Dr. Miller had taken home a two teaspoon sample of stomach fluid but had to wait to test it because his whole family was sick. One of the telltale signs of arsenic is a garlicky odor, but he said when he was doing the test he had a cold so he couldn’t smell a thing. He had done the Marcets test among others and concluded positively that arsenic was present. He had also found that the residue was, as suspected, opium. Dr. Miller testified that if Casler had given Caty a big arsenic dose on Sunday, she certainly wouldn’t have stopped puking by Monday unless the effects had been arrested by something else. He said he had seen a person live as long as two weeks after being poisoned, but in that case, the patient had been too weak to puke after the second dose.

Dr. Delos White’s testimony was similar to Dr. Miller’s but he added that he had found opium in the intestines as well as the stomach. He said hadn’t smelled the characteristic garlic odor of arsenic either but attributed that to the burning of tar in the room and the smell of the corpse. Young Dr. White had done the tests and reached the same conclusions as Dr. Miller – no doubt in his mind that arsenic was present. He added that the intricate Marcets test, done with glass rods was considered to be infallible. He then listed the symptoms of arsenic poisoning, which matched Caty’s right down to her hair falling out after death.

Dr. Joseph White testified that he knew Caty when she was alive and she had a burn scar on her left arm that positively identified her. Dr. White had taken the stomach home with him and locked it in a cabinet until he could look more closely at it. Six weeks later he performed his experiments and swore that his results were not inconsistent with arsenic.

He went on to testify that a half ounce of opium would kill twenty people who weren’t used to it and would kill one person with no tolerance in 12 hours. The testimony Dr. White then gave was what he must have yearned to tell the jury two years later in the Foster trial. He explained that one huge dose of arsenic would not likely kill a person due to the fact that the puking and the water that was usually drunk due to extreme thirst would wash the arsenic out of the system before it had a chance to adhere to the stomach lining. In Caty’s case, opium had allayed the stomach spasms long enough to give it time to kill her.
