The most reliable evidence for associating these defectswith the duct of the yolk-sac is that furnished by specimensin which a persistent duct and a valve coexist. In my earlyobservations I had regarded imperforate ileum as depending CYSTS OF TEE UBAGHUS 599 upon the influence of the vitello-intestinal duct, and sub-sequent observations put the speculation on a sound specimens which demonstrate these views are preservedin the museum of the Middlesex Hospital.
