Mefenteric Hernia. —It is well known that the mefentery is 
a double membrane, contitling of two layers. When one of 
thefe layers is torn, while the other remains in its natural 
fate, the inteftines m y infinuate themfelves into the aper- 
ture; and form a kind of hernia. The fame confequence 
may arife from an imperfe@ formation of one of the layers.

In fhort, the vifcera may glide into any preternatural open-

which are compofed of two layers. The bowels have thus
