The papers include full documentation (case histories, experimental notes and data) of Cunningham's medical researches in India, and in particular of his prolonged and exhaustive work on the bacteriology and immunology of relapsing fever, and the major programme on the treatment of rabies which he instituted on his appointment as Director of the Pasteur Institute, Kasauli, (where over 8,000 cases a year were treated). There are also records of the work on vaccine lymph carried out at the King Institute, Madras which was the principal research laboratory and vaccine depot of the Madras area. An important feature of the collection are the many photographs taken by Cunningham during his long service in India. The subjects are both professional and personal, and include the institutes and laboratories where he worked, their personnel, equipment and facilities, his own quarters and family, the scenery and native population of India, and his service at Peshawar during the First World War. Almost all of these bear Cunningham's dates and descriptions. The papers also include Cunningham's reports, press-cuttings and other material relating to the 1927 Calcutta Congress.
