In mostexamples of imperforate pharynx the oesophagus is connectedwith the lower end of the pharynx by a fibrous band, whichindicates that the two structures were originally continuousbut that their continuity has been disturbed by secondarychanges (Fig. 824). The constant association of an oesophago-tracheal fistulawith imperforate pharynx indicates some relation between the 614 PSEUD0-GYST8 two conditions. The explanation which at once suggestsitself is, that it may be due to some influence exercised bythe pulmonary diverticulum which leaves that portion of theembryonic fore-gut ultimately represented by the subject has been handled with
