This is the complete set of John Burdon Sanderson’s vivisection licenses, from 1876 to 1905 (the year of his death). The first license is numbered “1”, and is in fact the first license ever issued in Great Britain under the Act of 1876. They are signed in person by the various Home Secretaries, Viscount Cross (Home Secretary 1874), Vernon Harcourt, Henry Matthews, H.H. Asquith (later Prime Minister), etc.
In addition, there are two small notebooks, written by John Burdon Sanderson’s wife, Lady Ghetal Burdon Sanderson, which contain copies of letters written by John Burdon Sanderson and herself, that she recopied into the notebooks, in the course of her research into his life.
