"You had a bump on your head I suppose?" interrupted D'Artagnan.

"I had five."

"Why five?"

"I will tell you; the luster had, at its lower extremity, five gilt
ornaments; excessively sharp."

"Oh!"

"Well, these five ornaments penetrated my hair, which, as you see, I wear
very thick."

"Fortunately so."

"And they made a mark on my skin. But just notice the singularity of it,
these things seem really only to happen to me! Instead of making
indentations, they made bumps. The doctor could never succeed in
explaining that to me satisfactorily."

"Well, then, I will explain it to you."

"You will do me a great service if you will," said Porthos, winking his
eyes, which, with him, was sign of the profoundest attention.

"Since you have been employing your brain in studies of an exalted
character, in important calculations, and so on, the head has gained a
certain advantage, so that your head is now too full of science."
