and produce sudden death due to suffocation. The 

 worms may set up an inflammation of the lining mem- 

 branes of the lungs, which is sometimes taken for S\vine

 close the windows and doors and any large cracks, then 

 compel the hogs to inhale steam from the following 

 mixture : Turpentine, eight ounces ; Pine Tar, one pint ; 

 Water, two gallons. Place in tin receptacle in center of 

 the shed and heat the above solution by adding hot 

 bricks or stones to the mixture occasionally. Compel 

 them to inhale this steam for at least thirty minutes 

 twice a day. Feed wholesome food to which add hog

 strong, vigorous hog may have worms, but it retains its 

 vitality so long as it is well fed.

When treating this disease, the real aim must be to

 is better done with some good disinfectant, one part to
