He [Adam Smith] told me, that he never had been above once in his company; that the Doctor was a voluminous writer, and one of those authors who write from one end of the week to the other without interruption. A gentleman who happened to dine with Dr. Campbell in the house of a common acquaintance remarked, that he would be glad to possess a complete set of the Doctor's works. The hint was not lost; for next morning he was surprised at the appearance of a cart before his door. This cart was loaded with the books he had asked for; — the driver's bill amounted to seventy pounds! — As Dr. Campbell composed a part of the Universal History, and of the Biographia Britannica, we may suppose that these two ponderous Articles formed a great part of the cargo. The Doctor was in use to get a number of copies of his publications from the Printer, and keep them in his house for such an opportunity. A gentleman who came in one day exclaimed with surprise, "Have you ever read all these books?" — Nay," replied Dr. Campbell, laughing, "I have written them."
