 a marked conjunctivitis, with swelling of the eyelids, sensitiveness to light, 

 and a watery discharge from one or both eyes. The mucous membranes of 

 the mouth become inflamed (stomatitis), ulcers form, and the animal slobbers 

 and refuses to eat. The advanced cases are frequently accompanied by emacia- 

 tion. The tongue is usually affected, and the inflammation may extend through- 

 out the entire digestive tract. The functions of the liver may be disturbed, 

 and a yellowish (jaundice) coloration of the tissues follows. In such cases 

 symptoms of colic are not uncommon, and the respiratory tract may become 

 involved and pneumonia develop. Some observers in other countries have 

 noticed marked nervous symptoms, such as excitement, convulsive movements, 

 staggering gait, and paralysis of the throat, with inability to swallow, the 

 paralysis at times becoming generalized, the animal getting down and being 

 unable to rise. In the cases observed in this state, the nervous symptoms, 

 except the general depression, were not very noticeable. 



"The outcome of the disease depends upon the location and extent of 

 the lesions upon the horse or mule affected. If they are situated on the ex- 

 terior the animal will readily recover as soon as removed from the alsike 

 pasture. If the vital organs are involved, such as the brain, lungs and liver, 

 the disease may readily produce death. Among those cases occuring in this 

 State, not a single fatality has been heard of at the Station. But even though 

 the death rate is small where the ordinary precautions are taken, the disease
