"In the first place you are not fit to mix with those poor creatures, in yonder; their oaths would curdle your blood; and in the second, you are not strong, and would be sure to take the disease at once."

"I am perfectly well; my lungs are now as healthy as yours, and I am not afraid of diphtheria. You detailed nurses, who refused to serve; I volunteer; have you any right to reject me?"

"Yes, the right to protect and save your life, which is worth twenty of those already in danger," replied Mr. Singleton, pausing in his task of filling capsules with quinine.

"Who made you a judge of the value of souls? My life belongs first to God, who gave it, next to myself; and if I choose to jeopardize it, in work among my suffering comrades in disgrace, you must not usurp the authority to prevent me."

"I think I may safely say, no such selfish motive underlies my resolution.

"To keep you here is about as sacrilegious as it would have been to thrust St. Catherine among the chain-gang in the galleys," muttered the doctor.

"No doubt duty called her to much worse places; therefore, when she died, the angels buried her on Sinai," answered the prisoner; before whose wistful eyes drifted the memory of Luini's picture.
