bowed gaily in response to the half-friendly, half-mocking curtsey she gave him, and, turning to me again, said:

"I have a favour to ask of you, mademoiselle. Will you sit to me for your portrait?"

"I!" I exclaimed, with astonishment. "Signor Cellini, I cannot imagine why you should wish so to waste your valuable time. There is nothing in my poor physiognomy worthy of your briefest attention."

"You must pardon me, mademoiselle," he replied gravely, "if I presume to differ from you. I am exceedingly anxious to transfer your features to my canvas. I am aware that you are not in strong health, and that your face has not that roundness and colour formerly habitual to it. But I am not an admirer of the milkmaid type of beauty. Everywhere I seek for intelligence, for thought, for inward refinement—in short, mademoiselle, you have the face of one whom the inner soul consumes, and, as such, may I plead again with you to give me a little of your spare time? YOU WILL NOT REGRET IT, I ASSURE YOU."

These last words were uttered in a lower tone and with singular impressiveness. I rose from my seat and looked at him steadily; he returned me glance for glance, A strange thrill ran through me, followed by that inexplicable sensation of absolute calm that I had before experienced. I smiled—I could, not help smiling.

"I will come to-morrow," I said.

"A thousand thanks, mademoiselle! Can you be here at noon?"

I looked inquiringly at Amy, who clapped her hands with delighted enthusiasm.

"Of course! Any time you like, signor. We will arrange our excursions so that they shall not interfere with the sittings. It will be most interesting to watch the picture growing day by day. What will you call it, signor? By some fancy title?"

"It will depend on its appearance when completed," he replied, as he threw open the doors of the studio and bowed us out with his usual ceremonious politeness.

"Au revoir, madame! A demain, mademoiselle!" and the violet velvet curtains of the portiere fell softly behind us as we made our exit.

"Is there not something strange about that young man?" said Mrs. Everard, as we walked through the long gallery of the Hotel de L—— back to our own rooms. "Something fiendish or angelic, or a little of both qualities mixed up?"

"I think he is what people term PECULIAR, when they fail to understand the poetical vagaries of genius," I replied. "He is certainly very uncommon."

"Well!" continued my friend meditatively, as she contemplated her pretty mignonne face and graceful figure in a long mirror placed attractively in a corner of the hall through which we were passing; "all I can say is that I wouldn't let him paint MY portrait if he were to ask ever so! I should be scared to death. I wonder you, being so nervous, were not afraid of him."

"I thought you liked him," I said.

"So I do. So does my husband. He's awfully handsome and clever, and all that—but his conversation! There now, my dear, you must own he is slightly QUEER. Why, who but a lunatic would say that the only criticism of art is silence? Isn't that utter rubbish?"

"The only TRUE criticism," I corrected her gently.

"Well, it's all the same. How can there be any criticism at all in silence? According to his idea when we admire anything very much we ought to go round with long faces and gags on our mouths. That would be entirely ridiculous! And what was that dreadful thing he said to you?"

"I don't quite understand you," I answered; "I cannot remember his saying anything dreadful."

"Oh, I have it now," continued Amy with rapidity; "it was awful! He said you had the FACE OF ONE WHOM THE SOUL CONSUMES. You know that was most horribly mystical! And when he said it he looked—ghastly! What did he mean by it, I wonder?"

I made no answer; but I thought I knew. I changed the conversation as soon as possible, and my volatile American friend was soon absorbed in a discussion on dress and jewellery. That night was a blessed one for me; I was free from all suffering, and slept as calmly as a child, while in my dreams the face of Cellini's "Angel of life" smiled at me, and seemed to suggest peace.

CHAPTER II.

THE MYSTERIOUS POTION.

The next day, punctually at noon, according to my promise, I entered the studio. I was alone, for Amy, after some qualms of conscience respecting chaperonage, propriety, and Mrs. Grundy, had yielded to my entreaties and gone for a drive with some friends. In spite of the fears she began to entertain concerning the Mephistophelian character of Raffaello Cellini, there was one thing of which both she and I felt morally certain: namely, that no truer or more honourable gentleman than he ever walked on the earth. Under his protection the loveliest and loneliest woman that ever lived would have been perfectly safe—as safe as though she were shut up, like the princess in the fairy-tale, in a brazen tower, of which only an undiscoverable serpent possessed the key. When I arrived, the rooms were deserted, save for the presence of a magnificent Newfoundland dog, who, as I entered, rose, and shaking his shaggy body, sat down before me and offered me his huge paw, wagging his tail in the most friendly manner all the while, I at once responded to his cordial greeting, and as I stroked his noble head, I wondered where the animal had come from; for though—we had visited Signor Cellini's studio every day, there had been no sign or mention of this stately, brown-eyed, four-footed companion. I seated myself, and the dog immediately lay down at my feet, every now and then looking up at me with an affectionate glance and a renewed wagging of his tail. Glancing round the well-known room, I noticed that the picture I admired so much was veiled by a curtain of Oriental stuff, in which were embroidered threads of gold mingled with silks of various brilliant hues. On the working easel was a large square canvas, already prepared, as I supposed, for my features to be traced thereon. It was an exceedingly warm morning, and though the windows as well as the glass doors of the conservatory were wide open, I found the air of the studio very oppressive. I perceived on the table a finely-wrought decanter of Venetian glass, in which clear water sparkled temptingly. Rising from my chair, I took an antique silver goblet from the mantelpiece, filled it with the cool fluid, and was about to drink, when the cup was suddenly snatched from my hands, and the voice of Cellini, changed from its usual softness to a tone both imperious and commanding, startled me.

"Do not drink that," he said; "you must not! You dare not! I forbid you!"

I looked up at him in mute astonishment. His face was very pale, and his large dark eyes shone with suppressed excitement. Slowly my self-possession returned to me, and I said calmly:

"YOU forbid me, signor? Surely you forget yourself. What harm have I done in helping myself to a simple glass of water in your studio? You are not usually so inhospitable."

While I spoke his manner changed, the colour returned to his face, and his eyes softened—he smiled.

"Forgive me, mademoiselle, for my brusquerie. It is true I forgot myself for a moment. But you were in danger, and——"

"In danger!" I exclaimed incredulously.

"Yes, mademoiselle. This," and he held up the Venetian decanter to the light, "is not water simply. If you will observe it now with the sunshine beating full against it, I think you will perceive peculiarities in it that will assure you of my veracity."

I looked as he bade me, and saw, to my surprise, that the fluid was never actually still for a second. A sort of internal bubbling seemed to work in its centre, and curious specks and lines of crimson and gold flashed through it from time to time.

"What is it?" I asked; adding with a half-smile, "Are you the possessor of a specimen of the far-famed Aqua Tofana?"

Cellini placed the
