Hernia occurring at the navel. This affection happens more frequently in infants, and takes place by the umbilical ring. In adults, it occurs more commonly in females than in males; and, when it does so, the sac passes in the vicinity of the umbilicus. The organs, found in this kind of hernia, are particularly,- the epiploon, the jejunum, the arch of the colon, and some­times the stomach. The tumour is, in general, round, and presents all the characters of hernia. It is, commonly, really reducible, and not sub­ject to strangulation. It must be reduced, and retained by an elastic bandage, made in the form of a girdle, and furnished with a pad at its middle part. When strangulated, the stricture may be divided upwards and towards the left side.
