Ayant de l'esprit comme quatre,
Dumas le fils a dit: "Voilà!
Ta femme il ne faut pas la battre,
Tue-la!"

...which I'd loosely translate:

Having the heart* of four
Dumas fils has said
You mustn't beat your wife
Kill her instead!

*or 'spirit', 'courage' etc. The phrase occurs in other 19th century writings, with a specific meaning that I can't be quite sure of without recourse to one of the big dictionaries.

The 'balloon' emerging from the chanter contains many words, but these are illegible even at high magnification. That's a pity, as I'd expect them to be lines quoted from Dumas and potentially informative.
