EUSTACH'IUS, BARTOLOMMEO, an Italian anatomist, who was b. in the early part of the 16th c., and died in 1574. Few particulars arc known regarding his life, but we learn from the introduction to one of his works, that in 1562 he was professor of medi cine in the Collcgio della Sapienza at Rome. His name is indelibly associated with anatomical science, .through his discoveries of the tube in the auditory apparatus, and the valvular structure in the heart, which have been called after him. He was the first to give an accurate description of the thoracic duct, and was probably the first to notice and describe the stapes (one of the chain of small bones crossing the tympanic cavity of the ear), a discovery which. however, Fallopius assigns to Ingrassias. He likewise con tributed materially to the diffusion-of more accurate knowledge regarding the develop ment and evolution of the teeth, and the•,structure of the kidney. These discoveries are recorded in his Opuscula Anatomica, miblished at Venice in 1563. He was the first
anatomical writer who illustrated his works with good engravings on copper. The Tabular Anatomic,ce, which he was probably unable to publish in consequence of the poverty of which he complains in the introduction to which we have already referred, did not appear until 1714, when they were edited, with explanatory remarks, by Lancisi. Their value is sufficiently evidenced by the fact, that Albinus published a new edition, with an excellent Latin commentary, in 1743, at Leyden; that Bonn published a Dutch edition in 1798 at Amsterdam; and that a German edition appeared in 1800. Lauth, in his History of Anatomical Discovery, remarks that if the Tabuke had appeared in E.'s life time, anatomy would have attained the perfection of the 18th c. nearly 200years earlier. E., Vesalius, and Fallopius may be regarded as the three great founders of modern anatmlifiniti rniif - Diniti7pel by Mirremnft
