The Papers of Horace Geoffrey Quaritch Wales contain papers relating to his archaeological work in southeast Asia including expedition notes, personal notebooks, diaries, manuscript proofs, correspondence, newspaper cuttings and maps. Listed within this catalogue are objects and items of furniture which were also part of the bequest of Quaritch Wales' wife, Dorothy, to the Royal Asiatic Society.

Typed manuscript entitled, "Chinese Secret Societies in Malaya. Sections K. L. + M. The Chinese factor in the Policy of Intervention" concerning the time period 1872-1876. It is also labelled as "File 5" and "Duplicate". It appears to be an early draft or research material for part of Blythe's book The Impact of Chinese Secret Societies in Malaya published in 1969. The material seems to be in more depth than the corresponding material covered within the publication. With the file is a note which reads, "It is possible that Prof. Cowan at S.O.A.S., London, would like to have this File 5, as it deals with the subject of his book on Intervention".
