The strange case of Dr. Jekyll and Mr. Hyde

ROBERT LOUIS STEVENSON (1850-1894)

Strange Case of Dr. Jekyll and Mr. Hyde

"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.
The most racking pangs succeeded : a grinding in the bones, deadly nausea, and a horror of the spirit that cannot be exceeded at the hour of birth or death. Then these agonies began swiftly to subside, and I came to myself as if out of a great sickness. There was something strange in my sensations, something indescribably new and, from its very novelty, incredibly sweet."
