Held in the British Library. Commonplace book containing the notes of a lawyer connected to the Inns of Court. In a set of pages in the centre of the book are four dances, without names.
I've linked a transcript below. There are also transcripts in Dancing in the Inns of Court, James Cunningham, and The Almain in Britain, c.1549–c.1675, Ian Payne.
