Paracentesis Abdomenis is the same operation, to empty the belly in 

 peritonitis. Make the incision in the center line of the belly just back of 

 the navel. Use the same trochar, but do not insert it deeper than two 

 inches. In either of these operations, when the instrument is withdrawn 

 the hole will close without any aid, 



n. Tracheotomy. 



This is the insertion of a tube in the windpipe, in case of threatened 

 suffocation. It is identical with the same operation on the horse, de- 

 scribed on page 558. 



m. Tapping the Rmnen (Patmch) for Hoven. 



Insert the trochar, which may be a large one (f of an inch in diame- 

 ter), in the center of a triangle made by the last rib, the anterior point 

 of the hip and the ends of the transverse processes of the lumbar spines 

 on the left side. Point it downward and inward obliquely, and it will 

 pass directly into the paunch, which grows to the left side only, and only 

 in this vicinity. Pull out the trochar, and the gas will escape through 

 the cannula. (See the article, with cuts, on Hoven.) 

 IV. Rumenotomy. 



This is an operation to empty the paunch in case of engorgement, when 

 a passage cannot be effected m the regular way. Clip off the hair from 

 the triangle described in the last article, on the left side, (see cuts on 

 pages 862 and 863) ; and make an opening, running up and down, large 

 enough to insert the hand ; open first the skin, next the muscles, then the 

 wall of the paunch. Insert a towel, and arrange it to cover the lower 

 edge of the wound, to keep the latter clean. Then empty the paunch 

 with the hand. When nearly empty, pour in recipe No. 26, wash the 

 wound, and sew it up with cat-gut sutures. First sew the paunch, leav- 

 ing the ends hanging inside ; then draw the muscles together, the ends of 

 the ligatures hanging outside ; then sew up the skin. Dress the whole 

 with lotion No. 9, keeping the parts wet with it nearly all the time. 



V. Castration. 

 This may be done to calves by laying them down on their backs, open- 

 ing the scrotum and cutting through the tunics to the testicle, letting it 

 out, when the tunics may be cut from their attachment at the end of the 

 testicle, and the testicle pulled out, tearing away the spermatic cord. 

 Pour a little cold water into the scrotum, and let the calf u}). Old bulls 

 may be castrated standing. Make a separate opening for each testicle, 

 and let the testicle out of the tunics ; cut off the cord with the ecraseur 

 well up towards the body ; if no ecraseur is procurable, apply clamps, 

 •«bich may be removed after two days.
