If, now, to these numerous physiologic departures there be superadded pathologic departures incident to inflammatory processes, some conception of the difficulty confronting the student in his dissecting-room study may be imagined.

Within recent years our standard text-books on anatomy were monumental in their respective chapters on the peritoneum, to the most nagrant violation of perspicuity. ere is no longer doubt that in the study of the abdomial
