SYMPTOMS IN ACUTE TYPE 173 



sick animal becomes more and more typical and the case easier to 

 diagnose. There is a rapid loss of flesh, and the hog becomes very 

 thin, gaunted, and weak. The weakness is especially to be seen 

 when you try to arouse the animal. He is so weak that it is almost 

 impossible for him to rise, and when he does get on his feet he is 

 hardly able to stand. The position in which a cholera animal 

 stands is a very familiar one to those who have seen many cases 

 of the disease. 



The hog sick with cholera stands with his head down, the ears 

 drooped, and the eyes closed, due to both the swelling of the 

 eyelids and the sticking together of the hds from the sticky dis- 

 charge that results from the inflammation of the lids. The back 

 is arched up and the hind legs drawn further forward than they are 

 held in the healthy animal. The flanks are drawn up and give the 

 animal a very gaunted appearance. The hind legs are not only 

 placed further forward under the belly than in the case of a healthy 

 hog, but the animal also very frequently stands with the hind feet 

 crossed, and one foot may be resting upon the other. The tail 

 is drooped and hangs practically lifeless. The skin of the animal 

 has a very dirty and somewhat greasy appearance, diie to the fact 

 that in the course of cholera there is a marked increase in the 

 amount of oily secretion given off from the glands of the skin. 



When the animal tries to walk we note again some very typical 

 signs of cholera. Due to the great amount of muscle weakness, it 

 is very difficult for the animal to get along, and, as this weakness is 

 most marked in the hind limbs, there is especially a tendency for 

 the body to swing from side to side in the hind parts. The hind 

 limbs are used with a great deal of effort, and when the hind feet 

 are moved it is common for the animal to get one leg crossed over 

 in front of the other, much as does a drunken man when trying to 

 walk in a straight fine. Difficulty in walking is made more pro- 

 nounced by the fact that the animal is practically bhnd. There 

 is nothing wrong with the sight of the eyes, as far as the seeing 

 apparatus goes, but the lids are so swollen and tightly glued 

 together that it is impossible for the animal to keep the eyes open. 

 On this account the staggering gait of the hog becomes very much 

 worse and we have a walk very much like that seen in blind 

 staggers.
