PLEURO-PNEUMONIA. 
There have been several fresh outbreaks of the disease in 
different parts of the country, and in some rather a serious 
extension of it has taken place. As might have been 
expected, disputes have arisen between non-professional 
inspectors and veterinary surgeons as to animals being the 
subjects of the disease or not; and in several such cases we 
have been asked to examine specimens of diseased lungs, 
that we might confirm the professional opinion of the exist¬ 
ence of the malady. This is an evil which has been created 
by the local authority, and it is no small one for the country 
to have to sustain in these days of the rapid spread of infec¬ 
tious diseases among cattle. 
In a few instances inoculation has seemed to afford some pro¬ 
tection against infection, but in many others the disease has 
ceased after attacking two or three animals of a herd, even 
when no such precaution has been taken. The peculiarity 
of pleuro-pneumonia is its long period of incubation, which 
gives ample time, on the discovery of an outbreak, for the 
separation of the sick or suspected from the healthy, and the 
slaughter of those which are ready for the butcher, thus 
lessening the number of susceptible subjects. 
In many of the London dairies the disease maintains its 
usual rate of prevalence, and there is good reason to believe 
that the facilities which now exist for the removal of cattle 
out of the metropolis have had to do with some of the recent 
outbreaks of pleuro-pneumonia in country districts. 
In the Netherlands the disease has considerably decreased. 
SMALLPOX OF SHEEP. 
This disease is again on the increase in several of the 
North German provinces which lie on the shores of the 
Baltic. From Pomerania we learn that many cases have 
recently occurred ; but under the existing “ Order ” with 
regard to German sheep and goats we shall in all probability 
he protected against injury arising to our flocks, even if 
sheep-pox should he again introduced.
