restrict such introduction of fresh and undiseased cattle into in¬ 
fested stables, yet the laws must be so made and executed that 
the same may be restricted into the narrowest possible limits. 
This would probably be most effectually attained by the State 
refusing to allow any reimbursements for such introduced animals 
whether perishing from the natural course of the disease, or if 
killed by the veterinary police in the execution of the law, 
whether found diseased or not. It is not difficult to decide what 
means or regulations are scientifically indicated for the suppression 
of this disease. The immediate destruction of all infected droves 
and thorough cleaning and disinfection of all their surroundings, 
is the only safe and radical means which offers itself to our con¬ 
sideration ; by this means, and this alone, can we have any hope 
of destroying the unknown infectious elements by which the 
disease is sustained and extended. The very excellent conditions 
existing in Switzerland demonstrate most effectually how valuable 
for the other continental States is the obligatory and exact exe¬ 
cution of regulations of this kind. One hundred years’ experience 
in the canton of Bern, very rich in cattle, lias so emphatically 
proven the trustworthiness of the above assertion, that in the new 
laws for the Swiss confederation the same is made obligatory for 
all. Art. 24 of the “ Laws and Regulations against Animal 
Pests” (1872) contains the following words: “No cattle which 
have been diseased by 'pleuropneumonia can on any account again 
become an article of transport .” 
“ When this disease presents itself in any district, not only 
the diseased but other cattle in the same stable or drove or graz¬ 
ing upon the same land, must be unconditionally killed. Only 
by special permission of, and under the most stringent control of 
the veterinary police authorities may treatment be allowed. 
Animals which have been diseased and withstood the same, and 
are apparently healed, may be at once slaughtered, but cannot 
become an article of transport.” 
The most stringent regulations must exist against adjoining 
lands where the treatment of the disease is allowed, and where 
such animals are again permitted to become im article of trans¬ 
port on apparent recovery.
