Mr Blount: A good day's work, Bolton! You're getting faster all the time. Beats me how you do it!
Dr. Bolton: [Bitterly] No matter how fast I still can't save them!
Mr Blount: Yes, most distresing, but, alas, inevitably you can't have operations without screams. Pain and the knife, they're inseparable!
Dr. Bolton: I beg to differ. Someday surgery must and will be made painless.

Dr. Bolton: [In the Seven Dials] This place must breed a hundres fevers!

Hospital chairman: Mr. Bolton, the committee have decided against holding ant further demonstrations
Dr. Bolton: Well, Charles, you've lost faith with me too?
Hospital chairman: The decision's for your own good.
Dr. Bolton: You can't stop me. Operations without pain are possible, and I'll not rest until I've proved it to you!
