[Study on the original Chinese Version of Da sheng bian (A Treatise on Midwifery) translated by William Lockhart].

William Lockhart's A Treatise on Midwifery, published in 1842, is the first English translation Monograph of ancient obstetric book in traditional Chinese medicine.To take the translation postscript as clue, adopt research methods like textual bibliography etc., and integrate the relevant historical data and the libraries collection information, it is found that the original version of the English translation is the carving copy of Da Sheng Bian engraved by Fuxian Hall on Rongxian Street, Foxian County,Guangdong Province, in the fifth year of the reign of Emperor Daoguang of the Qing Dynasty (1825). It is now collected in the National Library of Australia and the Dun's Library of the Royal College of Physicians of Ireland, and the sources of both collections are related to William Lockhart.
