I now made arrangements for my journey; but one feeling haunted me, which filled me with fear and agitation. During my absence I should leave my friends unconscious of the existence of their enemy, and unprotected from his attacks, exasperated as he might be by my departure. But he had promised to follow me wherever I might go; and would he not accompany me to England? This imagination was dreadful in itself, but soothing, inasmuch as it supposed the safety of my friends. I was agonized with the idea of the possibility that the reverse of this might happen. But through the whole period during which I was the slave of my creature, I allowed myself to be governed by the impulses of the moment; and my present sensations strongly intimated that the fiend would follow me, and exempt my family from the danger of his machinations.
It was in the latter end of August that I departed, to pass two years of exile. Elizabeth approved of the reasons of my departure, and only regretted that she had not the same opportunities of enlarging her experience, and cultivating her understanding. She wept, however, as she bade me farewell, and entreated me to return happy and tranquil. “We all,” said she, “depend upon you; and if you are miserable, what must be our feelings?”
I threw myself into the carriage that was to convey me away, hardly knowing whither I was going, and careless of what was passing around. I remembered only, and it was with a bitter anguish that I reflected on it, to order that my chemical instruments should be packed to go with me: for I resolved to fulfil my promise while abroad, and return, if possible, a free man. Filled with dreary imaginations, I passed through many beautiful and majestic scenes; but my eyes were fixed and unobserving. I could only think of the bourne of my travels, and the work which was to occupy me whilst they endured.
