ADOLPH. [Wildly] There can be no sum without an addition. You get an endless decimal fraction for quotient when your division does not work out evenly. I have not added anything.
TEKLA. But I can do the adding myself.
ADOLPH. I believe it, but then I am not doing it.
TEKLA. No, but that's what you wanted to do.
ADOLPH. [Exhausted, closing his eyes] No, no, no—don't speak to me—you'll drive me into convulsions. Keep silent! Leave me alone! You mutilate my brain with your clumsy pincers—you put your claws into my thoughts and tear them to pieces!
(He seems almost unconscious and sits staring straight ahead while his thumbs are bent inward against the palms of his hands.)
TEKLA. [Tenderly] What is it? Are you sick?
(ADOLPH motions her away.)
TEKLA. Adolph!
(ADOLPH shakes his head at her.)
