CONFERENCE IN BROOKLYN. 
503 
The Chairman stated that invitations had been sent to repre¬ 
sentatives of every Board of Health in the State of New York 
who were said to be familiar with the subject, and opened the 
conference by reading the annual reports of Veterinary Inspector 
Dr. L. McLean, in which he called attention to the continued and 
increasing prevalence of contagious pleuro-pneumonia among the 
milch cows of that city (Brooklyn), and stated that, in his opinion, 
there was not another city in the Union in which the milk-pro¬ 
ducing stock was so affected with contagious pleuro-pneumonia. 
Speaking of the two remedial measures of prevention, viz., the 
slaughtering process and inoculation, he strongly advocated the 
latter remedy, so far as the City of Brooklyn was concerned. He 
mentioned several cases in which he had inoculated cows in stables 
in which pleuro-pneumonia was known to exist; and in others, 
where it had broken out, with the result, that those which he had 
inoculated had not been affected with the disease. He said, 
while he thus advocated the adoption of inoculation, in order to 
meet the local conditions in recently invaded districts and isolated 
cases, its extirpation could be more radically effected by the 
slaughtering process carried out in its entirety. 
The Chairman having called for an expression of the opinions 
of the gentlemen present, upon the subject: 
.Professor J. Law said he trusted that, by an interchanging of 
ideas, they would be led to some tangible result. He conceded 
that Dr. McLean’s views were right, whenever they could do no 
better. He had held, for many years, that an inoculated animal 
is protected just as a person is protected from smallpox. He 
gave the views of inoculation for pleuro-pneumonia, as expressed 
at the Congress of Veterinary Surgeons held last year in Brussels, 
The disease bore a great resemblance, in one respect, to glanders 
in horses, and to consumption in men and animals. Glanders 
and tuberculosis would not affect to the same extent as contagious 
pleuro-pneumonia and the lung disease, but tliat made the lung 
disease all the more dangerous, because it was very liable to ap¬ 
pear in a form not readily recognized. In dealing with these 
matters, simple inoculation or temporary measures were not suf¬ 
ficient. There was a necessity for continuous restraint in every
