ON llABIES.

has been attacked by spontaneous rabies cannot transmit the 
disease to others. Hertwig, of Berlin, has instituted various ex¬ 
periments on this interesting subject, which prove that there is 
little or no foundation for this opinion. We should not, therefore, 
be justified in neglecting the confinement of every animal that is 
suspected of having been bitten by a rabid dog. 
In the department of the Seine, the commissaries of police 
bring every dog that is suspected to have been bitten to the 
school at Alfort, where he is placed in a kennel devoted to this 
purpose, and carefully watched. It is the same at Lyons and 
Toulouse, and the neighbourhood of these two cities : but in every 
other situation the dog ought to be placed under lock and key, 
and secured by a chain, and carefully watched, and destroyed 
the moment that the peculiar howl is heard which we have de¬ 
scribed as the avant-courier of the appearance of rabies. 
The duration of the confinement should not be less than six¬ 
teen days ; and after that lapse of time, and during the two fol¬ 
lowing months, the dog should not be suffered to range at liberty 
without being carefully muzzled. 
D. The conjinement of horses and cattle ,—Horses and beasts, 
bitten by mad dogs, should not be suffered to range on any com¬ 
mon pasturage, or to drink from the open pool. They should 
be kept in the stable, or in places at a distance from other ani¬ 
mals, and appropriated to themselves alone. 
Sorel Baudieu has related two facts which render it probable 
that the saliva of rabid cattle and sheep may be deposited on the 
herbage, and browsed upon by animals of the same species, 
and the disease thus communicated. Although this supposition 
is controverted by Hertwig, who caused twenty-two dogs to swal¬ 
low the saliva procured from rabid dogs, and not one of them 
was infected, yet, if these sus|)ected or infected animals are kept, 
they should be fastened in places altogether distinct from those 
to which others have access. 
Horses, asses, and mules, may be worked during this period of 
sequestration, but they should be muzzled, in order to prevent 
possible accidents. Their period of sequestration or confinement 
should not be less than two months. During that time, they 
ought not to be exposed in any markets or public places, nor 
should they be sold to the butcher until three months have 
passed. Every one neglecting these precautionary measures 
should be fined one hundred francs at least.
