This is not the only instance in the history of anatomical discovery where the name of a person, not its discoverer, has been given to an organ. Allusion has been made to Fallopius as a botanist; a genus of plants, _Fallopia_, has been named in honor of him”. Fallopius was appointed professor of anatomy at Pisa, in the year 1548; and later, at the instance of the Grand Duke of Tuscany, Cosimo I., he received a professorship at Padua, as successor to Vesalius. Besides the chair of anatomy and surgery and of botany, he also held the office of superintendent of the new botanic garden in that city. Fallopius remained in Padua to the day of his death, which occurred in 1562. He was very properly succeeded by his favorite pupil, Fabricius ab Aquapendente, who had been for some time previously his anatomical demonstrator. His collected works, as published in Venice, 1606, embrace twenty-four treatises distributed in three folio volumes. Only one of his works was published during his lifetime, namely, his _Observationes Anatomicae_, Venice, 1561, which is considered one of his most valuable books, containing, as it does, most of his discoveries and his animadversions on the works of other anatomists. This was written as a supplement to the anatomy of Vesalius, for it follows the same order, passes upon the same subjects, corrects the inaccuracies of the Vesalian treatise, and supplies what is wanting. Throughout the work Fallopius treats Vesalius with great respect, and never mentions him without an honorable title. Vesalius wrote an answer to this work, entitled, _Observationum Fallopii examen_, in which he acknowledges the courtesy of Fallopius, but, as argument progresses, appears to be out of temper. After the death of Fallopius it was thought that no successor except Vesalius could be found competent to fill his place. Accordingly Vesalius was chosen. The news of his appointment reached him while he was returning from a pilgrimage to Jerusalem. Unfortunately he was shipwrecked and perished, otherwise history would have afforded an example of the master filling the chair of the pupil. John Philip Ingrassias
