4to (239 x 167 mm). Title written in red and black; 90 numbered manuscript leaves in Italian, in ink, with 3 in-text tables; 6 manuscript folding tables and 18 manuscript figures on four folding leaves with red wash coloring at end. (Some minor mostly marginal soiling or browning, title with contemporary pasted overslip, a few short tears to folds of plates.) Contemporary half vellum, marbled boards, hand-lettered on spine (some minor soiling.) 

The text is divided into sections on Arithmetic (76 pp.) and Geometry (14 pp.), each with an introduction, history, presentation, object and divisions. These paragraphs are followed by propositions in the arithmetic section, and addenda on conics, parabola, and other subjects in the geometry section. The detail information in the geometry section leads to a practical problem solving for surveying. The manuscript was likely used for teaching students, possibly at a Capuchin monastery.
