nent authority on tuberculosis in the world squarely antagonis¬ 
tic to their theory, they wage murderous warfare on the herds of 
of the husbandman. It is against this outrage that The Gazette 
has persistently protested. It raises no. objection to a study of 
this disease at public expense ; it has stoutly opposed the ex¬ 
perimentation on private property which has characterized the 
tuberculin crusade and has demanded that it cease until more 
light is shed on the subject. 
Now a great light has shined. Truly enough “ the sanitary 
systems of the world have been shaken to the very roots. The 
word revolution but faintly expresses what the discovery will 
precipitate.” The supposed menace to public health from tu¬ 
berculous cattle is wholly eliminated by Dr. Koch. The ques¬ 
tion then becomes merely an economic one, concerning only the 
breeders and owners of cattle. If a man believes he has the 
disease in his herd he can use the tuberculin test if he wishes. 
Valuable breeding animals that may react can be isolated and 
bred from. Sanitary conditions can be instituted, for in the 
language of a French scientist at the London congress, “ a sani¬ 
tary house is anti-tubercular.” 
But the reign of the pole-axe in the hands of the public of¬ 
ficial is doomed.

4. Periotomy is the resection of a part of the conjunctiva 
around the cornea Although it is an operation that is seldom 
attempted, it is a procedure that should be selected when no 
other surgical interference or palliative treatment will improve 
the existing condition, which may be considered an indication 
for the operation. In veterinary practice we would not recom¬ 
mend the operation, excepting when no other treatment can be 
used instead, and when unsatisfactory results would not lessen 
the usefulness of the patient. Undesirable sequelae common to 
the operation cannot be obviated in animals as in man, even if 
the greatest care is taken to do the operation aseptically ; the 
danger of subsequent infection is much greater than in human
