Having been called to a town on the borders of Yorkshire to a medical consultation, he chanced to be taking a glass of wine with the landlord of the inn at which he stopped, when the waiter brought in a note to be changed, saying 'that the Quaker gentleman who had been for some days in the house, and was about to depart, had sent it to be changed, in order that he might pay his bill.' The landlord took the note, and looked at it.

'A fifty-pound bill,' said he; 'I don't like changing bills of that amount, lest they should prove bad ones; however, as it comes from a Quaker gentleman, I suppose it is all right.' The mention of a fifty-pound note aroused the attention of my friend, and he requested to be permitted to look at it; he had scarcely seen it, when he was convinced that it was one of the same description as those which had brought me into trouble, as it corresponded with them in two particular features, which the agent of the bank had pointed out to him and others as evidence of their spuriousness.

My friend, without a moment's hesitation, informed the landlord that the note was a bad one, expressing at the time a great wish to see the Quaker gentleman who wanted to have it changed.

'That you can easily do,' said the landlord, and forthwith conducted him into the common room, where he saw a respectable-looking man, dressed like a Quaker, and seemingly about sixty years of age.
"My friend, after a short apology, showed him the note which he held in his hand, stating that he had no doubt it was a spurious one, and begged to be informed where he had taken it, adding, that a particular friend of his was at present in trouble, owing to his having taken similar notes from a stranger at Horncastle; but that he hoped that he, the Quaker, could give information by means of which the guilty party or parties, could be arrested.

At the mention of Horncastle, it appeared to my friend that the Quaker gave a slight start.
