may find you have been made a fool of before you know where you
are. But it is really true, all the same?

Dr. Stockmann. You can depend upon it that it is true. Won't you
sit down? (Settles him on the couch.) Isn't it a real bit of luck
for the town--

Morten Kiil (suppressing his laughter). A bit of luck for the
town?

Dr. Stockmann. Yes, that I made the discovery in good time.

Morten Kiil (as before). Yes, yes, Yes!--But I should never have
thought you the sort of man to pull your own brother's leg like
this!

Dr. Stockmann. Pull his leg!

Mrs. Stockmann. Really, father dear--

Morten Kiil (resting his hands and his chin on the handle of his
stick and winking slyly at the DOCTOR). Let me see, what was the
story? Some kind of beast that had got into the water-pipes,
wasn't it?

Dr. Stockmann. Infusoria--yes.

Morten Kiil. And a lot of these beasts had got in, according to
Petra--a tremendous lot.
