    a passage which his predecessors had regarded as impermea- ble. He gives no account of the anatomy of the internal ear, although he compares it to a labyrinth, a name which Fallo- pius, fourteen hundred years later, fastened on it forever. There is no record of the ossicula auditus until the fifteenth century. Two Italian anatomists, Achilini and Beren- 1480] gario, were the first to describe these bones, although they were not the discoverers of them. Berengario also first described the membrana tympani with exactness. The exactness of his knowledge may be shown by the fact, that he was doubtful whether the origin of the membrane was from the acoustic nerve, or the meninges of the brain. 1542] Andreas Vesalius, who is said to have been the most accurate anatomist of his day,* described the long pro- cess of the malleus, the Eustachian tube, the vestibule, and the semicircular canals. 1604] The honor of the discovery of the stapes bone is claimed by no less than three anatomists, viz., Ingrassia, Columbo, and the renowned Bartolommeo Eustachius. The former wrote commentaries upon Galen's works, that were published long after his death. He claims to have shown it to his scholars in 1546, at Naples. 1523-1582] Gabriel Fallopius, of Modena, died in the bloom of youth, at the age of 39,t but he lived long enough to accomplish much for anatomical science. He showed, among other valuable points in the anatomy of the ear, that the mas- toid cells communicated with the cavity of the tj^mpanum. He described the fenestrse rotunda and ovalis, and gave his name to the canal in which runs the facial nerve in its passage through the cavity of the tympanum, acgumduct is Fallopii. The great Cuvier regarded Vesalius, Eustachius, and Fallo- pius as the three anatomists of the sixteenth century to whom belongs the honor of having restored the science of ana- tomy. 1500-1574] Bartolommeo EustacMus described the tensor tympani as well as the stapedius muscle.
