 sunken, and the animal grows gradually weaker. 



These worms seem to develop in hogs that are neglected

 They will not injure them, and will remove any worms 

 that may be present in even apparently healthy animals. 



Every precaution should be used to prevent diseases, and

These are usually termed diseases, but are not properly

 which they cause, still further debilitate them, and effectu-

 swept out, and fresh straw provided. 



If this is done, and the hogs will feed, there will be lit- 

 tle need of remedies.
