Arrowsmith
- 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.†
Chpt 37
- 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.†
Chpt 38
- 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?†
Chpt 38 *
- 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.†
Chpt 38
- 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.†
Chpt 38
- They constructed artificial body fluids (carefully, painfully, inadequately), they tried the effect of the derivative on germs in this artificial blood—and failed.†
Chpt 38
- 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.†
Chpt 38
- But his quinine derivative research had gone on solidly, and he did not regret leaving McGurk.†
Chpt 39
- They wanted to study further the exact mechanism of the action of their quinine derivatives.†
Chpt 40
Definition:
-
(derivative) something developed from something elsein various senses, including:
- a mathematical value from a function -- as in "We can derive X from Y," or "X is a derivative of Y."
- a type of investment whose value is based on another value -- as in "We provide various derivatives that can protect against inflation."
- a work of art such as a film or painting that lacks ideas not previously expressed in other works of art -- as in "Her work is too derivative to interest me."
- work based upon or influenced by prior work -- as in "The book surveys psychological ideas derivative of, but not totally dependent on B.F. Skinner."
- a word based on another word -- as in "Quickly is a derivative of quick."
editor's notes: When used in an artistic context, derivative is often intended to imply a lack of creativity.
