be worn for at least ten days. In cases where it 

 is impossible to return it, mortification will soon 

 set in, or the animal' may die from collapse. In, 

 this case an operation is necessary, and is easily 

 performed, and some cases of recovery have been 

 reported. Tie a ligature tight around the neck 

 of the womb and with a sharp knife remove all 

 external to the ligature. In a few days the liga- 

 ture will slough off, and no after treatment is nec- 

 essarv. 



DROPSY OF, THE UTERUS. 



This disease seldom occurs in the domestic ani- 

 mal. A few cases have been reported. 



The symptoms are those of pregnancy. The af- 

 fected animal is thought to be in this condition 

 until the period of gestation passes without any 

 signs of parturition. Upon examining the womb 

 it is found to be greatly enlarged and fluctuating 

 when pressed upon. 



The treatment consists in opening the mouth of 

 the womb with the fingers and the fluid will es- 

 cape. In some cases a trocar will be required to 

 pass in and draw off the fluid. As there is a tend- 

 ency for the fluid to accumulate again, a cure is 

 impossible; and if the patient be a cow it should 

 be fattened for the butchers. 



MAMMARY GLANDS, OR UDDER. 



This is divided into four compartments in the 

 cow and two in the mare. It is made up of a num- 

 ber of glands well supplied with blood vessels; 

 these glands secrete the milk from the blood.
