INFLUENCE OF CLIMATE, ETC., ON THE DISTRIBUTION & CHARACTER OF DISEASE. 6 og 
when we forcibly killed her some months later, she showed little 
constitutional signs of disease. 
In another case, a veterinary officer condemned a horse 
severely affected, shot it in the head at close range with a shot¬ 
gun, saw it roll over and go into its death-struggle when, on 
account af a storm, he turned away. Later the owners helped 
the animal to his feet, fed him liberally, the hole in his head 
healed, and some time later, when the horse had apparently 
i ecovered, the veterinarian found it difficult to persuade the 
owner that his horse was affected with a surely fatal disease and 
must be killed. * * 
I claim that it is not appealing to intelligence to urge the 
destruction of glandered horses upon the ground that it is either 
rapidly or surely fatal, because such assertions are evidently 
incorrect, and horse-owners can see it as well as veterinarians. 
Science is truth, and the prevaling . notions of the course and 
terminations of glanders are not true, and veterinarians are 
largely responsible for it. 
I have been surprised and gratified by the unaminity by 
which those I have asked to aid me in this paper, have, when 
any opinion at all is expressed, granted the possibility of recov¬ 
ery in cases of glanders. 
In bovine pleura-pneumonia we find ample reasons for quar¬ 
antine and slaughter, when only a small percentage of cases re¬ 
sulted fatally and the disease was not communicable to man. 
How much more may we urge slaughter when eventually nearly 
all cases prove fatal and at all times the danger of human infec¬ 
tion confronts us ? 
Tuberculosis is, in many respects, allied closely to glanders 
and its distribution and character are modified by similar influ¬ 
ences. In both diseases the course and duration is indefinite ; 
the bacilli arranging themselves in groups in various tissues and 
organs, become encapsuled and eventually tend to perish there¬ 
in. Both affect largely, both primarily and secondarily, the 
lungs, and both attack preferably the lungs of those individuals 
among susceptible species, other environments ‘ being equal, in
