THE NATURE OF TEXAS CATTLE FEVER. 39
In one case (No. 51) tuberculosis, limited chiefly to the lymphatics,
was discovered at the autopsy. Even in this animal, after three days
of high temperature from Texas fever, the corpuscles still numbered
5,125,000. There could have been no anemia, therefore, in spite of the
tuberculosis.
The destruction of red corpuscles is the essential phenomenon of
Texas fever from which all the various pathological processes take
their origin. A glance at the figures in the appendix will show that
this is a constant occurrence and present in every case in proportion
to the acuteness and severity of the attack. Some illustrations will
demonstrate these statements.

These few examples will suffice to illustrate the rapid disappearance
of red corpuscles from the circulating blood. They are by no means
extreme cases, but stand for the average rate of disappearance in acute
cases. This would be for No. 80 at the rate of about 1,000,000 corpus-
cles per cubic millimeter a day during the last three days; for No. 129
at the rate of 800,000, and for No. 163, 700,000. That this rate of de-
struction is very high becomes evident when we bear in mind that in
No. 80 it represents the loss in twenty-four hours of one-sixth of all the
red corpuscles usually circulating in the body. In the other cases it
represents from one-seventh to one-eighth of the whole number.
In the mild non-fatal type the rate of destruction is lower.
