In a previous experimental study1 we attempted to reproduce serosal inclusions such as are found at times on the female parietal and visceral peritoneum and showed that when two serosal surfaces are brought together as in a gastro-enterostomy no recognizable serosal inclusions (celomic epithelium) are formed. This result was not unexpected in view of the studies of Ranvier and Marchand,2 Cunningham,3 Foot4 and others. However, we believed it possible that such inclusions might have been overlooked when an investigator was engrossed in some other phase of the problem of the behavior of celomic epithelium. As noted, our search in this respect was fruitless.
On the other hand, we did find that when we employed suture methods on the anterior aspect of gastro-intestinal anastomoses that everted mucosa into the line of apposition between stomach and intestine, then mucosal inclusions (appositional rests or inclusions) similar to those shown
