Castes and Tribes of Southern India is a seven-volume encyclopedia of social groups of Madras Presidency and the princely states of Travancore, Mysore, Coorg and Pudukkottai published by British museologist Edgar Thurston and K. Rangachari in 1909.The seven-volume work was one of several such publications resulting from the Ethnographic Survey of India project which was formally instituted by the Government of British India in 1901. The Survey was intended to record details of the manners, customs and physical features of Indian castes and tribes using in part the anthropometric methods that had first been used in India by Herbert Hope Risley for his survey of the tribes and castes of Bengal. Eight years of funding was allotted for the purpose.Edgar Thurston was the son of Charles Bosworth Thurston of Kew, London. Schooled at Eton College, he then studied medicine at King's College, London, qualifying as LRCP in 1877. He worked as a medical officer in Kent County Lunatic Asylum and became a curator of the museum at King's College before joining the Madras Museum in 1885 as a superintendent.The British government in India appointed a Superintendent of Ethnography for each province. Thurston, who had been Superintendent of the Madras Government Museum since 1885, had already conducted some ethnographic work in his studies of the hill tribes of Nilgiris District, published in 1894, and elsewhere. He was appointed Superintendent for Madras Presidency, while L. K. Ananthakrishna Iyer and N. Subramania Iyer were respectively appointed Superintendents for the princely states of Cochin and Travancore. The reports for the two princely states were later integrated with Thurston's work to form the Castes and Tribes of Southern India, as were the results of Thurston's earlier researches into the hill tribes.[citation needed] The state of Mysore was allocated to Thurston for an anthropometric survey but excluded for the ethnographic survey.[citation needed] In his investigations in the Madras Presidency, Thurston was assisted by K. Rangachari of the Government Museum.Nature magazine, in its September 1910 issue, described the work as"a monumental record of the varied phases of south Indian tribal life, the traditions, manners and customs of people. Though in some respects it may be corrected or supplemented by future research it will long retain its value as an example of out-door investigation, and will remain a veritable mine of information, which will be of value."
