quite narrow at another. The fluid may sometimes be 

 pressed from one horn to the other through the uterine 

 body. This is in sharp contrast to the distended uterus of 

 pregnancy, in which, if the pregnancy is healthy, the dis- 

 tension is firm and the contained fluids fixed in the fetal 

 membranes. If a careful record is made of the volume of 

 the uterus, and it is re-examined thirty days later, the uterus 

 of pregnancy will have enlarged markedly; distension of a 

 uterus arrested in development would have remained essen- 

 tially static.

The mole, or uterine cyst, may also confuse. Like the 

 uterus of arrested development, the mole may remain static 

 for months and the uterus may be flaccid. In this instance, 

 however, the genital organs are anatomically sound, there 

 is a corpus luteum of pregnancy, probably a typical uterine 

 seal, and a distended uterus, static in size. It can finally be 

 differentiated by sounding the cervical canal. The condi- 

 tion is discussed later. 



As soon as the neuter character of the animal is recog- 

 nized, it should be designated for slaughter, but whether the 

 animal shall be kept until further grown, fattened, or slaugh- 

 tered immediately will depend upon conditions.
