Accompanied by Mr Eyan, Mr Wesley set out for Londonderry, where they arrived on May 11th, Mr Johnson having got there three days previously, to take the place of Mr Clough. Wesley was entertained by societies Knox, who on the following Sunday took him to the cathedral, and led him to the Corporation-pew, where he, next the Mayor,
Mr William Kennedy. , resulted in an invitation from the latter to dinner, which was accepted. Mr Wesley remained for more than a fortnight in the city and preached in the Linen Hall. On one occasion ''nearly all the inhabitants of the city were present," and so general an impression upon a congregation he had hardly ever seen.
