Our first misfortune, of the kind from which we soon suffered even more severely, happened here. Our little girl, an infant in whose small features I fancied that I traced great resemblance to her father, showed symptoms of suffering from the heat of the climate. Teething increased her illness and danger. We were at Este, and when we became alarmed, hastened to Venice for the best advice. When we arrived at Fusina, we found that we had forgotten our passport, and the soldiers on duty attempted to prevent our crossing the laguna; but they could not resist Shelley's impetuosity at such a moment. We had scarcely arrived at Venice before life fled from the little sufferer, and we returned to Este to weep her loss. After a few weeks spent in this retreat, which was interspersed by visits to Venice, we proceeded southward. NOTE ON "PROMETHEUS UNBOUND", BY MRS. SHELLEY. On the 12th of March, 1818, Shelley quitted England, never to return. His principal motive was the hope that his health would be improved by a milder climate; he suffered very much during the winter previous to his emigration, and this decided his vacillating purpose. In December, 1817, he had written from Marlow to a friend, saying: 'My health has been materially worse. My feelings at intervals are of a deadly and torpid kind, or awakened to such a state of unnatural and keen excitement that, only to instance the organ of sight, I find the very blades of grass and the boughs of distant trees present themselves to me with microscopic distinctness. Towards evening I sink into a state of lethargy and inanimation, and often remain for hours on the sofa between sleep and waking, a prey to the most painful irritability of thought. Such, with little intermission, is my condition. The hours devoted to study are selected with vigilant caution from among these periods of endurance. It is not for this that I think of travelling to Italy, even if I knew that Italy would relieve me. But I have experienced a decisive pulmonary attack; and although at present it has passed away without any considerable vestige of its existence, yet this symptom sufficiently shows the true nature of my disease to be consumptive. It is to my advantage that this malady is in its nature slow, and, if one is sufficiently alive to its advances, is susceptible of cure from a warm climate. In the event of its assuming any decided shape, IT WOULD BE MY DUTY to go to Italy without delay. It is not mere health, but life, that I should seek, and that not for my own sake--I feel I am capable of trampling on all such weakness; but for the sake of those to whom my life may be a source of happiness, utility, security, and honour, and to some of whom my death might be all that is the reverse.'
