places, but is usually restless and will move from 

 one place to another. This condition lasts for a 

 day or two, after which time he becomes more rest- 

 less and may go 30 miles in a day. He will drink 

 water, eat sticks, stones, and bite other dogs, 

 horses, and cattle, less often man. This condition 

 will last from one to four days, and then the dog 

 becomes partly paralyzed, so that he can no longer 

 swallow, or his legs may be affected, so that he will 

 lie in one place, and usually dies after a few days 

 longer. In the dumb form, the animal seeks dark 

 places, is rather restless, the throat and lower jaw 

 become paralyzed, he is unable to swallow or to 

 close his mouth and, therefore, cannot bite. Some- 

 times they will change from one form of symptoms 

 to the other. 



In the horse the symptoms vary somewhat from 

 those in the dog. The horse is restless, usually 

 violent and will kick and bite, oftentimes showing 

 sexual excitement. He may break his teeth on the 

 manger and oftentimes bites his own flesh at the 

 place where he has been bitten by the dog. The 

 symptoms usually develop in from eight to twenty- 

 eight days after the animal is bitten, but may not 

 develop for six months. The disease runs its course 

 in from two to ten days, with a fatal termination. 



There is no treatment for the disease after the 

 symptoms have developed. In case man is bitten 

 he should take the " Pasteur " treatment, which is 

 a preventive, and it should be taken in a very 

 short time after being bitten. After the symptoms 

 begin to show it is too late to take treatment.
