Morgagni was the founder of modern pathological anatomy. The work was completed in Morgagni’s 79th year and consists of a series of 70 letters reporting about 700 cases and necropsies. As best he could, he correlated the clinical record with the post–mortem finding. Morgagni gave the first descriptions of several pathological conditions. He was Professor of Anatomy at Padua. Selections from the above work are reproduced in Med. Classics, 1940, 4, 640-839. English translation by B.

Italian text and English translation of 100 clinical consultation lettes written by Morgagni, discussing patients that in most cases he had not seen, a practice that was considered acceptable at the time.  Morgagni gave these, along with 14 folio volumes of his writings to his favorite pupil Michele Girardi. They were edited and annotated by Enrico Benassi and published in Italian in 1935. Jarcho translated and annotated Benassi's text and added a new preface and many footnotes.
