Nymphotnayiia 185 



lation of urine in the vagina [urovagina {Vagi7ia 2irinalis)\. 

 This malady attacks old, feeble, nj'niphomaniac cows with large, 

 wide vaginae and uni- or bilateral ovarian cysts. The quantity 

 of urine found in the vagina varies between 500 and 750 grammes, 

 is feebly slimy and shows with the Nessler reagent within 12 

 hours after its removal a marked ammoniacal reaction, and after 

 a few hours standing a very marked ammoniacal decomposition, 

 which undeniably points to cow urine and excludes the sugges- 

 tion of its being some injected fluid or an excretion discharged 

 from the uterus. The accumulation of urine in the vagina is 

 explained by the low pressure of the urinary stream while the 

 animal is standing and the low lying, excavated vaginal floor 

 about the urethral opening. 



The external os in cases of nymphomania in cows which have 

 recently calved, also in all prolonged and well developed cases of 

 nymphomania, is constantly penetrable for a lead pencil, little 

 finger, index finger or, in cows very recently calved, for two 

 fingers, and it was only in very recent cases of nymphomania 

 and along with the existence of acute and severe chronic infec- 

 tious nodular vaginitis (and especially when the latter has been 

 handled with powerful irritants) that the os uteri was found 

 closed in spite of the existence of cystic degeneration of the 

 ovaries and sinking of the broad pelvic ligaments. Frequently 

 the external os is penetrable for one or two fingers while further 

 forward it is much narrowed or entirely closed. 



Under normal conditions, in non-pregnant cows and heifers 

 which are not in estrum or have not been for a few days, as well 

 as in those nymphomaniac cows in which the internal os is 

 closed, there is found on the external os only a very .small clot of 

 a clear, tough mucus, while, in all cases of nymphomania with 

 completely open os uteri, there is as a rule a hypersecretion. • 



The exudate discharged from the cervical canal and ostiuyn ex- 

 termim and accumulating first in the vagina in varying quantity 

 consists usually of vitreous, transparent, tenacious mucus ; 

 more rarely of slimy, whitish, or yellowish white, thick or thin 

 liquid pus, which, in cases of prolapse of the vagina or mouth 

 of the uterus, may in addition be mixed with fecal particles. 



If closed, the os uteri is small, not at all or but slightly swollen, 

 and is often recognizable merely as a small rosette, which may be 

 moved backwards or forwards and projects but little beyond the
