146 A STUDY OF DISEASE IX GENERAL. 



their quick action on the digestive system; of these we find oily 

 doses more useful than the Glauber and Epsom salts. Pills or 

 boli so frequently used in the treatment of the horse are unsuit- 

 able for the sheep or ox, and should not be used. The effects of 

 purgative drenches are greatly assisted by the addition of 

 stomachics and stinmlating agents, which by their action on the 

 nervous system give tone to the mucous lining of the stomaclis, 

 especially the maniplies. When bleeding is resorted to the 

 veins under the ear and eye are usually selected for the operation, 

 b\it should a considerable blood letting be desirable opening tbe 

 jugular will be found the quickest and best. The amount of 

 blood to be drawn should not exceed eight ounces. It is useless to 

 take less than one ounce, as the effect of the loss of such a small 

 quantity on the system would be nil. A rough method of 

 bleeding frequently applied is the amputation of the ear or tail. 

 This is, however, a crude method of obtaining the result desired, 

 and inflicts disfigurment on the animal. 



To bleed from the cheek vein stand astride the sheep, 

 pressing its body between the knees, pass the left hand un- 

 der the jaw, drawing the head upwards and backwards slight- 

 ly. When in this position the animal can neither struggle nor 

 escape, then press the fingers of the left hand beneath the angle 

 of the right jaw, just in front of the swallow or gullet. This will 

 stop the circulation of the vein, causing it to enlarge; with the 

 right hand trace the swelled vein in its course over the cheek, 

 and at a point about equidistant from the eye and angle of the 

 mouth insert the lancet, making the incision from below, up- 

 wards, being careful not to cut through the inner side of the vein, 

 but only its outer border. After sufficient blood has been ex- 

 tracted discontinue the pressure caused by the left hand and the 

 bleeding generally will cease. Should it not, however, insert a 

 pin through the lips of the incision and wind some thread round 

 it. It is sometimes advisable to bleed from the saphena vein.
