INVERSION OF THE VAGINA DURING PREGNANCY 99 



Van Leeuwen (Holland) describes a modification for 

 the " labial ringing " : "I first hobble the animal's hind legs 

 and place an assistant on each side of the cow to prevent her 

 from moving about. Now I perforate both labise of the vulva 

 with an ordinary seton needle and pull a piece of rubber tubing 

 through the holes. The latter is done by attaching the gutta- 

 percha tube to the seton needle and thus pulling it through the 

 wounds, or by grasping the tubing with an artery forceps 

 pushed through the wound. After the tube has perforated 

 both labia?, a figure 8 knot, close to the vulva but still allow- 

 ing a little vantage, is made. To further secure both knots 

 they may be tied by string. 



Two such sutures, requiring about 1 m. guttapercha tubing, 

 are sufficient. The great advantage of this method lies in the 

 point that such a suture may remain for months, even years, 

 without tearing out, due to the softness and elasticity of its 

 material. 



Wollenmann, at Eschenbach, constructed an apparatus 

 consisting of a sharp needle, at the blunt end of which a little 

 hook is found. The needle is passed through the labise ; into 

 the hook at its blunt end he hangs a brass ribbon which has an 

 eye at the one end and a little hook at the opposite end. The 

 brass ribbon is pulled through the lips by means of the needle, 

 and by bending its two ends toward each other it is fastened by 

 putting the little hook into the eye. 



Should we see during reposition that the vaginal mucous 

 membrane is injured or shows superficial necrosis, on account 

 of prolonged exposure to the air, treatment is imperative. For 

 this purpose the vagina is irrigated twice daily for three to five 

 minutes with a warm 2 per cent, alum solution. The solution 

 must not be cold, as it may induce the animal to strain. 



3.— Paralysis of Gestation, Paraplegia ante Partum. 



This name comprises many disturbances and derangements 

 of the most varied kind, so that we cannot speak of a definite 

 clinical entity. It is given this name, as the closest examina- 

 tion does not result in an exact diagnosis.
