luciferous, not lucriferous

Being a bachelor, and through God's bounty furnished with a competent estate for a younger brother, and freed from any ambition to leave my heirs rich, I had no need to pursue lucriferous experiments, to which I so much preferred luciferous ones, that I had a kind of ambition ... of being able to say, that I cultivated chemistry with a disinterested mind.
