Professor Liedenbrock seemed to be greatly abstracted.
The ruling thought gave him no rest.

Evidently he had gone deeply into the matter, analytically and with profound scrutiny.

He had brought all the resources of his mind to bear upon it during his walk, and he had come back to apply some new combination.
He sat in his armchair, and pen in hand he began what looked very much like algebraic formula: I followed with my eyes his trembling hands, I took count of every movement.

For three long hours my uncle worked on without a word, without lifting his head; rubbing out, beginning again, then rubbing out again, and so on a hundred times.
I knew very well that if he succeeded in setting down these letters in every possible relative position, the sentence would come out.

But I knew also that twenty letters alone could form two quintillions, four hundred and thirty-two quadrillions, nine hundred and two trillions, eight billions, a hundred and seventy-six millions, six hundred and forty thousand combinations.
