But the man of more experience showed an unresponsive expression, that was as if he remembered no conversation of any note.
"I have been told that you might be able to replace the glass in this thing out of your private stock." He presented a small, leather-covered case, evidently containing some optical instrument.

"It will give me a pretext for going," he had said to himself, as he put it into his pocket in his counting-room.

He was not going to let the apothecary know he had taken such a fancy to him.
"I do not know," replied Frowenfeld, as he touched the spring of the case; "I will see what I have." He passed into the back room, more than willing to get out of sight till he might better collect himself.
"I do not keep these things for sale," said he as he went.
"Sir ?" asked the Creole, as if he had not understood, and followed through the open door.
"Is this what that lady was getting ?" he asked, touching the remnant of the basil in the box.
"Yes, sir," said the apothecary, with his face in the drawer of a table.
"They had no carriage with them." The Creole spoke with his back turned, at the same time running his eyes along a shelf of books.

Frowenfeld made only the sound of rejecting bits of crystal and taking up others.
"I do not know who they are," ventured the merchant.

Frowenfeld put up his materials.
"Mr.Frowenfeld, are these your books?
I mean do you use these books ?" "Yes, sir." The Creole stepped back to the door.
"Agricola!" "_Quoi_!" "_Vien ici_." Citizen Fusilier entered, followed by a small volley of retorts from those with whom he had been disputing, and who rose as he did.

The stranger said something very sprightly in French, running the back of one finger down the rank of books, and a lively dialogue followed.
"You must be a great scholar," said the unknown by and by, addressing the apothecary.
"He is a professor of chimistry," said the old man.
"I am nothing, as yet, but a student," said Joseph, as the three returned into the shop; "certainly not a scholar, and still less a professor." He spoke with a new quietness of manner that made the younger Creole turn upon him a pleasant look.
"H-my young friend," said the patriarch, turning toward Joseph with a tremendous frown, "when I, Agricola Fusilier, pronounce you a professor, you are a professor.
