Pars Altera. 2 p.l., 90 pp. Bologna: Pisari, 1691. First editions and fine copies. Guglielmini (1655-1710), studied mathematics and medicine at the University of Bologna. He was one of the leading hydraulic engineers of his time and took the professorship of mathematics at the University of Padua. In 1702, he became professor of medicine at the same university, reflecting his varied and changing interests. “The six books of Guglielmini’s work on hydrostatics appear here in their entirety. According to the author, this text presents an entirely new method of measuring flowing water... “Book one sets forth a general doctrine concerning velocity; the second sets forth the measure of water flow in a single inclined canal; the third concerns the measure of water flow in a horizontal canal, either alone or joined with another horizontal. Book four concerns the measure of flowing water in an inclined canal joined in any manner whatsoever. Book five considers horizontal, vertical, and inclined canals. Book six concerns the fundamentals of the proportional distribution of water from aqueducts, or canals and reservoirs... “An appendix [the Pars Altera] contains a table with examples of its use in measuring flow in an inclined canal, in a horizontal canal, and in canals joined in any manner whatsoever after the rule in book four.”–Roberts & Trent, Bibliotheca Mechanica, p. 151. Fine copies. Ex Bibliotheca Mechanica. ❧ Riccardi, I, 642. Rouse & Ince, History of Hydraulics, pp. 68-71.
