THE PROGRESS OF PLEURO-PNEUMONIA IN AUSTRALIA 
AND AMERICA—LEGISLATIVE ENACTMENTS. 
We took occasion a short time since to notice that the 
fatal disease of Cattle, known as pleuro-pneumonia, had made 
its appearance in Australia and also in America. The facts 
connected with its introduction into both these countries so 
completely proved the contagious nature of the malady, that 
we did not hesitate to declare our conviction that, unless the 
most prompt means were forthwith adopted to arrest its pro¬ 
gress, it would gradually extend itself, and cause a fearful 
destruction among bovine animals. 
The intelligence which we have recently received not only 
confirms these opinions, but puts us in possession of the 
measures which the respective governments have had recourse 
to, and which we must designate as being bold and decisive, 
especially on the part of the government of Australia. 
If the Home government had taken up the subject in the 
same spirit on the first appearance of the malady here, doubt¬ 
less we should not now have had to lament the ruinous conse¬ 
quences it has brought upon so many individuals, nor the im¬ 
mense losses which the country, as a whole, has sustained. 
It is right, however, to say that we lacked originally the 
same proof of the disease being contagious which has been 
afforded to our transatlantic and antipodal brethren. The 
malady reached our shores as an ordinary epizootic , and, sin¬ 
gularly enough, only a few months before our free importa¬ 
tion of Continental cattle took place. Had it delayed its 
coming, fewer doubters of its being contagious would at the 
first have been found; and probably some preventive measures 
might then have been adopted by the legislature, as was the 
case on the introduction of the smallpox of sheep. But is this
