roundings, slight pyaemic fever, emaciation, lumbar weakness 

 and septicaemia. Now and then the abscesses break into the 

 vagina, following which complete recovery may occur. Severe 

 penetrant wounds of the rectum lead to fatal hemorrhage or 

 septic peritonitis. 



G. Fatal Hemorrhage From the Ovarian Artery. 



(^Hemorrhagia arterice ovaricce. ) 



The most to be dreaded and certainly also more common sequel 

 of ovarian operations than generally believed, is the slow bleed- 

 ing to death from the ovarian arteries. Because of the non- 

 vascularity of the capsule in peripheral ovarian cysts, hemorrhage 

 does not occur from them, but serious or fatal hemorrhage is at 

 times observed after the dislodgement of corpora lutea by com- 

 pression, after severe crushing and laceration of the ovaries, and 

 is possible also after the inadvertent tearing away of the ovary 

 from its attachments. In ovaries affected with angioma and 

 blood cysts, fatal hemorrhage may readily be caused. 



In the last case, which is very rare, the ovary feels soft, elastic, 

 flabby, spheroidal, varies in size from that of a man's fist to a 

 child's head and, in case of an angiom, possesses a spherical or 

 slightly nodular character. Upon pressure, the angiom dimin- 

 ishes in size but when the compression is removed the refilling of 

 blood soon restores it to its former dimensions. We have twice 

 had the opportunity of observing cows in which ovarian angioma 

 had been lacerated through improper handling, followed by severe, 

 though not fatal, intra-abdominal hemorrhage. 



The S3'mptoms which serve to indicate ovarian hemorrhage 

 and which appear a few hours after the operation are as follows : 

 decreased or wholly suspended appetite, fullness in the upper 

 flank, weariness, weakness, quickening of the" respiration, violent 

 heart beat, feeble pulse, muscular tremblings, cold horns, ears 

 and feet, anaemia of the visible mucosa and the skin of the udder. 

 D^ath usually follows 15-36 hours after operation. 



Aside from these fatal hemorrhages, others of a less serious 

 character occur and become spontaneously stopped. The condi- 

 tion may cause a more or less complete loss of appetite and rumin- 

 nation for one or two meals and a varying degree of fullness in 

 the upper flank region. After 24-96 hours the animals recover
