TUBERCULOSIS.* 
By M. Arloing, Director of the Lyons Veterinary College. 
I.—Tuberculosis considered from the point of view 
of Sanitary Police. 
For some time yet there will be discussion regarding the 
heredity of tuberculosis; one may ask whether the subjects 
descended from tuberculous parents are born tuberculised or 
more tuberculisable than others ; but it is no longer possible 
to doubt the dangers to which tuberculous animals expose 
their neighbors and their progeny. Such animals discharge 
virus by the respiratory and digestive passages, and by the 
mammary secretion. This virus can infect healthy subjects 
by its introduction into their digestive apparatus with food or 
drink, or into their respiratory apparatus with the atmospheric 
air. 
Experiments, several times repeated, and whose authors, 
known to all, merit our confidence, have placed these facts 
beyond all dispute. 
Hence it is logical to take measures to oppose the propa¬ 
gation of tuberculosis by the tuberculous. The first is to 
class this malady among those which in every country are 
combated by statutes of sanitar}^ police. 
This measure figured under No. 3 among the resolutions 
presented by M. Lydtin to the International Congress at 
Brussels. 
The Congress, being pressed for time, did not examine it. 
The members were more concerned with the relationship of 
tuberculosis to the alimentary hygiene of man than with con¬ 
tagion from animal to animal, and, by a deviation not un¬ 
common in minds pressed and absorbed by a particular point 
of view, they did not perceive that measures concerning 
alimentary hygiene ought to be the corailary and not the 
premises of measures regarding contagion. 
The question accordingly remained to be considered, and
