Mary Moser was the only daughter of George Michael Moser, R.A., goldchaser and enameller, and the first Keeper of the Royal Academy of Arts in London. His daughter was a very distinguished flower-painter, and was the only lady besides Angelica Kauffman who was ever elected an Academician: she became afterwards Mrs. Lloyd. Miss Moser, says Smith, in his _Life of Nollekens_, was somewhat precise, but was at times a most cheerful companion: he has printed three of her letters, two to Mrs. Lloyd, the wife of the gentleman to whom she herself was afterwards married; and the other to Fuseli, while in Rome, of whom she was said to have been an admirer. In one to the former, alluding to the absurd fashions of the beginning of the reign of George the Third, she says:--"Come to London and admire our plumes; we sweep the skies! a duchess wears six feathers, a lady four, and every milkmaid one at each corner of her cap. Fashion is grown a monster: pray tell your operator that your hair must measure three-quarters of a yard from the extremity of one wing to the other." The second letter is chiefly on Lord Chesterfield's Advice to his Son: she says to her friend, "If you have read Lord Chesterfield's Letters, give me your opinion of them, and what you think of his Lordship: for my part, I admire wit and adore good manners, but at the same time I should detest Lord Chesterfield, were he alive, young, and handsome, and my lover, if I supposed, as I do now, his wit was the result of thought, and that he had been practising the graces in the looking-glass." In her letter to Fuseli, she gives this account of the Exhibition of the Royal Academy in the year 1770:--"Reynolds was like himself in pictures which you have seen; Gainsborough beyond himself in a portrait of a gentleman in a Vandyck habit; and Zoffany superior to everybody in a portrait of Garrick in the character of Abel Drugger, with two figures, Subtle and Face. Sir Joshua agreed to give a hundred guineas for the picture; Lord Carlisle had an hour after offered Reynolds twenty to part with it, which the Knight generously refused, resigned his intended purchase to the Lord, and the emolument to his brother artist. He is a gentleman! Angelica made a very great addition to the show, and Mr. Hamilton's picture of Briseis parting from Achilles was very much admired; the Briseis in taste, _à l'antique_, elegant and simple. Cotes, Dance, Wilson, &c., as usual."
