Chasles

The leap suggested by M. Chasles is exorbitant; such a headlong development would be unintelligible.

But since a French critic, M. Philarète Chasles, has made the same accusation, we must pause and consider it.

In those days there was a famous mathematician whose name was Chasles.

At last other learned men, who did not love Chasles, tried to make him understand that he had been befooled.
