 We pined and starved. Some of us managed to stay alive for years, I guess. Edgar grew up to be a handsome young man, had a girl, too. He was careless about his meals. He didn't eat right. Stayed out late at night when he ought to have been in bed. All that put a strain on his body. Something happened. We turned so our chance to escape. Edgar paid me a cloth and lost weight. We multiplied so fast, Edgar's cells couldn't keep up with us. So we spread and spread and staked out new blocks. His girl was... I remember Edgar in the sanatorium. Yeah, but that's where I got you, by the way. Every patient has his own paper cup. How is it you weren't destroyed, too? Sent some of Edgar's sputum to the laboratory to be examined. He kept us in an incubator when it was warm, and there we grew. Well, I guess that's the story. And it was the man in the white coat who gave this culture to me. Do you know if Edgar got... He recovered completely. He's happily married and has a boy of his own now. Things have changed, he be. Edgar Sr. had learned his lesson, so he took young Edgar to the doctor and had it to burk him and test made. Just this simple skin test, tells if there are any germs like you present in a person's body. Can't see his hidden away, so they invent this clever test. This test was negative. No germs in young Edgar's body. Suppose it had been positive, Professor. In that case, the doctor would have had an X-ray picture made of his chest, as he did with another of his patients, Mary, a sweet young girl from high school. Her test came back positive, and the doctor had this X-ray picture made of her chest. Please, see a tube. There, you see the ribs. Here is the healthy lung tissue. And there, see that spot? It's a little tubercle, like the one in Edgar Sr.'s lung. It's hard and firm now. No germ will ever get out of that tubercle. And once every year until she's grown up, the doctor will make another X-ray picture. But Professor, what's to become of all my tribe, with that kind of thing going on? Sorry, old camera, but you're almost through. When all young folks get a tuberculin test, and those who react positively get an X-ray, TB germs are going to die out. This is a fight to the finish, and man is going to win this fight. Bye, Mr. Germ. I see the day when tuberculosis will be late. I see happy, healthy children growing up without the fear that their lives will be ruined by it. I can see parents happy with grown-up children, parents who in the old days would have died an early death. I can really see this ancient misery disappearing. How about a cookie and a cool drink? Thank you, Jim. He has just told us enough...
