DISEASES OF CATTLE. 



to. inclose the vulva is formed, the lower commissure being left free 

 for the escape of urine. The two ends of one cord (b, b) pass over 

 the back, and are secured to a strap round the neck or chest. Those 

 of the other cord (c, c) pass between the thighs, and are fastened to 

 the upper part of the band. The loops should be wrapped in cloth, 

 to prevent chafing the parts under the tail. 



For small animals, pessaries of the forms shown 

 in Figs. 1093 and 1094 are sometimes used. These 

 are usually made of rubber. 



Another form of truss, Renault's, is shown in 

 Fig. 1095. This consists of a leather neckrstrap, 

 and a rbpe the size of the little finger, and about 

 thirty feet long. The neck-strap is first put on. 

 The cord is then, doubled in the center, and put 

 across the back, behind the withers, so that each 

 portion may fall behind the shoulders and be passed 

 under the chest, where -they are crossed, the left 

 passing to the right, and the right to the left. Each 

 side is then carried through the neck-strap back 

 over the front of 

 the shoulder, at the 

 top of which both 

 are tied in a sim- 

 ple knot. Ten or 

 twelve inches from 

 this a firmer knot 



is tied, then several others beyond it at equal 

 distances toward the lbins, as far as the root of the tail, where 

 another simple knbt is tied. The branches of the cord then sepa- 

 rate to pass reach side of the vulva, and are again united in a simple 

 knot below the inferior commissure. Each cord is then carried be- 

 tween the hind legs, and brought up and tied over the back to one 

 of the loops there, as shown in the illustration. The simplicity of 

 this truss is its chief recommendation. It can be made easy or 

 tight) as is necessary. 



INFLAMMATION OF THE UTERUS, OB METRITIS. 



This is generally associated With parturition in cases where the 

 labor has been protracted, and where unskillful or rough usage has 

 been : resorted to. It may arise from a cold caught during • labor, 

 from excessive or injudicious vaginal injections, or from external 

 violence.
