[1] The records of the Joint Expedition to Mesopotamia, undertaken by the University of Pennsylvania and the British Museum, under the directorship of Doctor C. Leonard Woolley, had recently appeared.

    [2] Vance owned some exceptionally fine pointers and setters which had made many notable wins for him in the various trials in the East. They had been trained by one of the country's leading experts, and returned to Vance perfectly broken to field work. Vance took great pleasure in handling the dogs himself.

    [3] It is interesting to note that this same method of selecting and training dealers has been followed at Agua Caliente.

    [4] Kinkaid even employed the European roulette wheels with only the single "0".

    [5] I imagine Kinkaid got his idea for these enormous attendants from the impressive giants in the entrance-hall of the Savoy dining-room in London.

    [6] Snitkin and Hennessey were two of the members of the Homicide Bureau who had participated in several of Vance's famous criminal cases.

    [7] Sergeant Ernest Heath, of the Homicide Bureau, had been officially in charge of all the cases which Vance had investigated.

    [8] The same room, it flashed through my mind, in which the momentous and dramatic poker game was played in the "Canary" murder case.

    [9] Doctor Emanuel Doremus, the Chief Medical Examiner of New York.

    [10] Swacker was Markham's secretary.

    [11] This was the same restaurant to which Vance took us during the investigation of the Kennel murder case, and where he bored Markham almost to the point of distraction with a long dissertation on Scottish terrier characteristics, blood-lines and pedigrees.

    [12] Doctor Hildebrandt, in answering Vance's question, mentioned specifically several poisons which leave no trace in the human body, but I am purposely not recording them here. Modern medical scientists and toxicologists will know those referred to; and I deem it both unnecessary and unwise to make such dangerous knowledge public property.

    [13] As I write this record of the Casino murder case, I note, in a dispatch to The New York Times, that the Imperial Chemical Industries, an important British organization, have begun the commercial production of heavy water and hope in time to be able to supply it to chemists, physicists and physicians the world over, at about fifty dollars a teaspoonful.
