Mrs Varden was a lady of what is commonly called an uncertain temper--a phrase which being interpreted signifies a temper tolerably certain to make everybody more or less uncomfortable.

Thus it generally happened, that when other people were merry, Mrs Varden was dull; and that when other people were dull, Mrs Varden was disposed to be amazingly cheerful.

Indeed the worthy housewife was of such a capricious nature, that she not only attained a higher pitch of genius than Macbeth, in respect of her ability to be wise, amazed, temperate and furious, loyal and neutral in an instant, but would sometimes ring the changes backwards and forwards on all possible moods and flights in one short quarter of an hour; performing, as it were, a kind of triple bob major on the peal of instruments in the female belfry, with a skilfulness and rapidity of execution that astonished all who heard her.
It had been observed in this good lady (who did not want for personal attractions, being plump and buxom to look at, though like her fair daughter, somewhat short in stature) that this uncertainty of disposition strengthened and increased with her temporal prosperity; and divers wise men and matrons, on friendly terms with the locksmith and his family, even went so far as to assert, that a tumble down some half-dozen rounds in the world's ladder--such as the breaking of the bank in which her husband kept his money, or some little fall of that kind--would be the making of her, and could hardly fail to render her one of the most agreeable companions in existence.

Whether they were right or wrong in this conjecture, certain it is that minds, like bodies, will often fall into a pimpled ill-conditioned state from mere excess of comfort, and like them, are often successfully cured by remedies in themselves very nauseous and unpalatable.
Mrs Varden's chief aider and abettor, and at the same time her principal victim and object of wrath, was her single domestic servant, one Miss Miggs; or as she was called, in conformity with those prejudices of society which lop and top from poor hand-maidens all such genteel excrescences--Miggs.

This Miggs was a tall young lady, very much addicted to pattens in private life; slender and shrewish, of a rather uncomfortable figure, and though not absolutely ill-looking, of a sharp and acid visage.
