  • They had, they saw, to answer an interesting question: Do the quinine derivatives act by attaching themselves to the bacteria, or by changing the body fluids?
  • They wanted to study further the exact mechanism of the action of their quinine derivatives.
  • They constructed artificial body fluids (carefully, painfully, inadequately), they tried the effect of the derivative on germs in this artificial blood—and failed.
  • But these ambitions he forgot as he came to Terry’s proud proprietary shanty, by a lake among oaks and maples, and heard Terry’s real theories of the decomposition of quinine derivatives.
  • But his quinine derivative research had gone on solidly, and he did not regret leaving McGurk.
  • Terry had discovered that certain quinine derivatives when introduced into the animal body slowly decompose into products which are highly toxic to bacteria but only mildly toxic to the body.
  • Their first task was to determine with accuracy the tolerated dose of the quinine derivative, and to study its effects on the hearing and vision, and on the kidneys, as shown by endless determinations of blood sugar and blood urea.
  • While Martin did the injections and observed the effect on the monkeys and lost himself in chemistry, Terry toiled (all night, all next day, then a drink and a frowsy nap and all night again) on new methods of synthesizing the quinine derivative.
  • He patented the process of synthesizing his quinine derivative and retired to Birdies’ Rest, to build a laboratory out of his small savings and spend a life of independent research supported by a restricted sale of sera and of his drug.

  • There are no more uses of "derivative" in the book.
