Dr. Stevenson also stated that the general symptoms of arsenic poisoning appeared _within half an hour_ of taking some article of food or medicine, and were nausea, with a sinking sensation of the stomach; vomiting, which, unlike that produced by any ordinary article of food or drink that disagrees, afforded as a rule no relief and often came on again; that there was most commonly pain in the stomach, diarrhea; after a time the region of the stomach becomes tender under pressure, the patient becomes restless, often bathed in perspiration; the throat is complained of; pain in the throat, extending down to the stomach; the tongue becomes very foul in appearance and furred. There is not a bad smell as in the ordinary dyspeptic tongue, a rapid and feeble pulse, thirst, great straining at stool, vomits and evacuations frequently stained with blood. Of fourteen symptoms of arsenic poisoning named by Dr. Stevenson, Mr. Maybrick exhibited _only one_, according to the testimony of Dr. Stevenson. With the exception of the foul tongue with malodorous breath, none of these symptoms coincided with those given by Drs. Humphreys and Carter, who were in attendance on the patient, while Dr. Stevenson _never saw him_. MEDICAL EVIDENCE FOR DEFENSE Then came the evidence for the defense, rebutting the presumption that death was caused by arsenic. First in order being Dr. Tidy, the examiner for forensic medicine at the London Hospital, and also, like Dr. Stevenson, employed as an analyst by the Home Office. This witness stated that, within a few years, close upon _forty cases of arsenical poisoning_ had come before him, which enabled him to indicate the recurring and distinctive indications formed in such cases. Dr. Tidy describes the symptoms of arsenic poisoning as purging and vomiting in a very excessive degree; a burning pain in the abdomen, more marked in the pit of the stomach, and increased considerably by pressure, usually associated with pain in the calves of the legs; then, after a certain interval, suffusion of the eyes--the eyes fill with tears; great irritability about the eyelids; frequent intolerance of light. Dr. Tidy added that there were three symptoms, such as cramps, tenesmus, straining, more or less present, but the prominent symptoms were those he had mentioned, especially the sickness, violent, incessant sickness, and that poisoning by arsenic was extremely simple to detect. Further, that he (Dr. Tidy) had known cases where one or more of the four symptoms mentioned had been absent, but he had never known a case in which all four symptoms were absent; and stated that he had followed every detail of the Maybrick case so far as he could, and had read all the depositions before the coroner and magistrate, and the account of the vomiting did not agree with his description of excessive and persistent vomiting, and was certainly not that kind of vomiting that takes place in a typical case of arsenical poisoning.
