“Your grandmother might perhaps go and sit, if the Doctor allows it, in some quiet path in the Champs-Élysées, near that laurel shrubbery where you used to play when you were little,” said my mother to me, thus indirectly consulting Dr. du Boulbon, her voice for that reason assuming a tone of timid deference which it would not have had if she had been addressing me alone. The Doctor turned to my grandmother and, being apparently as well-read in literature as in science, adjured her as follows: “Go to the Champs-Élysées, Madame, to the laurel shrubbery which your grandson loves. The laurel you will find health-giving. It purifies. After he had exterminated the serpent Python, it was with a bough of laurel in his hand that Apollo made his entry into Delphi. He sought thus to guard himself from the deadly germs of the venomous monster. So you see that the laurel is the most ancient, the most venerable and, I will add⁠—what is of therapeutic as well as of prophylactic value⁠—the most beautiful of antiseptics.”
