Dr. Paquin also tries to point out weak spots in the conclusion of 
Dr. Smith that Texas fever is a disease of the nature of malaria. 
One of his points is that malaria is not transmissible from one 
point of the country to another, while Texas fever is. Now, I do 
not think any conclusion should he reached from two facts of that 
nature. In the first place, a bacterial disease of one kind may be 
carried to another part of the country and spread among animals 
of the same species, while another bacterial disease may be car¬ 
ried with greater difficulty, if at all, so that one disease may be 
carried and another closely allied might not be carried. And we 
must consider the fact that there is a great difference in the ex¬ 
posure of people as with cattle. We can expose northern cattle 
to southern cattle if there is simply a little difference between 
them, and in a great majority of cases they do not take Texas 
fever. People are exposed to each other in somewhat the same 
way. Cattle have another method of contracting infection which 
people do not have. Cattle go upon pastures, and they eat food 
from the ground which has been soiled by the excretions of south¬ 
ern cattle. There is no possibility of people contracting the germ 
in this way. So I think that facts of that kind simply support 
Dr. Smith’s conclusion. He does not claim, and I do not claim 
that the diseases are identical, but that the micro-organisms which 
causes Texas fever are closely allied to those found in malaria. 
Now, just one other point to which I ask your attention for a mo¬ 
ment. Dr. Paquin says Dr. Smith is not certain how the disease 
is conveyed from southern, to northern animals. Dr. Smith states 
this in his report. He says the farmers of the country are certain 
how the disease is transmitted from one animal to the other; that 
they know these germs are, and that they may be, transmitted by 
the manure and by the urine. I doubt if we can accept such 
conclusions as that. How do they know it when those who have 
investigated the subject are not able to tell certainly ? 1 do not 
believe „ any man—I do not believe Dr. Paquin can-get up here 
and say he is sure that the disease is transmitted to southern cat¬ 
tle through the medium of the manure scattered on the pastures. 
I do not believe he can point to any positive evidence where Texas 
fever is spread by means of the urine and manure cast upon the
