The second book of the Minstrel appeared in 1774. In 1776 he was prevailed on to publish, by subscription, in a more splendid form, his Essay on Truth, which was now accompanied by two other essays, on Poetry and Music, and on Laughter and Ludicrous Composition; and by Remarks on the Utility of Classical Learning. This was succeeded in 1783, by dissertations moral and critical, on Memory and Imagination, on Dreaming, on the Theory of Language, on Fable and Romance, on the Attachments of Kindred, and on Illustrations of Sublimity; being, as he states in the preface, "part of a course of prelections read to those young gentlemen whom it was his business to initiate in the elements of moral science." In 1786, he published a small treatise, entitled Evidences of the Christian Religion, at the suggestion of Porteus, who was now a bishop; and in 1790 and 1793 two volumes of Elements of Moral Science, containing an abridgment of his public lectures on moral philosophy and logic. His only remaining publication was an edition of the juvenile works of the elder of his two sons, who was taken off by a consumption (November 1790), at the age of twenty-two. To the education of this boy he had attended with such care and discernment as the anxiety of a parent only could dictate, and had watched his unfolding excellence with fondness such as none but a parent could feel. At the risque of telling my reader what he may, perhaps, well remember, I cannot but relate the method which he had taken to impress on his mind, when a child, the sense of his dependence on a Supreme Being; of which Porteus well observed, that it had all the imagination of Rousseau, without his folly and extravagance.
