“Mrs. Thrale, of the whole coterie, was alone at her ease.  She feared not Dr. Johnson; for fear made no part of her composition; and with Mrs. Greville, as a fair rival genius, she would have been glad, from curiosity, to have had the honour of a little tilt, in full carelessness of its event; for though triumphant when victorious, she had spirits so volatile, and such utter exemption from envy or spleen, that she was gaily free from mortification when vanquished.  But she knew the meeting to have been fabricated for Dr. Johnson; and, therefore, though not without difficulty, constrained herself to be passive.

“When, however, she observed the sardonic disposition of Mr. Greville to stare around him at the whole company in curious silence, she felt a defiance against his aristocracy beat in every pulse; for, however grandly he might look back to the long ancestry of the Brookes and the Grevilles, she had a glowing consciousness that her own blood, rapid and fluent, flowed in her veins from Adam of Saltsberg; and, at length, provoked by the dullness of a taciturnity that, in the midst of such renowned interlocutors, produced as narcotic a torpor as could have been caused by a dearth the most barren of human faculties; she grew tired of the music, and yet more tired of remaining, what as little suited her inclinations as her abilities, a mere cipher in the company; and, holding such a position, and all its concomitants, to be ridiculous, her spirits rose rebelliously above her control; and, in a fit of utter recklessness of what might be thought of her by her fine new acquaintance, she suddenly, but softly, arose, and stealing on tip-toe behind Signor Piozzi, who was accompanying himself on the piano-forte to an animated arria parlante, with his back to the company, and his face to the wall; she ludicrously began imitating him by squaring her elbows, elevating them with ecstatic shrugs of the shoulders, and casting up her eyes, while languishingly reclining her head; as if she were not less enthusiastically, though somewhat more suddenly, struck with the transports of harmony than himself.

“This grotesque ebullition of ungovernable gaiety was not perceived by Dr. Johnson, who faced the fire, with his back to the performer and the instrument.  But the amusement which such an unlooked for exhibition caused to the party, was momentary; for Dr. Burney, shocked lest the poor Signor should observe, and be hurt by this mimicry, glided gently round to Mrs. Thrale, and, with something between pleasantness and severity, whispered to her, ’Because, Madam, you have no ear yourself for music, will you destroy the attention of all who, in that one point, are otherwise gifted?’

“It was now that shone the brightest attribute of Mrs. Thrale, sweetness of temper.  She took this rebuke with a candour, and a sense of its justice the most amiable:  she nodded her approbation of the admonition; and, returning to her chair, quietly sat down, as she afterwards said, like a pretty little miss, for the remainder of one of the most humdrum evenings that she had ever passed.
