The cause of Fuseli's return to the capital was, that, at this time, some of the literati of Germany and Switzerland had it in contemplation to establish a regular channel of literary communication between those countries and England. Fuseli's tutors and friends, Bodmer, Breitenger, and Sulzer, felt a lively interest in this project, and took an active part in carrying the design into execution. These philosophers thought, that there was no person better qualified than Fuseli to conduct the business. He was possessed of great mental and bodily activity; they had the highest opinion of his talents; and they considered that his extensive knowledge of modern languages would facilitate their project. In making the proposal, Sulzer represented that it would be inconvenient, if not dangerous, for him to go back, within a limited time, to Zurich; for it was well known to the family of Grebel, that he had taken the most active part in the affair against their relation: and moreover that, although his companions might, under this circumstance, from their powerful connexions, return at no distant period with impunity, yet Fuseli, not so happily situated, would suffer from all the effects of tyranny which power could exercise. This reasoning had its due effect upon the mind of Fuseli; he however asked the opinion of his father, which being in favour of his accepting the offer of Sulzer, made him determine to visit England. Sir Andrew Mitchell was at this time the British minister at the court of Prussia: he was a friend of Sulzer's, who accordingly introduced Fuseli to him. At his house he improved much in English conversation, and he met several men of literary note, among whom was Dr. Armstrong, who was then physician to the British forces in Germany; and with this gentleman he became intimately acquainted. Sir Andrew Mitchell was about to return to England; and being pleased with the society of Fuseli, and wishing to give every facility to the views of Sulzer, he liberally made the offer to the latter that his young friend should accompany him to London, and promised that he would give him his protection when there, and such introductions as should be useful in effecting the object of his mission. This offer was not to be refused: Fuseli, therefore, set out with Sir Andrew, and arrived in England at the close of the year 1763. Before he quitted Prussia, he took leave of Lavater, his early and devoted friend, who, at parting, put into his hands a paper, which he previously had framed and glazed, on which was written, in German, "Thue den siebenden theil von dem was du thun kannst."[8] "Hang this in your bed-chamber, my dear friend," said he; "look at it occasionally, and I foresee the result."
