Libri hactenus desiderati, probably not before 1684

A short list of partial titles Gregory wished at this moment to acquire. They are about mechanics, mostly, and optics. Thus they may well go with item Coll-33/Quarto A [46], on the reverse, at least generally, apparently part of his Edinburgh lecture notes about the same. In the lower right is a label referring to the reverse side: the document was once folded and stored that way.
