tion of the mucous membranes. The pulse becomes in¬ 
creased in number, varying from 60 to 80 and even ioo; it 
mav be at first moderate in volume but becomes weak. 
The discharge from the mucous membranes at first is thin 
and acrid, but as the disease advances it becomes more copious 
and thicker. 
In the condition that is known as pink eye we have tie 
discolored pink condition of the mucous membianes lining 
the nasal and buccal cavities and the eyelids, tumefaction of 
the limbs and eyelids, great stupor, and the animal very weak. 
The fever may run up as high as 105° F. or 106° F., and 
generally lasts from three to four days. 
At the end of this time, if the disease runs a favorable 
course, the fever begins to abate, the appetite returns, the 
various organs take on their natural functions, the pulse falls 
in number and becomes stronger, and we have the animal left 
convalescent in a weakened condition. 
Death in these cases may be the result of an excessive fever 
with failure of the heart’s action, asphyxia from a rapid con¬ 
gestion of the lungs, or from the poisonous effect of the mor¬ 
bid matter due to disintegration of the blood corpuscles. 
The complications, as we have before mentioned, are gener¬ 
ally of an inflammatory nature. As a result of the primary 
lesion we have a congestion of the various tissues. 
This, along with a distended state of the blood vessels, a 
weak heart action and an improper aeration of the blood, is 
very prone to be followed by an inflammation, due to the 
slightest irritating cause. 
During some outbreaks we have the majority of cases 
complicated with an inflammatory condition of the lungs , in 
others we have the complications arising in the bowels or 
liver. Why this should be we cannot determine, unless it is 
that local climatic changes or atmospheric influences may be 
the exciting cause of these local lesions, the animal becoming 
more predisposed due to the pre-existing disease. 
To enumerate the systems of the various complications 
would be to go into those of pneumonia, pleurisy, enteritis, 
etc., which I do not think would throw any light on our sub-
