An early nineteenth-century extended edition of a series of sermonising letters first published (in a far shorter form) in 1772. The letters are addressed to a young lady who, according to the introduction, 'was the daughter of one of the first families in London', and is described as a darling of society, but who ultimately feels empty, 'for whether at the toilet, the ball, the theatre, or the masquerade, Conscience could be heard - "Lovers of pleasure more than lovers of God"'.
