DOMESTIC ANIMALS. 33 



a few minutes to prevent the uterus from being forced 

 out again. The organ being in place again it is usually 

 necessary to take steps to prevent another inversion. I 

 have found the following to be very successful : take a 

 large bag needle and thread it with strong tape. Insert 

 two stitches, allowing them to cross each other. They 

 should be inserted rather deeply so as to secure a good 

 hold. In this way a return of the organ or even a por- 

 tion of it very rarely takes place. Another method to 

 prevent a re-inversion is by the application of Delwart's 

 truss, which can be made with an ordinary rope, (fig- 

 ure 6) and applied as in figure 7. Several other 

 contrivances have been used, all having the same end in 

 view, namely narrowing the outlet from the vagina. 

 None of these appliances should be placed so tightly 

 that the animal cannot pass the urine. 



Many seemingly hopeless cases of inversion may be 

 remedied by using the above means. I will give one 

 instance to show the recuperative powers of the organ. 

 Being sent for by a breeder, six miles from my residence, 

 I arrived at the farm in a storm of sleet and rain which 

 had lasted several hours. I found the cow in the field, 

 lying down with the whole uterus protruding. It was 

 covered with darkish purple spots and cold, and to all 

 appearance had no chance of being restored to a normal 

 condition again. I had a sheet brought, and with the 

 necessary assistants we raised the cow and lifted the 

 uterus with the sheet; then led the cow to a shed, where 

 I operated as above explained to return the organ, and 

 placed two stitches across the lips of the vulva. The 

 uterus wac retained and a complete recovery took place 

 in a few days. The uterus retained its normal position.
