250 HOG DISEASE. 



an epizootic or prevalent form, and that the more 

 diseased or dead ones there are, the more decided 

 this infectious or epizootic influence becomes. It 

 is always safe, if not imperative, to keep well hogs 

 away from the sick, dying, or dead ones. 



SYMPTOMS. The symptoms are not the same from 

 year to year, nor even during the same epizooty, but 

 are varied by the prevalent genus of the disease and 

 mode of its localization upon the different organs. 

 The more early manifestations are : The eyes look 

 dull and deep set in the head ; the hair seems to rise 

 or rough up j the inner corner of the eye is gumed 

 up ; the animal seems to be dull and weak ; he does 

 not run to his feed, but comes slowly or not at all ; 

 he eats as though he had no appetite ; holds the nose 

 down close to the ground, or it is drawn to one side; 

 he does not lie down with the other swine, but mopes 

 about by himself, or lies in the sun, instead of the 

 shade ; and as the disease progresses he refuses his 

 food altogether. He lies down a good deal, has an 

 unsteady gait, and shows a tendency to bury his 

 head, or even his whole body in the litter. This first 

 or forming stage may continue from a few hours to a 

 day or more, when the condition presents a train of 

 symptoms which are varied according to the local za- 

 tion of the disease. 



If it falls up on the brain and spinal cord \ with in- 

 tensity, the pig may give a sudden squeal, and fall 

 down in convulsions and die in a few minutes.
