VETERINARY JURISPRUDENCE. 
disease. Here again I think we have evidence of an irresistible 
kind, showing that the cause, whatever that may have been, was at 
once entirely removed. 
I have two other examples that I could relate ; they are parallel 
cases, and equally successful. I am fully convinced that in every 
large concern, whether it be of ’bus, cab, or other horses, the persons 
concerned may by an intelligent adoption of the above method rid the 
stables at once and permanently of any and every contagious or 
infectious disease, and I verily believe if in the days of the cattle 
plague and pleuro-pneumonia, every shippen was ventilated as 
above recommended, and had had. a good open stove fire in it, 
and a few tablespoonfuls of petroleum or paraffin oil spilt upon the 
floor and burnt in each boose once or twice every day, the disease 
would in all probability have been greatly modified, if not entirely 
arrested. We are as yet but in the infancy of an understanding of 
the subject of aerial poisons. Only a little knowledge on this head 
might at times ward off momentous consequences. I look upon 
this as the highest truths of science that our profession can teach. 
I believe there are those who would contend that these examples 
that I have narrated are great achievements, a triumph of science 
and experience. They are now laid before your notice, possessing 
as they do ample matter for reflection, great and most important 
facts for you to ponder over, especially as to the soundness of the 
doctrine of incubation. They are not— 
“Baseless as the fabric of a vision,” 
but are useful convincing truths, calculated to lead our minds to 
take broader views of our noble profession, making it more exten¬ 
sively useful. Thus it will be seen that as science removes the mists 
which obscure our mental vision, and circumscribe our knowledge, 
disclosing to us at the same time the awful grandeur of the truth 
as it exists around us in nature, will our senses become expanded 
and capable of contemplating and realising the wisdom, power, and 
goodness of our great Creator.

THE PROPAGATION OF CATTLE DISEASE BY RAILWAYS. 
At the Birkenhead police court, December 4th, an information 
was laid against the London and North-Western Railway Company 
for using trucks for cattle without being properly disinfected. It 
was proved that on the 2nd of November two cows suffering from 
pleuro-pneumonia were found in one of the defendant’s trucks, 
which was in a very filthy condition. 
The defendants were fined £10,
