The next point in the opera which excited the special enthusiasm of the house was the impassioned finale to the second act, in which Amina on her knees strives to convince her lover of her innocence of having ever harboured a thought inconsistent with entire devotion to him. She sang as if her whole soul were in her words; and the entire theatre was electrified by the power of her acting; the entire theatre, with the exception of one intelligent and observant little face in a box on the upper tier, exactly opposite to that of the Marchese Lamberto. From that vantage-ground of observation Paolina saw perfectly well both the singer on the stage and the Marchese in the box; and again felt sure that the actress was specially addressing herself with an implied meaning to the latter; and that he was aware that she was doing so. She felt no doubt that the motive for this was exactly that to which Ludovico had attributed it. It was important to the Diva to flatter and make a friend of so powerful a theatrical patron as the Marchese; and she took this very objectionable method, Paolina thought, of attaining that end. Paolina thought nothing more than this; but, nevertheless, it made her conceive a dislike for the Diva greater, perhaps, than the cause would seem to justify. The interval between the second and the third act Ludovico thought himself obliged to pass in the box of the Marchese Anna Lanfredi, in which Violante was sitting with her aunt. There, too, he found the ladies not quite disposed to be as frantically enthusiastic in their praises of the singer as the whole male part of the audience. The Marchesa Lanfredi thought that La Lalli was nothing at all in comparison with some singer who had charmed all Bologna some forty years before. And Violante, admitting that she had an exquisite voice and perfect method, confessed much as Paolina had done, that she did not quite like her, she hardly knew why. In the third act, the song sung by the sleep-walker in her state of unconsciousness--"Ah non credea mirarti,"--was a great success. And most fascinatingly lovely the Diva looked in her white night-dress, with her wreath of rich auburn tresses hanging in luxuriant curls around her shoulders. Shortly after this had been sung a liveried servant entered the Castelmare box, bearing a most superb bouquet of choice flowers, tied with a long streamer of broad rose-coloured ribbon, and deposited it on the front of the box. And then came the joyful finale "Ah non giunge." And in that the Diva seemed to surpass herself. It was a passionate carol of love, and joy, and triumph in which she seemed to pour the whole force and energy of her soul into the words and sounds that told the truth, the entirety, the perfection of her love, and the overwhelming happiness the recognition of it by its object gave her.
