The collection, 1835-1850, contains letters and printed papers, notices and unpublished printed material, which Airy received during his time as a member of the Senate of the University of London. The Airy correspondence has a special importance because much of the early archival material of the University of London was destroyed and so often the only record of its activities is in the Senate and Committee Minutes. Airy was particularly interested in the constitution of the University, the developments of the mathematics syllabus, the syllabuses for certificates in hydrography and civil engineering and the introduction of the religious examination.
