DISEASES OF CATTLE 185 



If the womb has been cut off, injections of a solution of a tea- 

 spoonful of carbolic acid in a quart of water should be employed 

 daily, or more frequently, until the discharge ceases. 



EVERSION OF THE BLADDER. 



A genuine eversion of the bladder is almost unknown in the 

 cow, owing to the extreme narrowness of its mouth. The protrusion 

 of the bladder, however, through a laceration in the floor of the va- 

 gina sustained in calving, and its subsequent protrusion through the 

 vulva, is sometimes met with. In this case the protruding bladder 

 contains urine, which can never be the case in a real eversion, in 

 which the inner surface of the bladder and the openings of the ureters 

 are both exposed outside the vulva. The presence of a bag containing 

 water, which is connected with the floor of the vagina, will serve to 

 identify this condition. If the position of the bladder in the vulva 

 renders it impracticable to pass a catheter to draw off the urine, pierce 

 the organ with the nozzle of a hypodermic syringe, or even a very 

 small trocar and canula, and draw off the water, when it will be found 

 an easy matter to return the bladder to its place. The rent in the 

 vagina can be stitched up, but as there would be risk in any sub- 

 sequent calving it is best to prepare the cow for the butcher. 



RUPTURE OP THE BLADDER. 



This has been known to occur in protracted parturition when 

 the fetus finally passed while the bladder was full. The symptoms 

 are those of complete suppression of urine and tenderness of the ab- 

 domen, with a steady accumulation of liquid and fluctuation on 

 handling its lower part. If the hand is introduced into the vagina it 

 is felt to be hot and tender, and perhaps slightly swollen along its 

 floor. As a final test, if the lower fluctuating part of the abdomen is 

 punctured with a hypodermic needle, a straw-colored liquid of an 

 urinous odor flows out. The condition has been considered as past 

 hope. The only chance for recovery would be in opening the ab- 

 domen, evacuating the liquid, and stitching up the rent in the 

 bladder, but at such a season and with inflammation already started 

 there would be little to hope for. 



RUPTURE OP THE WOMB. 



When the womb has been rendered friable by disease this may 

 occur in the course of the labor, but much more frequently it occurs 

 from violence sustained in attempting assistance in difficult parturi- 

 tion. It is also liable to occur during eversion of the organ through 

 efforts to replace it. 



If it happens while the calf is still in the womb, it will usually 

 bleed freely and continuously until the fetus has been extracted, so 

 that the womb can contract on itself and expel its excess of blood. 

 Another danger is that in case of a large rent the calf may escape into 

 the cavity of the abdomen and parturition become impossible. Still 

 another danger is that of the introduction of septic germs and the 

 setting up of a fatal inflammation of the lining membrane of the 

 belly (peritoneum) . Still another is the escape of the small intestine 

 through the rent and on through the vagina and vulva, so as to pro- 

 trude externally and receive perhaps fatal injuries. In case of
