Note 196 — Chapter IX

“An attempt,” says Mr. Justice Stephen, “was made to account for the presence of antimony and arsenic alleged to be discovered by Dr. Taylor, by the suggestion that it might have been contained in the medicines administered to Miss Bankes during her life. Arsenic is generally found in bismuth, and for three or four days doses of bismuth, containing five or six grains, were administered to Miss Bankes. Dr. Richardson put the proportion of arsenic in bismuth at half a grain to an ounce, and as an ounce contains 480 grains, each dose would have contained about 1/140 of a grain of arsenic. If, therefore, Miss Bankes took twelve doses of bismuth, she would have taken between one-eleventh and one-twelfth of a grain of arsenic in four days. This seems (for it is not perfectly clear), from Dr. Bird’s evidence, to have been more than a week before the day on which he obtained the evacuation analysed by Dr. Taylor, and in 4 oz. of which he said he found nearly a quarter of a grain.”—History of Criminal Law of England, Vol. III., 459.
