is made there with a forceps. Two such needles suffice. 

 To prevent tearing, it might be well to place a leather 

 washer between the skin and eye of the needle. The suture 

 stays well, does not tear out and discommodes the animal but 

 little. The above drawing (Fig. 14) explains such a suture. 



Deneubourg's method consists of perforating the labiae 

 with two thin sticks. Each stick has a cross-piece firmly united 

 to it on one end, a detachable sharp point being on the other 

 end. After perforating both labia?, the sharp point is unscrewed 

 and a cross-piece of the same shape as those on the other end 

 is fastened by means of a screw. 



Fig. 15.— Sauberg's Labial Ring. 



The application of this instrument is easy and simple, bat 

 the copper suture is cheaper and can be readily procured. 

 Sauberg constructed a ring, termed " Sauberg's Vaginal Ring.*' 

 It is 8 mm. wide and 2 mm. thick, 17 cm. long, and made of 

 copper. Its blunt part shows near its end a little hook 4 mm. 

 long ; the other and pointed extremity has a little hole of 2 mm. 

 diameter, 2 cm. from its sharp point. Before its introduction 

 the ring is spread out. Now the labia? are perforated at a 

 proper distance from the free border, both ends of the ring 

 are bent toward each other, and the hook is pressed into the 

 little hole and may be flattened with a pair of pincers, practi- 

 cally riveting the two ends.
