protruding from between the lips of the vulva, or 

 hanging some distance below the opening. 



Treatment. — The treatment consists in cleaning 

 the parts, with warm water and disinfectants, redu- 

 cing the congestion in the tissues, and returning the 

 mass to its normal position. This is generally no 

 easy task, and may cause the sow a great deal of 

 pain. If the parts are inverted to such an extent as 

 to expose a large part of the lining membrane, it 

 becomes swollen and inflamed, sometimes injured and 

 gangrenous. The size of the tumor-like mass may 

 become greatly increased by the distended bladder, 

 as the canal leading from the bladder is so pressed 

 on that urine cannot be passed. All of the above con- 

 ditions must be relieved before the accident can be 

 successfully corrected. 



To reduce the size of the mass it should be ban- 

 daged, beginning at the outer end and winding to- 

 ward the .body. It is best to use a clean muslin ban- 

 dage about two yards in length. This should be al- 

 lowed to stay on for about ten or fifteen minutes and 

 hot water fomentations used. This should ' be re- 

 peated as often as necessary, or until the tissues are 

 in a fit condition to be returned. When badly injured, 

 or gangrenous, the only thing that can be done is to 

 amputate the mass. 



In returning the organs the finger, or thumb is 

 pressed against the center of the tissues, and they are 

 shoved forward and replaced in their normal position. 

 They are then retained in position by taking a few 

 stout stitches across the opening and to each side of
