TEXAS FEVER 337 
and fatty degenerations are not common, although occasionally 
present in the epithelium of the tubules. The pelvis is often sprinkled 
with ecchymoses. 
The bladder may contain ecchymoses. 
It is important to note that throughout the kidneys, liver and spleen 
pigment may be more or less abundant. 
In the digestive tract the lesions of this disease consist largely of 
congestion of the mucosa especially in lines corresponding to the 
summits of the folds of the mucous membrane. It is more marked 
in the cecum and rectum than in the colon. The cecum and less often 
the rectum contain dry, hard fecal balls. In some cases in the intes- 
tines lesions are not observable. In the older writings much emphasis 
is placed on certain lesions, mostly nodular or abrasions, in the diges- 
tive tract. - Smith has shown, however, that most of these are due to 
animal parasites and have no relation to Texas fever. 
As already stated, Texas fever is a disease of the blood and conse- 
quently it is in this fluid that the most constant morbid changes occur. 
They are characterized by the blood becoming thin and watery with a 
destruction of the red blood corpuscles. In some of the cases the loss 
of corpuscles is rapid and continuous until death or convalescence, 
while in others there is a marked oscillation between destruction and 
regeneration. In some animals the loss is not continuous, but the 
course of the disease is marked by the periods of rapid blood destruc- 
tion and periods of rest, or, as it were, where the blood destruction was 
holding its own. These points are best illustrated from actual cases, 
three of which are taken from the report by Smith and Kilborne.
