publication, so it was only privately printed.

Amiable and accommodating at first, and neither ill-educated nor stupid,
Harriet did not improve in tone as she advanced in womanhood. Her
sympathy or tolerance for her husband's ideals and vagaries flagged;
when they differed she gave him the cold shoulder; she wanted
luxuries--such as a carriage of her own--which he neither cared for nor
could properly afford. He even said--and one can hardly accuse him of
saying it insincerely--that she had been unfaithful to him: this however
remains quite unproved, and may have been a delusion. He sought the
society of the philosopher Godwin, then settled as a bookseller in
Skinner Street, Holborn. Godwin's household at this time consisted of
his second wife, who had been a Mrs. Clairmont; Mary, his daughter by
his first wife, the celebrated Mary Wollstonecraft; and his young son by
his second wife, William; also his step-children, Charles and Clare
Clairmont, and Fanny Wollstonecraft (or Imlay), the daughter of Mary
Wollstonecraft by her first irregular union with Gilbert Imlay. Until
May 1814, when she was getting on towards the age of seventeen, Shelley
had scarcely set eyes on Mary Godwin: he then saw her, and a sudden
passion sprang up between them--uncontrollable, or, at any rate,
uncontrolled. Harriet Shelley has left it on record that the advances
and importunities came from Mary Godwin to Shelley, and were for a while
resisted: it was natural for Harriet to allege this, but I should not
suppose it to be true, unless in a very partial sense. Shelley sent for
his wife, who had gone for a while to Bath (perhaps in a fit of
pettishness, but this is not clear), and explained to her in June that
they must separate--a resolve which she combated as far as seemed
possible, but finally she returned to Bath, staying there with her
father and sister. Shelley made some arrangements for her convenience,
and on the 28th of July he once more eloped, this time with Mary Godwin.
