You must endeavour, if possible, to get me Mr. Warburton's Visitation Sermon at Lincoln, and the pamphlet against Dr. Webster. I want them exceedingly, to complete my collection of his smaller tracts. Dr. Chapman, you see, has published an answer to the Opinion, of which I shall scarce think it worth my while to take any notice. But would it not be proper to take the opportunity of advertising again the Opinion, that you may try to get off the remainder of the third edition. - I have considered your proposal about Horace, and cannot bate a farthing of what I mentioned in my last. We Authors, you know, have always some excuse to comfort ourselves for our books not selling. One reason at least for the Epistle to Augustus not going off was, I think, Thurlbourn's neglect to advertise it properly when it was published. I happened to be abroad at that time, and he is apt to be very careless. I have lately met with some of my own friends who never observed it in the papers till the other day, when it was advertised more carefully. You say, if you purchased the edition, you should expect to have the right of the copy absolute. I suppose you only mean the right of the copy of 750; that is, of this edition. Pray let me have your final answer as soon as possible. What I propose is to have the new edition printed off directly, so as to be finished at the farthest this summer; though I would not publish it till the edition of the Epistle to Augustus be sold off. And, as I am sensible, as you say, of the difference betwixt a piece of dry criticism and a novel, I should not insist on the payment of the 401. till a year after the time of publication, if that would make any difference. But, if I part with the copy for less than this sum, I think myself obliged in honour to let Mr. Thurlbourne have it, against whom I have no complaint, but that as he grows old he grows lazy. -I have not yet had leisure to look into the new edition of Montesquieu's Book, which is well spoken of here.
