He increased or diminished each day the proportion of water to be consumed by his patients, which made them feel perfect confidence in the care taken of them by him.

"We stopped yesterday at two glasses and three-quarters," he would say; "well, to-day we shall only take two glasses and a half, and to-morrow three glasses. Don't forget! To-morrow, three glasses. I am very, very particular about it!"

And all the patients were convinced that he was very particular about it, indeed.

In order not to forget these figures and fractions of figures, he wrote them down in a memorandum-book, in order that he might never make a mistake. For the patient does not pardon a mistake of a single half-glass. He regulated and modified with equal minuteness the duration of the daily baths in virtue of principles known only to himself.

Doctor Latonne, jealous and exasperated, disdainfully shrugged his shoulders, and declared: "This is a swindler!" His hatred against Doctor Black had even led him occasionally to run down the mineral waters. "Since we can scarcely tell how they act, it is quite impossible to prescribe every day modifications of the dose, which any therapeutic law cannot regulate. Proceedings of this kind do the greatest injury to medicine."

Doctor Honorat contented himself with smiling. He always took care to forget, five minutes after a consultation, the number of glasses which he had ordered. "Two more or less," said he to Gontran in his hours of gaiety, "there is only the spring to take notice of it; and yet this scarcely incommodes it!" The only wicked pleasantry that he permitted himself on his religious brother-physician consisted in describing him as "the doctor of the Holy Sitting-Bath." His jealousy was of the prudent, sly, and tranquil kind.

He added sometimes: "Oh, as for him, he knows the patient thoroughly; and this is often better than to know the disease!"

But lo! there arrived one morning at the hotel of Mont Oriol a noble Spanish family, the Duke and Duchess of Ramas-Aldavarra, who brought with her her own physician, an Italian, Doctor Mazelli from Milan. He was a man of thirty, a tall, thin, very handsome young fellow, wearing only mustaches. From the first evening, he made a conquest of the table d'hôte, for the Duke, a melancholy man, attacked with monstrous obesity, had a horror of isolation, and desired to take his meals in the same dining-room as the other patients. Doctor Mazelli already knew by their names almost all the frequenters of the hotel; he had a kindly word for every man, a compliment for every woman, a smile even for every servant.

Placed at the right-hand side of the Duchess, a beautiful woman of between thirty-five and forty, with a pale complexion, black eyes, blue-black hair, he would say to her as each dish came round:

"Very little," or else, "No, not this," or else, "Yes, take some of that." And he would himself pour out the liquid which she was to drink with very great care, measuring exactly the proportions of wine and water which he mingled.
