Abstract:
The greatest prevalence of Asiatic cholera since the adoption of modern statistics was in 1879. Especially in Okinawa Prefecture, its morbidity rate was the largest in Japan in that year. Dr. Hironobu Tsuchiya, who was appointed as an official of the Department of Inner Affairs, wrote "Ryukyu-kiko" as a private memorandum. He wrote more about the situation of administrative confusion than he did about the condition of Asiatic cholera. This paper also mentions the brief sketch of Tsuchiya's life and the description of the manufacturing methods, effectiveness and use of chemical drugs which are contained in his "Sinyaku-shoko".
