staining from employing; for breeding purposes such as were 
visibly the subjects of the malady. Scrofula, however, is not 
unfrequently occult, and consequently breeders of cattle may 
unwittingly use infected animals for procreation. Such prac- 
tice will be sure to prove a fertile source of mischief, to avoid 
which no animal should be selected for breeding purposes whose 
family is known to have been affected with scrofula. 
The removal of the restrictions on the transit of cattle, which 
had been rendered necessary by the existence of the cattle 
plague, early led, as had been anticipated, to a great increase of 
pleuro-pneumonia, mouth-and-foot disease, and other infectious 
•naladies of cattle. So long as the restrictions upon the move- 
ment of animals along public roads to fairs and markets, or even 
by railway, were in force, all infectious and contagious diseases 
were kept in check. The system was eminently protective in 
its influence, and not only was the eradication of the cattle 
plague greatly facilitated by it, but the attacks of pleuro- 
pneumonia, and mouth-and-foot disease, were so much dimi- 
nished as to render these maladies comparatively unimportant. 
With a view to obtain exact information as to the increase 
of pleuro-pneumonia and other infectious diseases a paragraph 
was inserted in the " Veterinarian" as early as February, 
asking the members of the profession to give prompt information, 
not only of outbreaks of these diseases, but of their probable 
cause. Much valuable information was received, and in by far 
the larger majority of cases the occurrence of pleuro-pneumonia 
was clearly traceable to the introduction of newly purchased 
stock, and in not a few instances to the bringing of Irish cattle 
on to the premises. 
The admission of cases of pleuro-pneumonia into the College 
Infirmary gave opportunity for fresh experimental treatment of 
the disease. Among other cases, a valuable Alderney bull, the 
property of Miss Burdett Coutts, was sent to the Infirmary for 
this especial purpose. The agent chiefly relied upon was car- 
bolic acid, but, although it was found to possess an influence 
over the disease much beyond many other remedies, still it failed 
completely in effecting a cure. As a disinfectant, however, in 
cattle sheds where pleuro-pneumonia exists, the free use of 
carbolic acid is to be strongly recommended. 
Advantage has also been taken of the increase of pleuro- 
pneumonia to ascertain whether any specific effect would be 
produced by the direct introduction of the exudation fluid 
from a diseased lung into the healthy lungs of an animal. For 
the purpose of the experiment two sheep were selected, and 
into the lungs of each about two drachms of exudation fluid were 
injected by puncturing the organs with a finely-pointed tube
