FOURTH INTERNATIONAL VETERINARY CONGRESS. 
2d.—The sanitary veterinary service must employ the great¬ 
est possible number of veterinarians. To do this efficaciously and 
economically, it is necessary to establish two degrees or classes of 
attaches. The first possessing a more local character, and respon¬ 
sible less to the State than to the municipal and local authorities, 
and embracing, among its duties, the inspection of fairs and mar¬ 
kets of animals, and of meats for butchery and ^abattoirs; the 
control of the rendering places; the inspection of breeding 
animals; the inspection or direction of mutual insurance compa¬ 
nies against the mortality of cattle; the revision of the census of 
domestic animals, &c. The other, wider in its range, comprising 
the State service, and capable of extension into an international 
corps, being responsible specially for the repression aud preven¬ 
tion of contagious diseases and epizootics, as well as having the 
control of the various local bodies. 
3d.—Between the various States which, by a regular repres¬ 
sive and preventive service, may furnish guarantees of a good 
veterinary sanitary police, a convention shall be established, hav¬ 
ing for its objects: 1st—To advise other States with as little de¬ 
lay as possible, of the appearance of typhus, pleuro-pneumonia, 
foot and mouth disease, small-pox, disease of the coit, (dourine), 
glanders or farcy, scabies in sheep. 2d—To publish a periodical 
sanitary bulletin upon these diseases, their extent, progress and ter¬ 
mination ; which documents shall be also inserted in the interna¬ 
tional bulletin, if deemed advisable. 3d—To combat these dis¬ 
eases by measures of sanitary police which shall have been dis¬ 
cussed and adopted as most advisable. 4th—To deliver to ani¬ 
mals or herds traveling in or out of the territory, certificates of 
origin and of health, having only a guaranteed administrative 
, value. 5th—To contribute to the publication of an international 
sanitary veterinary bulletin.
