Nevertheless, cases have occurred in which courts 
have seen fit to review and reverse the decision of 
health authorities relative to infectious diseases 
in animals.?! 
Inasmuch as infectious diseases are the result 
of the action of specific germs, either bacterial or 
protozoal, where those germs have been definitely 
identified by microscopic examination, the sure 
method of diagnosis is by such examination. It 
has therefore been held that a city has, under its 
general powers, the authority to appoint a bac- 
teriologist; and that such office or employment is 
not an interference with the work of the regular 
health official, but an aid in this work.*? While, 
then, a court may not generally interfere with the 
diagnosis of an official veterinarian, it might very 
properly set aside a diagnosis which was evidently 
not made in accord with the present state of 
scientific knowledge. The cause of glanders is 
the Bacillus mallet, which is well known. It is 
not unlikely that where a veterinarian has neg- 
lected to verify his diagnosis by means of a bac- 
terial examination or blood test the court might 
properly question his diagnosis. If, therefore, 
the veterinarian orders a horse killed for that dis- 
ease he should make and preserve microscopic 
slides showing the Bacillus mallei taken from that
