He had also found arsenic in a glass of milk in the house, in a vessel in which luncheon had been sent to the office of Mr. Maybrick, in a medicine bottle, and in a bottle of glycerine in the lavatory. In fact, one of the most remarkable features of this case was the number of articles in which arsenic had been discovered. Dr. Stevenson had also found no arsenic in the stomach, but had detected a small quantity in the kidney and the intestines. In a portion of the liver he found an amount which he calculated to amount to one-third of a grain for the whole liver, and he gave as his opinion that "the body at the time of death probably contained approximately a fatal dose of arsenic." Dr. Tidy, in giving evidence on behalf of the accused, criticised this evidence of Stevenson on the grounds that it did not necessarily follow that because one portion of the liver contained so much arsenic, the same proportion must be present in the remainder. In his experience the amounts of arsenic retained might vary in different parts of the same organ. He calculated from the results of Stevenson's analyses that the total amount of arsenic was 0·082 grains. If we examine this evidence more closely it is difficult to see upon what basis Tidy calculated his total. Stevenson had examined approximately one quarter of the liver, and had extracted from two portions a total quantity of 0·076 grains, so that, according to Tidy, the remaining three-quarters could only have contained 0·006 grains of arsenic. On the face of it this seems an absurd conclusion. The evidence of Professor Paul went to prove that arsenic was present in the material of earthenware vessels similar to that in which the lunch was sent to Mr. Maybrick's office, and that it could be liberated by the action of an acid, so that the arsenic found in the particular vessel might have originated from the action of acids in the food itself upon the interior of the vessel. As has been mentioned, one of the points brought as evidence against the prisoner was that a bottle of glycerine had been found in the lavatory, and that this contained arsenic. There was no evidence that the prisoner had ever had this bottle in her hand, and, apart from that, arsenic is a very usual impurity in ordinary commercial glycerine.
