THE PROGRESS OF SCIENCE.
former occupied himself with the structure of the kidneys,
and made mention of the excretory tubes (ducts of
BELLINI).* On the other hand, the discovery of the valve
named after him at the opening of the vena cava inferior
into the auricle is wrongly ascribed to him, for it was
known at an earlier period. But he improved the knowledge
of the organ of hearing, observed the tympanic
muscles, the spiral form of the cochlea, and the trumpetshaped
tube which bears his name to the present day; he
also left an excellent description of the base of the brain.
FALOPPIUS, the gifted pupil of VESALIUS checked with
scrupulous care the discoveries of his teacher, correcting
and 'completing them by a multitude of new facts.
With VESALIUS he was the greatest contributor to the
reformation of anatomy. He furnished valuable information
upon the development of the bones and teeth, described
the petrous bone more accurately, enriched myology by
admirable descriptions of the muscles of the external ear, of
the face, of the palate, and of the tongue, made explicit
statements upon the anastomotic connections of certain
blood-vessels, for instance of the carotid and vertebral
arteries, and discovered the nervus trochlearis. We owe
to him some advance in the anatomy of the organs of sense.
He instituted accurate investigations upon particular parts
of the organ of hearing and of the eye, by which he was able
to give fuller information upon the ligamentum ciliare, the
tunica hyaloidea, the lens, and other anatomical points. So
too in the case of the female sexual organs ; the oviduct
(known in anthropotomy as the Fallopian tube) has immortalized
his name in anatomical terminology.
Of the remaining anatomists of this period the following
rendered services to the development of their science:
INGRASSIAS, by his labours in osteology especially by his
discovery of the stapes and of the inferior turbinated bone,
ARANZIO, who made researches into the anatomy of the
foetus, VAROLIO, of whom the pons reminds us, by his
