gums. These ulcers are irregular, ragged, and bleed almost con 

 stantly. Petechial hemorrhages may be found in the skin, and in 

 the mucous and serous membranes. The liver and kidneys may 

 show fatty changes. The spleen and lymph-nodes are enlarged. 



Symptoms. — Progressive emaciation, dullness, diminished appetite, 

 increased thirst, and a dislike to move, characterize scurvy. On 

 inspection, gum ulcerations will be observed, and cutaneous hemor- 

 rhages may also be visible. The disease is rather serious unless the 

 cases are observed early. 



Teeth 



Defects of the teeth occur in swine and are in some cases respon 

 sible for failure of development or loss of condition. Irregularities 

 of the teeth frequently cause injury to the tongue or buccal mucous 

 membrane. 



Such disturbances are manifested by quidding of feed, salivation 

 and unthriftiness. The method of producing relief in such cases 

 will depend upon the nature of the irregularity. It may be neces- 

 sary to extract one or more teeth, which is ordinarily not difficult 

 to do if the hog is properly restrained. Foreign bodies may be 

 lodged and become wedged between the teeth and produce a chain 

 of symptoms as above enumerated. Foreign bodies can usually be 

 removed with little difficulty by means of dressing forceps. 



The canine teeth, or tushes, frequently become very long, espe- 

 cially in old boars, and they are sometimes used as a means of 

 oifense. They can usually be cut off by means of bone forceps o;- 

 molar cutters, the animal being properly restrained. 



Little pigs frequently tight each other, producing scratches and 

 injuries to the skin from their small sharp teeth. These injuries 

 are of no consequence, unless they become infected. 



Parotid Glands 

 Injuries of the parotid glands may occur. The most frequent 

 injuries are inflicted by dogs or they result from fighting. The care- 

 less use of stanchions or pinchers in restraining swine may produce 

 injuries of these glands. 



PAROTITIS 



Parotitis is rare in swine. This condition may be the sequel of 

 an injury or it may occur as a result of extension of infection from 

 the buccal mucosa. Inflammation of the parotid glands is mani- 

 fested by swelling below the ear near the angle of the jaw. There
