336 MATERNAL DYSTOKIA. 



There are found, in addition, cells or fusiform bodies, as well as somewhat irregular 

 globular bodies with dark contours. 



From the histological characters, Arloing came to the conclusion that the tumor was 

 a fibroid. 



THROMBUS OR HEMATOMA, 



Thrombus or haematoma of the -vagina or vulva, usually appears most 

 frequently after delivery. Pfirter, however, has recorded the case of a 

 Mare in which a large blood tumor, or haematoma, was caused by the rup- 

 ture of blood-vessels and the escape of blood into the connective tissue 

 around the vagina. It formed a great swelling on the sides of the vagina 

 and vulva, the infiltration of blood extending to the perineum. This 

 tumefaction proved an obstacle to parturition ; so that it was necessary to 

 remove it by opening it freely, and taking away the clots of blood which 

 had formed. The haemorrhage which ensued was checked by the injec- 

 tion of a solution of perchloride of iron. 



Saake has observed these blood-kysts most frequently in Swine ; death 

 from haemorrhage has sometimes resulted from their rupture. 



The application of ice or cold water, or perchloride of iron, or even the 

 actual cautery, and plugging the vaginal canal, will generally arrest the 

 bleeding. 



SEROUS KYSTS. 



Kopp, Hering, Ayrault, Lafosse, Liautard, Miiller, and others, have 

 observed serous kysts on the vaginal mucous membrane, and even in the 

 uterus, of the Mare and Cow. 



The vaginal kysts are of variable size, but most frequently as large as 

 a pear, which they are generally not unlike in shape. They are attached 

 to the mucous membrane by a very narrow pedicle, and in some instances 

 appear between the labia of the vulva when the animal is reclining, but 

 disappear again into the vagina when the standing posture is assumed ; 

 though occasionally they are so large that they cannot return without 

 assistance. 



The kyst is smooth and transparent, and contains a clear limpid 

 serosity, in which albuminous flakes are often observed. 



Not unfrequently, the glands of Bartholin in the vagina of the Cow are 

 greatly distended with mucus, serum, or even pus, as a result of inflam- 

 mation. 



Such kysts are not likely to retard parturition, and if they should, their 

 treatment is very simple j as a lancet puncture suffices to evacuate the 

 fluid they contain, and the walls readily adhere and cicatrize. 



Hering has seen them occupy the vagina and extend into the uterus ; 

 and in the latter organ their presence may be more serious than when 

 they are -limited to the vagina. We have given an instance of this, 

 furnished by Liautard {see p. 167), and which shows that they may prove 

 troublesome obstacles to delivery, as well as dangerous to the animal in 

 whose uterus they may have formed. 



When the kyst is attached to the cervix or its neighborhood, it may 

 pass into the os and obstruct it, and thus prevent the foetus passing 

 through. When very large it may so closely simulate the " water-bag," 

 as to be mistaken for it — though the mistake need not lead to grave 

 results ; indeed, if ruptured the kyst immediately collapses, and can no 

 longer prove a barrier to the expulsion of the foetus. If the kyst is
