A Demonstration of the Peritoneum is best made with a large bag of 

 mosquito- netting, sewn up along all four sides, and having a central slit to 

 represent the incision usually made in the laparotomy operation. Sponges of 

 various sizes will represent the various organs, and may be pushed into folds 

 of the bag and tied in by string, wholly covered or partially covered, as the 

 <ase may be, for each. Professor Pancoast used this method of demonstration 

 in his lectures, making the subject perfectly clear to many who never under- 

 stood it before.
