Professor Yen's opinion is strongly supported by the generally 
admitted fact that the bronchial and peri-bronchial lesions are of 
older standing than those of the parenchyma, while the pleuritic 
are the most recent of all. He says: 
“ I can well understand how a beast, by sniffing the fodder of 
a diseased neighbor, may draw into its air passages some of the 
dried discharge, and thus infect the bronchial mucus membrane 
and get pleuro-pneumonia, while all the skill of science will not 
induce the disease of the lung” by inoculation with the same ma 
terial. 
Of more importance is the question whether pleuro-pneumonic 
meat is fit for human food or not. The Dublin Sanitary Associa¬ 
tion appointed a committee to examine the question, and after a 
full enquiry they reported decidedly against its use. On the other 
hand, another committee, appointed by a different society, but com¬ 
posed of equally distinguished medical men, and after as careful 
an examination, say: “ It follows * * that the jresh 
and unchanged meat of animals slaughtered during an attack of 
pleuro-pneumonia may be safely consumed, and that such meat is 
not sensibly less in nutritive value than that of other animals un¬ 
affected by any disease, but that it is of inferior quality.” 
There can be little doubt that this is the case; in the early 
stages it is perfectly fit for human food. 
Dr. Blake White has carefully examined the milk of cows suf¬ 
fering from pleuro-pneumonia, and he reports it as decidedly unfit 
for human food. He says : “ I have no hesitancy in pronouncing 
these samples of milk not only unwholesome, but in consequence 
of the very low percentage of fat, innutritions, and showing in 
every way what a depreciating effect unwholesome and insufficient 
food lias upon tin's important secretion.”*
