"Edinburgh, 1 Jan. 1759.
"Dear Sir,—If I had not considered a letter of mere compliment as an impertinent interruption to one who is so busy as you commonly are, I would long before this have made my acknowledgments to you for the civilities which you was so good as to show me while I was in London. I had not only a proof of your obliging disposition, but I reaped the good effects of it.
"The papers to which I got access by your means, especially those from Lord Royston, have rendered my work more perfect than it could have otherwise been. My history is now ready for publication, and I have desired Mr. Millar to send you a large paper copy of it in my name, which I beg you may accept as a testimony of my regard and of my gratitude. He will likewise transmit to you another copy, which I must entreat you to present to my Lord Royston, with such acknowledgments of his favours toward me as are proper for me to make. I have printed a short appendix of original papers. You will observe that there are several inaccuracies in the press work. Mr. Millar grew impatient to have the book published, so that it was impossible to send down the proofs to me. I hope, however, the papers will be abundantly intelligible. I published them only to confirm my own system, about particular facts, not to obtain the character of an antiquarian. If, upon perusing the book, you discover any inaccuracies, either with regard to style or facts, whether of great or of small importance, I will esteem it a very great favour if you'll be so good as to communicate them to me. I shall likewise be indebted to you, if you'll let me know what reception the book meets with among the literati of your acquaintance. I hope you will be particularly pleased with the critical dissertation at the end, which is the production of a co-partnership between me and your friend Mr. Davidson. Both Sir D. Dalrymple and he offer compliments to you. If Dean Tucker be in town this winter, I beg you will offer my compliments to him.
"I am, w. great regard, Dr. Sir,

TO DR. BIRCH.
"Edinburgh, 13 Dec. 1759.
"Dear Sir,—I beg leave once more to have recourse to your good nature and to your love of literature, and to presume upon putting you to a piece of trouble. After considering several subjects for another history, I have at last fixed upon the reign of Charles V., which contains the first establishment of the present political system of Europe. I have begun to labour seriously upon my task. One of the first things requisite was to form a catalogue of books which must be consulted. As I never had access to very copious libraries, I do not pretend to any extensive knowledge of authors, but I have made a list of such as I thought most essential to the subject, and have put them down just in the order which they occurred to me, or as I found them mentioned in any book I happened to read. I beg you would be so good as to look it over, and as your erudition and knowledge of books is infinitely superior to mine, I doubt not but you'll be able to make such additions to my catalogue as may be of great use to me. I know very well, and to my sorrow, how servilely historians copy from one another, and how little is to be learned from reading many books, but at the same time when one writes upon any particular period, it is both necessary and decent for him to consult every book relating to it, upon which he can lay his hands. I am sufficiently master of French and Italian; but have no knowledge of the Spanish or German tongues. I flatter myself that I shall not suffer much by this, as the two former languages, together with the Latin, will supply me with books in abundance. Mr. Walpole informed me some time ago, that in the catalogue of Harleian MSS. in the British Museum, there is a volume of papers relating to Charles V., it is No. 295. I do not expect much from it, but it would be extremely obliging if you would take the trouble of looking into it and of informing me in general what it contains. In the catalogue I have inclosed, this mark × is prefixed to all the books which I can get in this country; if you yourself, or any friend with whom you can use freedom, have any of the other books in my list, and will be so good as to send them to Mr. Millar, he will forward them to me, and I shall receive them with great gratitude and return them with much punctuality. I beg leave to offer compliments to all our common friends, and particularly to Dean Tucker, if he be in town this season. I wish it were in my power to confer any return for all the trouble you have taken in my behalf—"
