EDITORIAL. 
First on the list came a paper on hog cholera by Dr. Salmon, 
who improved the opportunity to confirm and establish his prior¬ 
ity of claim as discoverer, in respect to the various forms of dis¬ 
ease in swine which veterinarians have for years considered and 
contended to be a single lesion. Dr. S. also gave a statement of 
the adoption of similar views by the European, and lately the 
French pathologists, as the result of their observations of recent 
outbreaks of diseases among swine, more particularly at Marseilles, 
within a recent period. 
Dr. Clement spoke on the subject of the pathological lesions 
of pleuro-pneutnonia-contagiosa and of tuberculosis. He exhib 
ited before the Association a large collection of specimens of 
various kinds, without doubt the most valuable and interesting 
exhibit ever submitted to the inspection of a veterinary meeting. 
Another of the important incidents of the meeting was the 
presentation of a second paper by Dr. Salmon, on a new Subject. 
In a recent number of the Eeview we printed a communication 
from Dr. Gadsden on the subject of “ mediate contagion,” and 
we at the same time suggested the propriety of such a discussion 
of the points presented by Dr. G., by such of our correspondents 
as have sufficiently considered the matter, as would tend to elicit 
the merits of the case and confirm or refute the newly advanced 
theory. Dr. Salmon’s paper contained this answer to Dr. Gads¬ 
den, and to its publication in our present number* we add Dr. 
Law’s contribution on the same subject. We are glad to see our 
suggestion so amply seconded, and trust that these papers will be 
read with attention and profit. 
W E have received from Director Nocard, the General Secretary 
of the Organizing Committee, the circular of the Fifth Nat 
ioual Veterinary Congress, called to meet in Paris during the 
month of September, 1889. 
It is with pleasure that we comply with the request of our es¬ 
teemed friend and colleague by calling the attention of American 
♦After waiting for the Secretary of the Association for several days after the 
meeting, we are obliged to postpone the publication of the paper, as the Secretary 
has failed to send it.
