the human skin will bear. A flannel cloth should be 

 dipped into the castor oil and spread over the sow's udder, 

 after which hot packs may be placed over the flannel. If 

 the pigs are alive and healthy, they will prevent the 

 spread of the trouble to other parts, and only such portions 

 as are already hardened need be given attention. 



PARALYSIS 



Young pigs in high condition, and receiving but little 

 exercise, are sometimes troubled with the loss of the use 

 of the hind legs. Several causes may be responsible, but 

 relief may usually be secured by compelling the pigs to 

 exercise, and feeding them a ration containing plenty of 

 bone-forming material, as might be obtained by adding a 

 little steamed bone-meal to their ration. One form of 

 the paralysis which does not respond readily to such treat- 

 ment is due to a pressure on the spinal cord caused by 

 the dislocation of vertebrae, or by the inflammation of 

 membranes surrounding the cord. In older hogs, espe- 

 cially in pregnant sows, partial paralysis of the hind 

 quarters sometimes occurs, and is usually fatal. Little 

 can be done except to remove the animal from the others, 

 so that further injuries will not be inflicted. The bowels 

 should be loose, and if necessary a soapsuds enema given, 

 or a dose of salts or calomel, and the animal kept on a 

 nutritious diet. Occasionally, animals so affected will 

 recover after farrowing, although of course it is impossible 

 for a sow in such a condition to give birth to vigorous pigs, 

 or to raise them herself. 



WORMS 



The worms which cause the most frequent trouble in 

 pigs are the round intestinal worms, which inhabit the
