    III. MALrORMATIONS OP THE HEART. 1. MALFORMATIONS DEPENDANT ON ARREST OF DEVELOPMENT AT AN EARLY PERIOD OF FCETAL LIFE. HEART CONSISTING OF TWO CAVITIES. Heaets consisting of only two cavities, an auricle and a ven- tricle, with a single vessel supplying both the systemic and pul- monic circulations, have, though rarely, been found in infants which have survived for a short period after birth.^ If we except the cases of Pozzi^ and Lanzoni,^ which are too imperfectly de- scribed to be relied upon, the first instance of this description of malformation was related to the Eoyal Society by Mr. Wilson in 1798.^ Since that time an example of biloculate heart occurred to Dr. Farre in 1814,® and a specimen was presented to the Pathological Society by Mr. Poster in 1846.'^ A heart exhibiting a somewhat more advanced degree of develop- ment was described by Mr. Standert,'' in the Philosophical Transactions for 1805, and a similar case was met with at Phila- delphia, by ]Mr. Maurau, in 1827,^ and others have since been described by M. There,® Dr. Crisp, Professor Owen and Mr. Clark, and Dr. Yernon.^' ■■ Otto, in his Pathological Anatomy, (South's translation, pf). 269, 270,) refers to cases in which, in im]Derfectly formed fcetuses, the heart has consisted only of an expanded vascular trunk, or a single valveless cavity. ^ Miscellanea C^uiosa, Med.
