'To the devil with all your science!' he exclaimed; 'she is dying, do you hear me? She is dying! and you have nothing better to propose than three ounces of snails and a plaster of cow's dung! Rascals, charlatans, fools! I will hang every one of you!'

He paced the room a prey to mortal anguish, listening to the sufferer's unceasing groans. Suddenly his eye fell on Leonardo and he drew him aside.

'Listen,' he cried wildly, 'Leonardo, you are master of great secrets. No, no, deny it not, I know. Ah, my God! my God!—that cry! What was I saying? Yes, yes! Help me, Leonardo! Do something! I would give my soul to succour her—even for a short space—only to still that cry!'

'Oh God, where are my thoughts!' cried the Duke bethinking himself. 'I must be going mad! God help me!' And he fell a-praying with renewed fervour; but now visions of Leonardo's crystal globes tormented him, and the tiresome chant of the gilded boy—
