more seldom, vaginal polypi. There also occurs, quite exception- 

 ally, at the line of demarcation between the vestibule and vagina 

 or in the roof of the vagina about a hand's breadth posterior to 

 the mouth of the uterus, a thin walled fluctuating retention cyst 

 the size of a large fist, containing a grayish sero-mucous, odor- 

 less fluid. The location and character of these cysts may best be 

 determined by simultaneous examination per rectum et per vagi- 

 num and through causing the former viscus to glide over the 

 tumor. 



To the symptomatology of nymphomania also belongs the oft 

 observed extraordinarily great relaxation and widening of the 

 vagina, which here and there shows evident, horizontally di- 

 rected scars and a very notably increased facility for palpating 

 this organ, now so much more roomy. 



Very seldom one finds by the os uteri externum an abcess as 

 large as a hen's egg containing thick, white pus and now and 

 then beneath the os tcteri externum- as many as 6 polypoid growths 

 varying in size from a pea to a pigeon's egg, or one to several 

 fluctuating, spherical, cordiform retention cysts of Gaertner's 

 ducts as large as a small hen's egg. 



Not at all rarely, there is found the vestigial remnants of the 

 incompletely resorbed median walls of the Muellerian ducts, which 

 we have already described ', that is, there exists immediately 

 behind the vaginal portion of the uterus, perpendicular bands 

 1-3 fingers in breadth and 1-3 cm. thick. They are. easily en- 

 gaged by the index finger, elastic, nonvascular and, in non-gravid 

 animals with a thoroughly mobile uterus, are readily drawn far 

 back into the vagina. These evidently may interfere, under cer- 

 tain conditions, with the ejaculation of the semen into the cervical 

 canal. 



Contrary to the views of Zschokke, who holds that, in nympho- 

 mania, the OS uteri is closed, we are able to state that the nym- 

 phomania resulting from ovarial cysts is intimately related to 

 the abnormal dilation of the mouth of the uterus and of the cer- 

 vical canal and that it is only very rarely, and chiefly in cases of 

 small cysts occurring soon after calving, that nymphomania ex- 

 ists without dilation of the os uteri. 



Approximately two to three times, annually we find an accunm-
