“I discovered that he was a member of my own profession—a mulatto from the Southern States of America, by birth. The one fatal event of his life had been his marriage. Every worst offence of which a bad woman can be guilty, his vile wife had committed—and his infatuated love clung to her through it all. She had disgraced and ruined him. Not once, but again and again he had forgiven her, under circumstances which degraded him in his own estimation, and in the estimation of his best friends. On the last occasion when she left him, he had followed her to Montreal. In a fit of drunken frenzy, she had freed him from her at last by self-destruction. Her death affected his reason. When he was discharged from the asylum, he spent his last miserable savings in placing a monument over her grave. As long as his strength held out, he made daily pilgrimages to the cemetery. And now, when the shadow of death was darkening over him, his one motive for clinging to life, his one reason for vainly entreating me to cure him, still centred in devotion to the memory of his wife. ‘Nobody will take care of her grave,’ he said, ‘when I am gone.’

“My love, I have always thought fondly of you. After hearing this miserable story, my heart overflowed with gratitude to God for giving me Carmina.

“He died yesterday. His last words implored me to have him buried in the same grave with the woman who had dishonoured him. Who am I that I should judge him? Besides, I shall fulfil his last wishes as a thank-offering for You.

“There is still something more to tell.

“On the day before his death he asked me to open an old portmanteau—literally, the one thing that he possessed. He had no money left, and no clothes. In a corner of the portmanteau there was a roll of papers, tied with a piece of string—and that was all.

“I can make you but one return,’ he said; ‘I give you my book.’

“He was too weak to tell me what the book was about, or to express any wish relative to its publication. I am ashamed to say I set no sort of value on the manuscript presented to me—except as a memorial of a sad incident in my life. Waking earlier than usual this morning, I opened and examined my gift for the first time.

“To my amazement, I found myself rewarded a hundredfold for the little that I had been able to do. This unhappy man must have been possessed of abilities which (under favouring circumstances) would, I don’t hesitate to say, have ranked him among the greatest physicians of our time. The language in which he writes is obscure, and sometimes grammatically incorrect. But he, and he alone, has solved a problem in the treatment of disease, which has thus far been the despair of medical men throughout the whole civilised world.

“If a stranger was looking over my shoulder, he would be inclined to say, This curious lover writes to his young lady as if she was a medical colleague! We understand each other, Carmina, don’t we? My future career is an object of interest to my future wife. This poor fellow’s gratitude has opened new prospects to me; and who will be so glad to hear of it as you?

“Before I close my letter, you will expect me to say a word more about my health. Sometimes I feel well enough to take my cabin in the next vessel that sails for Liverpool. But there are other occasions, particularly when I happen to over-exert myself in walking or riding, which warn me to be careful and patient. My next journey will take me inland, to the mighty plains and forest of this grand country. When I have breathed the health-giving air of those regions, I shall be able to write definitely of the blessed future day which is to unite us once more.
