When settled in London, his first object was to renew an acquaintance with those whose friendship he had cultivated, and, as he considered, secured before he went to Italy. On calling, for this purpose, upon Mr. Coutts, that gentleman frankly said, he was not pleased with him for the quarrel which he had with Dr. Armstrong while on board ship. Fuseli attempted to remove the impression which had been made on Mr. Coutts' mind; but that gentleman replied, "I consider that the age and talents of the Doctor should have commanded a sufficient degree of respect from you, to have prevented any rudeness on your part; and I am very sorry to tell you, that he is now labouring under a severe, and what is considered an incurable malady." This account disarmed Fuseli, who had always entertained a high opinion of the talents of Armstrong, and considered his poems, particularly that on "The Art of preserving Health," productions of great merit. He therefore determined to suppress every hostile feeling, and to call upon the Doctor without delay. On sending up his name, he was admitted almost immediately into Armstrong's bed-chamber. The poet, however, could not restrain his naturally sarcastic humour, and the following dialogue took place:--Armstrong: "So, you have come back?" Fuseli: "Yes; I have come home." Armstrong: "Come, you mean, to London! 'the needy villain's gen'ral home;' however," (putting out his hand) "I thank you for this visit: you find me in bad plight; but I am glad to see you again." After this salutation they conversed amicably; but the Doctor did not long survive the interview.[12] About this time, the intimacy between Fuseli and Professor Bonnycastle commenced, which was kept up during their lives. The introduction took place at Mr. Johnson's house. Fuseli's voice being heard as he ascended the staircase, Mr. Johnson said to Bonnycastle, "I will now introduce you to a most ingenious foreigner, whom I think you will like; but, if you wish to enjoy his conversation, you will not attempt to stop the torrent of his words by contradicting him."
