the vulva, and carried forward between the hind-legs and underneath 

 the belly in the same manner, two or three transverse narrow straps 

 passing between the two, immediately over the vulvar opening. 



When there is much swelling, a soft cloth doubled several times, or a 

 sponge steeped in cold water, may be placed over the vulva beneath the 

 strapri, though in such a way as not to interfere with micturition or de- 

 fecation. 



Various other trusses for the Mare or Cow have been proposed by 

 veteriiKiry obstetrists, but in principle they are all the same. We 

 need only notice one of these, which has been proposed by Lund, a 

 Danish veterinary surgeon, and which has been greatly lauded by 

 Dieterichs and others for its cheapness, simplicity, and elliciency. The 

 chief part of it is a narrow piece of iron, nine millimetres thick (about 

 one third to three-eighths of an inch), welded at its extremities, and 

 turned into a triangular shape that enables it to include the vulva, while 

 the loops at its three corners allow it to receive cords (Fig. 218). The

base of the triangle, which fits under the tail, is about two to two and 

 a half inches wide, and the sides from five to seven inches long. The 

 loopholes at the angles may be replaced by small hooks to receive the 

 cords. 



This metal plate — which may be of round iron and convex on one 

 side, concave on the other — fits over the vulva and the base of the tail, 

 the apex being below the lower commissure, while the convex side is 

 towards the animal. Cords pass through the loops or around the 

 hooks, one above, another below — as in Fig. 219— and are fastened to a 

 surcingle or collar, or both, like the preceding trusses. Any black- 

 smith can make the plate in a few minutes ; and from what has been 

 said in praise of this cheap and simple method of retaining the uterus, 

 there can be no doubt that it will be found most useful. 



All these trusses are intended for the larger animals, and cannot well 

 be appUed to the smaller creatures, with the exception perhaps of
