"My dear friend," said the illustrious Gaudissart to Finot, "it is
admirably written. Thunder and lightning! we are in the upper regions
of science. We shirk nothing; we go straight to the point. That's useful
literature; I congratulate you."

"A noble prospectus!" cried Popinot, enthusiastically.

"A prospectus which slays Macassar at the first word," continued
Gaudissart, rising with a magisterial air to deliver the following
