Unless in the case of an actually aborted coiv 07ie application only is 

 necessary if properly carried out. 



7' he Method of Procedure in Treating Cows. 



1. Boil for five minutes the tube with the funnel inserted into one 

 end, and then apply to the outside of the tube a dressing of salad oil 

 or good lard. 



2. ^^'ash the hands and arms thoroughly in hot water to which a 

 disinfectant has been added. 



3. Place the free end of the piping by means of the hand gently into 

 the womb (or in the case of an in-calf or sterile cow, as far up the vagina 

 as possible without undue force being used) taking care not to injure the 

 lining membranes. During insertion, the curve of the tubing is better 

 turned downwards. 



4. Hold the outer end of the tubing with the funnel about 6 inches 

 above the root of the cow's tail. 



5. Pour the solution of mercuric chloride, as described, gently into 

 the funnel and so thoroughly irrigate the parts. If the fluid does not run 

 fairly freely from the tube the inner end need only be moved gently to 

 and fro to secure a free flow. The intention is to thoroughly irrigate 

 every portion with the solution. 



6. Thoroughly wash down the parts from the root of the tail to the 

 bottom of the udder with some of the same solution at that used for 

 irrigating. 



7. Release the animal immediately after irrigation so that excess of 

 fluid may not be retained. 



TJie Method of Procedure in Treating a Bull. 



Place the animal in a crush-pen or otherwise secure him in such manner 

 that he may be readily handled without danger. Then grasp the prepuce 

 (or sheath) by the left hand and pass the nozzle of the syringe inside the 

 sheath, afterwards holding it in position with the same hand, then with 

 the right hand pump into the sheath a quantity of the solution, sufficient 

 to thoroughly irrigate the parts. 



Note. — Be certain that the whole of the pellet is thoroughly dissolved 

 before using the solution as any undissolved particle lodging in the lining 

 membrane of the vagina or womb would cause intense irritation. 



Caution. — In connexion with this treatment it is necessary to re- 

 member that 7nercuric chloride is a highly poisonous drug if swallowed, 

 and therefore every care should be exercised in order to prevent accidents.
