The umbilicus as viewed from its peritoneal side. Varieties of the fibrous ring. Disposition of the vessels. Peri-umbilical veins. Varieties of umbilical fascia. Elevation of the peritoneum in the form of a mesentery. Peritoneal fringes containing fat. Diverticula. Clinical examples of defects of the abdominal wall. Relation of the outside of the umbilicus to the peritoneal side. The umbilicus in animals. The lymphatics of the umbilical region. The sensory nerve-supply of the umbilicus. The skin umbilicus. The amniotic umbilicus. Absence of the umbilicus. . The umbilicus during pregnancy. KUsTeER, in 1874, in his paper, ‘“‘ New Growths of the Umbilicus in the Adult ‘and Their Operative Treatment,” briefly refers to the anatomy of the umbilical region. He enumerates the layers of the abdominal wall in the region of the umbilicus as follows: . The skin. The superficial fascia and more or less fat. The superficial sheath of the abdominal muscle. The rectus abdominalis. The deep layer of the sheath. The subperitoneal connective tissue. . The peritoneum. ia the mid-line of the abdomen layers 3-5 are replaced by a thick cord of connective tissue, forming the linea alba, which, at the umbilicus, may reach 1 cm. in breadth. The umbilical scar contains four fetal structures: (1) the umbilical vein, which passes to the liver along the suspensory ligament; (2) and (8), the umbilical arteries, passing downward and outward to the bladder; (4) the urachus, which passes to the bladder.

Catteau in his thesis, in 1876, on the Umbilicus and its Modifications in cases of Abdominal Distention, refers in some detail to the appearance of this region,
