+Fran.+ All's safe: he takes that way. Let him, a God's name, Follow his nose to the perfuming-room. +Blan.+ He'll fright poor Silvia out of her wits; But I'll come to her succour with a peal Will ring him. [_Exeunt +Donna Blanca+ and +Francisca+._ _Scene changes to the laboratory. Here is to open a curious scene of a laboratory in perspective, with a fountain in it, some stills, many shelves, with pots of porcelain and glasses, with pictures above them: the room paved with black and white marble, with a prospect through pillars at the end, discovering the full moon, and by its light a perspective of orange-trees, and towards that farther end +Elvira+ appears at a table, shifting flowers, her back turned._ _Enter +Don Zancho+ hastily: +Elvira+ turning about, they both startle, and stand awhile as it were amazed._ +Don Z.+ O heavens! what is't I see? 'Tis mere illusion, Or 'tis the devil in that angel's form, Come here to finish by another hand The fatal work that she began upon me By Don Fernando's. +Elv.+ Good gods! Don Zancho here! it cannot be! Or 'tis his ghost, come to revenge his death On its occasioner; for, were he alive, He could not but have more humanity Than (having been my ruin at Madrid, And robb'd me of my home and honour there) To envy me an obscure shelter here. [_Whilst they amazed step back from one another, enter +Don Julio+, who, seeing +Don Zancho+ with his back towards him, drawing his sword, says_-- +Don J.+ Think not (whoe'er thou art), by flying thus From room to room, to 'scape my just revenge. Shouldst thou retire to th' centre of the earth, This sword should find thee there, and pierce thy heart. [_Throwing down the candle, he makes towards +Don Zancho+; but upon his turning about towards him, he makes a little stop, and says_-- Nay then, if it be you, I'm happy yet In my misfortune, since the gods thus give me The means at once, and by the self-same stroke, To right my honour, and revenge my friend; And, by that action, fully to comply With what the Duke requires in the behalf Of wrong'd Don Pedro. [_+Don Julio+ makes at +Don Zancho+: he draws, and they begin to fight; +Elvira+ crying out_, Help! help! _runs to part them, and they stop upon her interposing._ _Enter +Don Fernando+ hastily over the stage, as coming from the private apartment._ +Don F.+ I hear an outcry and [a] clattering of swords. My friend (engag'd) must find me by his side. [_Exit, and re-enters at another door._ [_As +Fernando+ comes to the door of the perfuming-room, seeing them at a stand, he stops and stands close._
