In 1776 he married Miss Dorcas Turton, a friend of his first wife. It seems to have been her influence, to a large extent, that drew him away from Wesleyanism and religion. She was a woman of considerable education, and a great reader, kindly and affectionate in her disposition, a dutiful daughter to her aged and dependent father, whom she had supported after his failure in business by keeping a school. But she seems to have had no thought of religious truth as a basis for character and an impulse to right conduct, and her absolute indifference to religion soon told on the mind of a sensitive and impulsive man like Lackington. "I did not long remain in Mr. Wesley's Society," he writes, referring to this same year 1776, "and, what is remarkable, I well remember that, some years before, Mr. Wesley told his society in Broadmead, Bristol, in my hearing, that he could never keep a bookseller six months in his flock." Two years afterward Lackington entered into partnership for three years with Mr. Denis, an _honest man_, as he is emphatically styled, who brought a considerable sum of money into the business, by means of which the stock was at once doubled, and the sales vastly increased. Lackington now proposed the issue of a sale catalogue, to which his partner reluctantly consented. Both partners were employed in writing it, but the larger share fell to Lackington, whose name alone appeared on the title-page. It was issued in 1779, and the first week after its publication the partners took, what they regarded as the "large sum" of twenty pounds. Denis, finding his money pay better in business than in the Funds, invested a larger sum in stock, but when Lackington, who according to the terms of the agreement was sole purchaser, began to buy, as his partner thought, too largely, they had a dispute over the matter and dissolved partnership on friendly terms a year before the term of partnership had expired. Denis, to the end of his life, remained friendly with Lackington, and used to call in every day on passing his shop to inquire what purchases and sales he had effected, and now and then the _honest man_ lent his old partner money to help in paying bills.
