The present sermon, by John Newton, was preached on the death of his dear friend, Richard Conyers. Conyers [1725-1786], though already ordained, experienced an evangelical conversion in 1756. He lost his ministerial charge and became an itinerant under Selina Countess of Huntingdon. 

He was friends with George Whitefield and began travelling with him as a co-evangelist in 1768. He was also close with William Cowper, John Newton, Thomas Haweis, and others, printing the first hymnal to include hymns by Newton, and the predecessor to Newton's Olney Hymnal.

Not surprisingly, the rear sheet is an advertisement catalogue for the various works of Newton, including his Hymnal, Cardiphonia, his Sermons on Handel's Messiah, etc.
