Section passing through the hepatic arch, above the pylorus and through the body and head of the 

 pancreas, to show the situation and origin of the " fasciae of fusion." The pancreatic plica is to be seen 

 above and to the left of the hepatic. In A the fusions have been destroyed and the mesos thereby 

 restored to their primitive independence. In B the adult type is shown. The caput pancreatis and the 

 mesoduodenum lodging it have been turned over to the right. The corpus et cauda pancreatis, contained 

 within the omentum ma jus, lie iu front of the caput pancreatis on the right side, and in front of the 

 posterior abdominal Avail on the left. In B the retropancreatic " fasciae of fusion " may be seen (the 

 fascia of Trietz behind the caput pam-roatis, the fascia of Toldt behind the corpus pancreatis). (From 

 Poirier et Charpy, Traite" d'Anat. hum., Paris, 1901, 2 ed., t. iv. p. 976, Fig/548 A and B.)
