Folios 1-16, commenting up to Book 2, Title 12, are on different paper and in a different hand; some folios (probably only 2), containing the commentary on Book 2, Title 13, have been lost after folio 16. A substantial number of folios have been lost at the end, as the commentary breaks off in Book 41, Title 2. Dates of delivery, from November 1710 to June 1711, appear regularly in the margins.

It is possible that the lectures are those of James Craig, who became Professor of Civil Law at Edinburgh in 1710, or those of Robert Craigie, later Lord Glendoick, Lord President.
