Dr. Richard Humphreys spoke as to the symptoms of the illness and his prescriptions, and that he had not suspected poisoning until it was suggested to him and his colleague, Dr. Carter, and that he had _himself administered arsenic_ to the deceased, in the form of Fowler’s solution, on the Sunday or Monday before death, and that he refused _a certificate of death only because arsenic had been found on the premises_. Dr. William Carter spoke of being called the Tuesday before death, and he agreed with Dr. Humphreys that an irritant poison, most probably arsenic, was the cause of death. Dr. Alexander Barron gave evidence to the effect that he was unable to ascertain _any particular poison_. Mr. Edward Davies, the analyst, was called, and gave evidence to the effect that he had found _no weighable arsenic_ in the portions of the body selected at the post-mortem, but that he had subsequently _found one fiftieth of a grain of arsenic_ in a part of the liver, nothing in the _stomach or its contents, but traces, not weighable_, in the intestines, and that he had found arsenic in some of the bottles and things found in the house after death and in the Valentine’s meat juice. The first issue which the jury at the trial had to determine was whether it was proved beyond _reasonable_ doubt that the deceased died from arsenical poisoning. Mr. Justice Stephen, in his summing-up, put this issue to the jury in the following words: “It is _essential_ to this charge that the man _died_ of arsenic. This question must be the foundation of a verdict unfavorable to the prisoner, that he _died of arsenic_.” It must be assumed that this was a question exclusively for medical experts, notwithstanding which the judge, in summing up, told the jury: “You must not consider this _as a mere medical case_, in which you are to decide whether the man _did_ or _did not die of arsenic poisoning according to the medical evidence_. You must _not consider it as a mere chemical case_, in which you decide whether the man _died from arsenic which was discovered as the result of a chemical analysis_. You must decide it as a _great and highly important case_, involving in itself not only medical and chemical questions, but involving in itself a most highly important _moral question_.” MAYBRICK DIED A NATURAL DEATH
