TEXAS OR SOUTHERN CATTLE FEVER.

. After the above symptoms are noted, the blood becomes very 
thin and watery, which can be easily detected by making small 
incisions in the skin ; bloody urine is passed from the bladder. 
In addition to the above, ticks are generally present, located 
usually on the inside or back part of the thighs towards the 
tail, the skin being thin in those parts. They are also found on 
other parts of the body. 
The bloody urine is not due to discharge of blood from the 
kidneys, but to a filtration of the coloring matter of broken- 
down red corpuscles. Temperature continues high until the 
disease terminates fatally or in recovery, when in either case it 
may fall below normal, but more apt to in case of a fatal ter¬ 
mination. The evening temperature is the highest for three or 
four days, then the temperature will stay high night and morning 
until end of the fever—respiration 60 to 100, pulse 90 to 120 and 
weak. If case terminates fatally, or in recovery, the respiration 
often falls below normal, after the high fever has subsided. 
There are three or four leading features, which enable a per¬ 
son to make a correct diagnosis—the presence of ticks, bloody 
urine, watery blood and high temperature. In addition to the 
above the examination of the blood under the microscope, to 
find the microparasite in the red corpuscles, is a valuable aid, 
but as this is not practicable to the general practitioner, I will 
not go into details. Duration of disease in summer months is 
from six to twelve days. 
Post Mortem .—The outward appearance of the skin does not 
show anything, except the presence of ticks. 
The fat and subcutaneous tissue are often a light lemon color. 
Heart is sometimes spotted with petechia in advanced stages. 
Spleen very much enlarged; some that I have weighed 
going up to 8 % lbs., while the normal spleen is about 2 lbs.— 
when cut into it presents a dark brownish red color. The 
peculiar enlargement is due to engorgement with red blood 
corpuscles. 
Bile in gall bladder is changed considerably, being thick, of 
a yellowish brown color, and a great deal of it.
