and the least frequent, the posterior part of the ischium and the pubis. 

 Fracture of the sacrum and the internal angle of the ilium is also very 

 rare. Simultaneous compound fracture of the two coxse has been 

 observed in two cases by Lafosse ; in one case by Crepin, and in 

 another by Philippe. 



D'Arboval has witnessed a fracture of the pubis in a Dog ; and 

 Carsten Harms alludes to fractures of the ischium occurring in the 

 Mare and Cow. The latter authority has likewise found the two iliums 

 of a Goat united at their posterior angle by a mass of bone as thick as 

 a finger. Professor Ercolani has well described twelve important 

 cases of pelvic fracture exhibited in the Pathological Museum of the 

 Bologna University. ^ The first of these is a compound fracture of the 

 ossa innominata, the solution of continuity involving all the border of 

 the foramina ovale in the pelvis of a Mare ; the second is a fracture of 

 the left ilium near its neck, and extending to the cotyloid cavity, also

in the pelvis of a Mare ; the third is a compound comminuted fracture 

 of the left innominate bone in a Mare, the piece being divided into six 

 principal portions ; the fourth is a compound fracture of the right ilium 

 of a Mare, extending to the arch of the pubis on the left side ; the fifth 

 is a longitudinal fracture of the right ilium of a Filly ; the sixth, a 

 fracture of the external angle of the right ilium and the left ischiatic 

 tuberosity of a Mare ; the seventh is a slightly oblique fracture of the 

 ilium extending to the cotyloid cavity of a Mare ; the eighth is a com- 

 pound fracture of the pelvis of a Mare, involving the internal angle of 

 the ilium, the external part of the ischial tuberosity, the arch of the 

 pubis, and the union of the pubis with the ischium ; the ninth is a 

 fracture of the superior and posterior crest of the ihum of a Mare ; 

 the tenth is an oblique fracture of the neck of the left ilium of a Mare ; 

 the eleventh is a compound fracture of the right coxa of a Mare, the
