"But a'n't there something wrong about it, doctor?"

"No, I presume not. I make my charges carefully, and draw off my bills in exact accordance with them."

"But there must be, doctor. How in the world could you make a bill of one hundred and fifty dollars against me? I've had no serious sickness in my family."

"And yet, Mr. Marvel, I have been called in almost every week, and sometimes three or four times in as many days."

"Impossible!"

"I'll show you my ledger, if that will satisfy you, where every visit is entered."
