to the laboratory and found the doctor in the same place where she had
left him, she said modestly: "Here I am and if it pleases the Herr Doctor
to try the elixir on so humble a person as myself, I am at his service.
Only one favour would I ask: would the Herr Doctor be so kind as not to
ask questions about Schimmel and myself or any member of the honoured
Ueberhell family."

But the doctor hesitated awhile before accepting this offer, for he had
not forgotten the defiant words with which she had withheld his child
from him only a sho
