of the ancient Greeks and Romans, this disease was only observed 
in man in the beginning of the present century. Then it was first 
recognized by Waldinger, of Vienna, and as attention was 
attracted to the subject, his discovery was soon amply confirmed 
from every side. What frightful sufferings and horrible deaths 
had resulted, at all times and in every part of the civilized world, 
before the discovery that man owed this disease to the domestic 
animals, can never be revealed, but from the number of cases re¬ 
ported on all sides, as soon as Waldinger’s discovery became gen¬ 
erally known, a very high mortality can be safely inferred. Here 
again we have a terrible example of the loss sustained by the dis- 
association of human and veterinary medicine. The criminal 
negligence of our State Legislatures to enact laws forbidding the 
use or exposure of animals suffering from this and other fatal 
disorders, contagious to man, may be in part charged on the 
apathy of the medical profession on the subject. The natural 
result has followed; many of our large cities swarm with glan- 
dered horses, which are habitually sent to the country for treat¬ 
ment or change of air, and severe losses are entailed in manv 
localities. What is more to our present purpose, human victims 
are not unknown, one such having just come from under my 
notice, because the attending physicians honestly acknowledged 
that they knew little or nothing of the malady. 
Tuberculosis .—Modern research, mainly in the hands of vet¬ 
erinarians, has established the fact that tubercular consumption is 
a specific and communicable disease, conveyable from animal to 
animal not alone by inoculation, but by feeding upon the fresh 
and even cooked products of the disease. Here again is a subject 
which has proved a battle-field for centuries for the medical men, 
has been definitely settled by a reference to comparative pathol¬ 
ogy, and by instituting a series of observations and experiments 
on the domestic animals. The importance of this discovery of 
the communicability of tubercle to animals and man, cannot be 
overestimated, and speaks with trumpet-tongue of the value of 
comparative pathology to the physician and veterinarian.
