Rare first and only edition, perhaps the only copy printed on silk, of the dissertation of a Dutch law student, Nicolaas Johannes van Hanswyk, for his doctorate, dated 22 June 1764. It was customary for students from rich families to have their dissertations printed in a limited edition, often with some copies luxuriously bound incorporating, for example, the coat of arms of the family. Here the dissertation was printed on silk and bound in red velvet. Considering the costs, Van Hanswyk probably had only a few copies, or perhaps only one, printed on silk. The dissertation deals with substitutio vulgaris (ordinary substitution), a legal term for the provision of substitute heirs in case the original heir dies or declines the inheritance. The dissertation is followed by some laudatory poems praising and congratulating Van Hanswyk, one in Latin and four in Dutch.
