For a while the doctor sat looking at him. “Sir,” he said, at last, “tell me one thing. You are inflexible; you feel you have the right to be inflexible. But are you really so certain that it was not your duty, once upon a time, to save your daughter from the possibility of such misfortune?”

“What?” cried the other. “My duty? What do you mean?”

“I mean this, sir. When that marriage was being discussed, you certainly took precautions to inform yourself about the financial condition of your future son-in-law. You demanded that he should prove to you that his stocks and bonds were actual value, listed on the exchange. Also, you obtained some information about his character. In fact, you forgot only one point, the most important of all—that was, to inquire if he was in good health. You never did that.”

The father-in-law’s voice had become faint. “No,” he said.

“But why not?”

“Because that is not the custom.”

“Very well, but that ought to be the custom. Surely the father of a family, before he gives his daughter to a man, should take as much precaution as a business concern which accepts an employee.”

“You are right,” was the reply, “there should be a law.” The man spoke as a deputy, having authority in these matters.

But the doctor cried, “No, no, sir! Do not make a new law. We have too many already. There is no need of it. It would suffice that people should know a little better what syphilis is. The custom would establish itself very quickly for a suitor to add to all the other documents which he presents, a certificate of a doctor, as proof that he could be received into a family without bringing a pestilence with him. That would be very simple. Once let the custom be established, then the suitor would go to the doctor for a certificate of health, just as he goes to the priest for a certificate that he has confessed; and by that means you would prevent a great deal of suffering in the world. Or let me put it another way, sir. Nowadays, before you conclude a marriage, you get the lawyers of the two families together. It would be of at least equal importance to get their two doctors together. You see, sir, your inquiry concerning your son-in-law was far from complete. So your daughter may fairly ask you, why you, being a man, being a father who ought to know these things, did not take as much care of her health as you took of her fortune. So it is, sir, that I say to you, forgive!”

But Monsieur Loches said again, “Never!”
