 in a pregnant cow, either clinically or in the abattoir. In 

 the sow, however, I have one example, shown in Fig. 161, 

 which indicates very clearly that the disease does occur in 

 the pregnant sow, and presumably in pregnant animals of 

 all species. Frequently it follows retained afterbirth and 

 other types of puerperal infection. Since hydrosalpinx is 

 almost always bilateral, its chief clinical manifestation is

 adhesion of the ovary within the pavilion of the tube has al- 

 ready occurred. The mesosalpinx is also commonly adher- 

 ent to the ovary, as shown in Figs. 154, 155 and 156, so that 

 the cystic oviduct is throvVn into a convoluted mass in front 

 of and lateral to the ovary, and in ■ some cases above the
