chained_bear commented on the word hyoscine
"Over the previous year he had acquired hydrochloric acid, hydrogen peroxide, morphine salts, and—his highest-volume purchase—cocaine, which he bought on nine occasions throughout the preceding year, for a total of 170 grains. Today, however, he wanted something different. He asked the clerk, Charles Hetherington, for five grains of hyoscine hydrobromide.
... Hetherington knew that Crippen made homeopathic medicines and dental anesthetics, and that hyoscine was sometimes used in drugs meant to have a tranquilizing effect on patients.... but Hyoscine was an exceedingly dangerous poison and was rarely used."
—Erik Larson, Thunderstruck (New York: Crown Publishers, 2006), 176
