FOURTH INTERNATIONAL VETERINARY CONGRESS. 
for the high honor conferred upon him in calling him to the 
Presidency of the Congress,'and expressing his regret that he 
was prevented by sickness from participating in the meetings. 
The Secretary also read letters from several members of the 
Congress, offering apologies for their inability to be present. 
The bureau had also two communications from Mr. Lindquist 
(Stockholm), one relating to the organization of the veterinary 
service in Sweden; the other to the prophylactic measures 
against epizootics. 
On motion of Mr. Lindquist, the papers were approved, and 
their publication in the bulletin of the Congress was ordered. 
The minutes of the last meeting were read and adopted, 
with the suppression of a sentence of Mr. Cagny, which consti¬ 
tuted a repetition. 
The Secretary suggested that he believed the Congress might 
suspend its work on the following Friday at an earlier hour than 
usual, and appropriate the time to a trip to Antwerp. Facilities 
for the excursion at reduced rates of travel will also be offered to 
the members of the Congress on the following Sunday, to Ostend, 
Blankenburghe, Burges or Gaud. 
The President:—The question of to-day is pleuro-pneumonia. 
Mr. Degive, reporter on the subject, has the floor. 
Mr. Degive first considered the differential diagnosis of conta¬ 
gious pleuro-pneumonia, referring to the essential parts of his re¬ 
port. 
Mr. Tjsseraud thought that the symptoms described by the re¬ 
porter are insufficient. He gave a description of the symptomat¬ 
ology of the disease, and presented his views upon the nature of 
the affection ; he rejected the spontaneous generation of the dis¬ 
ease, as well as that of the transformation of germs, and proposed 
a namendment in conformity with his views. 
Mr. Putz objected to the spontaneous development. 
Mr. Leblanc agreed with Mr. Degive upon the question of spon¬ 
taneity; according to his observations it is rare and exceptional. 
From an anatomical point of view he cannot establish any differ¬ 
ence between contagious pleuro-pneumonia and sporadic pneumo¬ 
nia. It can only be distinguished by its contagious character.
