Next to old 'Kit North,' the most truly beloved contributor to Blackwood was 'Delta,' whose poetry was for years expected, almost of course, in every number. As Wilson's identity was well-nigh lost in his imaginary character, so plain Dr. Moir was, in the literary world, merged in 'Delta' of Blackwood. But to the inhabitants of Musselburg he sustained a character altogether different, and the gentle _Delta_ was only known as one worthy of the title of 'the good physician.' I lived at Musselburg two years, and had ample opportunities of personal acquaintance. Dr. Moir was a man of highly benevolent countenance, and of quiet and retiring manners. His practice was very extensive, and at almost all hours he could have been seen driving an old gray horse through the streets and suburbs of the town. The ancient character of Musselburg seemed to have been as congenial to his temperament as Nuremberg was to that of Hans Sachs. Indeed, in antiquity it can glory over 'Auld Reekie,' according to the quaint couplet,-- 'Musselboro' was a boro' when Edinburgh was nane; Musselboro'll be a boro' when Edinburgh is gane.' Moir was buried at Inveresk, where his remains are honored by a noble monument; the memory of his genius will be cherished by all readers of Blackwood. He died in 1854. While engaged on the Encyclopedia to which we have made reference, I made the acquaintance of McCulloch, the distinguished writer of finances, who furnished the article on 'Banking.' However distinguished may have been the position of this man in point of talent, he failed utterly to command respect; and I chiefly remember his coarse, overbearing tone of boastful superiority, and his abusive language to the compositors who set up his MSS. That they found the latter difficult of deciphering is not surprising, since the sheet looked less like human calligraphy than a row of bayonets. McCulloch had edited the '_Scotsman_' with decided ability, and having attracted the attention of Lord Brougham, had received an appointment in the stationer's office. But in his promotion he quickly forgot his humble origin, and displayed his native vulgarity by lording it over the craftsmen who gave form and life to his thoughts.
