When the Rev. Mr. Cowper [one of the ministers of Perth] was made Bishop of Galloway, an old woman, who had been one of his parishioners at Perth, and a favourite, could not be persuaded that her minister had deserted the Presbyterian cause, and resolved to satisfy herself. She paid him a visit in the Canongate, where he had his residence, as Dean of the Chapel Royal. The retinue of servants through which she passed staggered the good woman’s confidence; and, on being ushered into the room where the bishop sat in state, she exclaimed, ‘Oh Sir! what’s this? and hae ye really left the guid cause, and turned prelate? ‘Janet,’ said the bishop, ‘I have got new light upon these things.’ ‘So I see, Sir,’ replied Janet, ‘for whan ye was at Perth, ye had but ae candle, an’ now ye’ve got twa before ye — that’s a’ your new light.’
