Anatomy — It is well to remember that the fallopian tubes and horns of 

 the uterus in sows are extremelj^ long in comparison to their length in other 

 animals, and that their course is decidedly tortuous in the pelvic aM 

 abdominal cavities. The importance of this can be more thoroughly com- 

 prehended and appreciated by carefully observing these parts and their 

 relation, which is plainly illustrated — in a diagrammatic way — in Fig. 169.
