MATERNAL DYSTOKIA. 



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 Univer- 

 sity.* 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 j 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 div-ided 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 compound 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

 Fracture of the Pelvis. 



ischium ; the ninth is a fracture of the superior and posterior crest of the 

 ilium 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 cotyloid portion being completely isolated from the is- 

 chium, ilium, and pubis ; the twelfth is a fracture of the external angle of 

 the ilium. Lanzillotti-Buonsanti states that the Pathological Museum of 

 the Milan Veterinary School contains a coxa, which shows a fracture of 

 the neck of the ilium, with overlapping of the disunited portions; and 

 also a pelvis in which the pubic portion of the symphysis has sustained 

 a comminuted fracture.
