Up and down the City Road,
In and out the Eagle,
That's the way the money goes,
Pop goes the weasel.

This verse was subsequently modified (for nursery purposes) thus:

Half a pound of tuppenny rice,
Half a pound of treacle,
That's the way the money goes,[ 9 ]
Pop goes the weasel.

Many explanations have been given of ‘weasel.’ Some say it was a purse made of weasel skin; others that it was a tailor's flat-iron which used to be pawned (or ‘popped’) to procure the needful for admission to the tavern. A third (and more intelligible) suggestion is that the line is simply a catch phrase, without any meaning.

There is a notable reference to the organ in Little Dorrit. Arthur Clennam goes to call on old Frederick Dorrit, the clarionet player, and is directed to the house where he lived. ‘There were so many lodgers in this house that the door-post seemed to be as full of bell handles as a cathedral organ is of stops,’ and Clennam hesitates for a time, ‘doubtful which might be the clarionet stop.’

Further on in the same novel we are told that it was the organ that Mrs. Finching was desirous of learning.

I have said ever since I began to recover the blow of Mr. F's death that I would learn the organ of which I am extremely fond but of which I am ashamed to say I do not yet know a note.

The following fine description of the tones of an organ occurs in The Chimes:

The organ sounded faintly in the church below. Swelling by degrees the melody ascended to the roof, and filled the choir and nave. Expanding more and more, it rose up, up; up, up; higher, higher, higher up; awakening agitated hearts within the burly piles of oak, the hollow bells, the iron-bound doors, the stairs of solid stone; until the tower walls were insufficient to contain it, and it soared into the sky.

The effect of this on Trotty Veck was very different from that which another organ had on the benevolent old lady we read of in Our Parish. She subscribed £20 towards a new instrument for the parish church, and was so overcome when she first heard it that she had to be carried out by the pew-opener.
