PROLAPSUS OF THE BLADDER. 299 



Prolapsus of the Bladderr— <^ows, during and 

 after difficult calvino; there will be sometimes observed a

 the vulva. This is the blad'der holding the urine, and is 

 twisted at its neck, and therefore, cannot be emptied.

 der back into its place. 



Should the bladder again return a tampon — a roll of 

 soft cotton cloth should be used to plug up the vulva for 

 an hour or two, andif this should not be sufficient, a stick 

 or suture of stout saddler's silk, or other strong material 

 should be passed through each side of the vulva with a 

 small packing or darning needle and letting it remain for 

 a few da vs. 



Diseases of the urinary bladder are many, and diverse 

 from one another, and having pointed out the most common 

 forms of disease of this organ, I will simply mention by 

 name others not so often seen, or at all events observed. 

 Distension, causing abdominal pain, eversion, extroversion, 

 inversion, causing painful urination, inflammation, paraly- 

 sis, causing difficult, and in some cases entire stop'page of 

 the urinary flow and rupture of the bladder, polypi in 

 the bladder, causing frequent urination, and the urine 

 small in quantity. Milch cows are chiefly the subjects of
