horn is a small nodule one centimeter in diameter and projecting about 

 six millimeters above surface of mucosa, which appears to be a small 

 tumor. The mucosa of the middle and anterior portions of left horn is 

 of a light drab but not uniform, color ; there is present a small quantity 

 of a turbid creamy exudate. The mucosa of the right horn is more uni- 

 form and a lighter drab color than that of left horn. The same exudate 

 as seen in left horn is present. A small piece of flat bone, four and one- 

 half centimeters long by one and one-fourth centimeters wide is found 

 lying free in anterior end of horn. There is a cj^st one centimeter in 

 diameter at the fenestrum of right oviduct. Left oviduct apparently 

 normal. Eight ovary is four by four and one-half centimeters and has a 

 cyst two centimeters in diameter. The left ovary is four by five and 

 one-half centimeters and has a cystic corpus luteum four centimeters in 

 diameter. B. coli commuuior was isolated from the uterus. Cultures 

 from cystic ovaries were negative. 



Histological examination: The mucosa of the posterior cervix is cov- 

 ered in places by a simple epithelium twenty to twenty-five microns high 

 and in others by a stratified epithelium, six to eight cells deep, and 

 sixty-five microns high. The mucoid changes of the epithelium are well 

 marked. A faintly pinkish granular exudate containing many small 

 round cells is adherent to the surface in places. The sub-epithelial tissue 

 is but slightly cellular. In the middle and anterior portions of the cer- 

 vix, the mucoid changes of the epithelium are more extensive than in the 

 posterior end. Here the nuclei show distinct degenerative changes. The 

 sub-epithelial zone is distinctly cellular and shows many small round 

 cells and polymorponuclears. The mucosa of the uterine body averages 

 about two millimeters thick. The sub-epithelial cellular zone is not 

 uniform but is absent in places. The deeper portions of the gland mucosa 

 are not uniform. In places there is an absence of glands and the stroma 

 is edematous. The glandless areas are not densely fibrous but are more 

 reticular with here and there sm&ll areas of a more fibrous nature. In 

 the glandular portion of the stroma the periglandular tissue is more 

 cellular than is normally seen. There are no defects of the glandular 

 epithelium but in a few of the gland tubules numerous small round cells 

 are seen. 



The mucosa of the left horn varies in thickness from three to six milli- 

 meters and is covered by an epithelium sixteen to twenty-five microns in 

 height. There are no epithelial defects. There is not a .uniform sub- 

 epithelial zone with a deeper more reticular stroma but the deeper 

 stroma is distinctly denser because of an increase of the cellular and 

 fibrous constituents. There is considerable infiltration of the sub- 

 epithelial tissue with small round cells and an increase in the number of 

 connective tissue cells. However, the small round cell infiltration is not 

 uniform and in places it has the appearance of irregularly shaped folli- 

 cles. The small tumor in the posterior end of horn described in the ma- 

 crosopic examination consists of a cheesy pinkish staining material 

 with a few nuclei scattered throughout the cheesy material. The wall 

 surrounding this mass is lined with low cuboidal ex)ithelium, indicating 

 that'the nodule is due to the plugging of a gland duct with retention and 

 iuspissation of the secretions. A few of the gland tubules show some 

 disintegration of the epithelium with numerous small round cells in the
