I am at a loss how to describe the success of the work, without betraying the vanity of the writer. The first impression was exhausted in a few days; a second and third edition were scarcely adequate to the demand; and the bookseller's property was twice invaded by the pirates of Dublin. My book was on every table, and almost on every toilette; the historian was crowned by the taste or fashion of the day; nor was the general voice disturbed by the barking of any profane critic. The favour of mankind is most freely bestowed on a new acquaintance of any original merit; and the mutual surprise of the public and their favourite is productive of those warm sensibilities, which at a second meeting can no longer be rekindled. If I listened to the music of praise, I was more seriously satisfied with the approbation of my judges. The candour of Dr. Robertson embraced his disciple. A letter from Mr. Hume overpaid the labour of ten years, but I have never presumed to accept a place in the triumvirate of British historians. That curious and original letter will amuse the reader, and his gratitude should shield my free communication from the reproach of vanity. "DEAR SIR, EDINBURGH, 18th March 1776. "As I ran through your volume of history with great avidity and impatience, I cannot forbear discovering somewhat of the same impatience in returning you thanks for your agreeable present, and expressing the satisfaction which the performance has given me. Whether I consider the dignity of your style, the depth of your matter, or the extensiveness of your learning, I must regard the work as equally the object of esteem; and I own that if I had not previously had the happiness of your personal acquaintance, such a performance from an Englishman in our age would have given me some surprise. You may smile at this sentiment; but as it seems to me that your countrymen, for almost a whole generation, have given themselves up to barbarous and absurd faction, and have totally neglected all polite letters, I no longer expected any valuable production ever to come from them. I know it will give you pleasure (as it did me) to find that all the men of letters in this place concur in the admiration of your work, and in their anxious desire of your continuing it.
