Loose prints originally stored in a variety of photographic wallets and envelopes. None is dated, though some dates can be established where the glass plate negative can be identified. Prints are of landscapes, vegetation, and parts of plants.
Photographs taken during Yapp's participation in the Cambridge University Expedition to the north-eastern Malay states and Upper Perak in 1899-1900, led by William Walter Skeat. The expedition party consisted of W.W. Skeat (Christ's College, Cambridge), Nelson Annandale (Balliol College, Oxford), Richard Evans (Jesus College, Oxford), D.T. Gwynne-Vaughan (Christ's College, Cambridge), Frank F. Laidlaw (Trinity College, Cambridge), and Richard H. Yapp (St John's College, Cambridge). Laidlaw and Yapp joined the party later, in August 1899, and Yapp sailed for England in February 1900. The photographs in this collection date from October 1899 until the end of his trip, though most are undated. Some dates can be determined from published accounts of the expedition and from Yapp's correspondence. The descriptions given in all cases are what is written on the envelope.
