iuutfly. NNIk'ii this is done there is greater certainly of each getting the 

 proper dose and the danger of overdosing is avoided. In the case of 

 young pigs we can talie advantage of the fact that some drugs are ex- 

 creted in the milli, and administer the drug to tlie mother. 



Drenching a hog Is not ditficult if quietly and easily managed. A large 

 herd can be drenched quite rapidly if driven into a small pen, as the hogs 

 will III" in such close quarters that they can not get away. To secure 

 the hog while drenching it, a noose of sash cord or small rope can be 

 placed around the upper jaw well back toward the angle of the mouth, 

 and the medicine administered with a metallic dose syringe. Sometimes 

 when the dose is bulky and the hog hard to hold, it is necessary to ele- 

 vMtc the head and raise the fore feet off the ground. For this purpose 

 a pulley and a rope wire stretcher is recommended. It should be hung 

 in some convenient place in the pen and the animal secured in the usual 

 AAay by placing a noose over the upper jaw. The rope is then thrown 

 over the hook in the lower pulley and the hog drawn up until it is almost 

 off its feet. The drench must not be administered until the hog is quiet 

 and well under control, as there is danger of the medicine getting into 

 the air passages and doing harm. If there is danger of the hogs getting 

 mixed in the operation, as soon as one is drenched it can be marked with 

 paint. 



Drugs when soluble are best given in water or milk; when insoluble, 

 in syrup or oil. Instead of a syringe a long-necked bottle or a funnel 

 with rubber tubing and an iron nozzle can be used. 



By Injecting Into the Tissues Beneath the Skin.— This method of ad- 

 ministration is suitable when the drug is non-irritating, the dose small 

 and when prompt, energetic effects are required. The needle and hypo- 

 dermic syringe should be sterile, and the place of injection washed with 

 an antiseptic wash in order to prevent the formation of an abscess. The 

 point of injection should be where the skin is thin, as the flank, belly, 

 ear, or inside the thigh. The needle is introduced through the skin and 

 the medicine injected beqeath it by slowly pushing the piston. In the 

 case of fat hogs the injection should go into the muscular tissue; other- 

 wise it will not be absorbed promptly. 



By "Way of the Air Passages and Lungs.— This method of administra 

 tion is practiced but little, and usually for a local effect on the respiratory 

 organs only. The hog or hogs are put into a tight inclosure and allowed 

 to inhale the vapors of the drug. Drugs suitable for this purpose are tur- 

 pentine, creolin, eucalyptol, sulphur, etc. Turpentine is the one most 

 used, arui is easily disseminated by pouring on hot water or by putting a 

 couple ounces on hot bricks. Care must_ be exercised when treating hogs 

 in this way, as they may suffer from lack of air. 



By Way of the Rectum.— Enemas or clysters are usually given for a 

 local effect on the rectum or to accelerate the action of a purgative. To 

 administer an enema a fountain syringe is best. The nozzle of the
