o pressure. Hypertrophy of the muscular coat of the pyloric
region is an infrequent congenital gastric anomaly in infants,
preventing the passage of food into the bowel, and causing death in a
short time. Incomplete closure of the vitelline duct results in the
presence of a diverticulum--Meckel's--generally connected with the
ileum, mainly important by reason of the readiness with which it
occasions intestinal obstruction. Idiopathic congenital dilatation of
the colon has been described.

Traction diverticula of the oesophagus not uncommonly occur as sequels
to suppurative inflammation of cervical lymphatic glands. More
frequently dilatation of a section is met with, due as a rule to the
presence of a stricture. The stomach often diverges from the normal in
size, shape and position. Normally capable in the adult of containing
from fifty to sixty ounces, either by reason of organic disease, or as
the result of functional disturbance, its capacity may vary enormously.
The writer has seen post mortem a stomach which held a gallon (160
ounces), and again one holding only two ounces. Cancer spread over a
large area and cirrhosis of the stomach wall cause diminution in
capacity; pyloric obstruction, weakness of the muscular coat, and
nervous influences are associated with dilatation. A pec
