Strange Case of Dr. Jekyll and Mr. Hyde
How we cite our quotes:
But the temptation of a discovery so singular and profound at last overcame the suggestions of alarm. I had long since prepared my tincture; I purchased at once, from a firm of wholesale chemists, a large quantity of a particular salt which I knew, from my experiments, to be the last ingredient required; and late one accursed night, I compounded the elements, watched them boil and smoke together in the glass, and when the ebullition had subsided, with a strong glow of courage, drank off the potion. (10.3)
After creating the potion, Dr. Jekyll is much too curious not to drink it.
