“Who told you that, Porthos?”

“The doctor. A sort of dome which would bear Notre-Dame.”

“Bah!”

“Yes, it seems that our skulls are made in that manner.”

“Speak for yourself, my dear fellow, it is your own skull that is made in that manner, and not the skulls of other people.”

“Well, that may be so,” said Porthos, conceitedly, “so much, however, was that the case, in my instance, that no sooner did the luster fall upon the dome which we have at the top of our head, than there was a report like a cannon, the crystal was broken to pieces, and I fell, covered from head to foot.”
