[Ophthalmology] Jacob Hovius. Tractatus de circulari humorum motu in oculis

Editio nova, tam re, quam figuris a praecedenti in plurimis mutata. Zui accedit Epistola apologetica, in clarissimum virum D.D. Fredricum Ruyschium (...). Leyden, J.A. Langerak, 1716, (20),103 p., w. 7 (large) fold. engr. plates, contemp. speckled hcalf, ribbed and gilt spine w. mor. letterpiece.

Without the errata-pages at the end, as usual. Library (cancel) stamps on title-p., occas. a bit foxed/ browned, but otherwise a very good copy, with old owner's entry "H.C. de Fremerij" (apparently a medical professor in Utrecht) on first free endpaper. The first edition appeared in 1709. Hovius is known as the discoverer of the "Canal of Hovius".
