M.Ferraud was a modest man.

That his exquisite brochure on lepidopterous insects was in nearly all the public libraries of the world only gratified, but added nothing to his vanity.
As it oftentimes happens to a man whose mind is occupied with other things, the admiral, who received M.Ferraud in the library, saw nothing in the name to kindle his recollection.

He bade the savant to be seated while he read the letter of introduction which had been written by the secretary of the navy.
"MY DEAR KILLIGREW: "This will introduce to you Monsieur Ferraud, of the butterfly fame.
He has learned of the success of your efforts in the West Indies and South America and is eager to see your collection.

Do what you can for him.

I know you will, for you certainly must have his book.
