Not illustrated. 1877 edition. Excerpt: ... 158 CHAPTER XII. Hydatids--Echinococci Of The Liver. Synonymously.--Hydatids are known as the Hydatis of Laennec, and derived from the Greek Vbotiq, a vesicle, from vSwp water; Acephalocystis, from a privative, Keoxtj the head, and Kvant; a vesicle--simply a vesicle without a head; the Vessie sans adherence of Cruveilhier; the Echinococcus Hominis of Eudolphi and Bremser; the Polycephalus Humanus of Zeder; the Fischiosoma of Brera. Nationally.--The Hydatide of the French; the Wasserblasse, Blasenwiirm of the Germans; the Idatide of the Italians, and the Hydatid of the English. Historically.--Physicians at a very remote period were undoubtedly familiar with large cysts of the liver, filled with an aqueous fluid, but were ignorant of their real nature. Hippocrates, A.d. 450, in his 55th Aphorism (section vii.), gives the following: --" When the liver is filled with water and bursts into the epiploon, in this case the belly is filled with water and the patient dies. Galen, some two centuries afterwards, understood this case to refer to Hydatids of the liver, but finds difficulty in explaining how they could burst into the epiploon unless by ulceration. It would seem, says Galen, that our author meant the cavity of the peritoneum. Hartmann, in 1685, directed attention to their being of an animalcular nature. Tyson, in 1691, endeavoured to prove that they were a species of worms, or imperfect animals. Pallas, in 1760, recognised them as parasites, and showed their close connection to the tapeworm--a discovery which was confirmed and extended by Goeze shortly afterwards. The first accurate description however, of a "Human Echinococcus" was given by Bremser in 1821, who traced the relationship of a hydatid to the tapeworm; and it is now...
