Contemporary half binding in brown leather and stained cream paper over pasteboard. Sewn on four supports. Spine with raised bands and horisontal line-tooling.

Autograph by Zacharias Plantin, probably composed in the first decade of the 18th c. in Uppsala, where he was promoted to Ph. Mag. in 1707. He later became a history teacher and a vicar, and ended his career as dean in Umeå. His Conjectures on Ammonius are mentioned in the transactions of the Societas regiae scientiarum Upsaliensis (Kungl. Vetenskaps-societeten i Uppsala) from 1723.
The MS ended up in Erik Benzelius the Younger’s collection, who was also one of the founders of the aforementioned scientific academy.
