A FEW OBSERVATIONS ON THE MORBID CHANGES 
THE LUNGS UNDERGO IN PNEUMONIA. 
By William Perciyall, M.R.C.S., and V.S. 
ADVERTING to the case of the trial—Bee v. Hayward—a 
full account of which was given in The Veterinarian for 
June, I would submit a few pathological observations, grounded 
on results of practice, with the view of coining to some con¬ 
clusions which might serve to reconcile, or rather, it would be 
hoped, to anticipate, and so prevent, variable and contradictory 
professional allegations apt to be made in evidence in courts of 
judicature, in no mean degree discreditable to us as a body of 
medical men practising under the title of veterinary surgeons. 
I need make no particular allusion to the case just mentioned, 
because trials of the sort are too numerous on record, and still 
are too frequently occurring, to render it necessary to make 
any special reference, save it be for the purpose of the elucida¬ 
tion or confirmation of any thing I may advance in opposition to 
opinions by too many, it is to be apprehended, at the present 
da} r entertained. 
Pleurisy and pneumonia must be regarded as inflammations 
correlative to that degree that independent existence, such as 
would warrant the application of the epithet pure to either, is 
hardly regarded as consistent with what is observed in human 
medicine; while in hippiatric medicine, it is notoriously still 
less so. Veterinary surgeons are warranted in giving almost to 
every case the name of pleuro-pneumonia , it being either a 
mixed pleurisy or a mixed pneumonia; notwithstanding, in 
every case one disease will be found to take the lead of the 
other ; or, in other words, bear the brunt of inflammatory action 
in preference to the other : so that in the one case we may fairly 
pronounce the horse to have died of pleurisy; while in the other 
we come as fairly to the conclusion that the cause of dissolution 
has been pneumonia. 
Nothing can be more vexatious for both parties concerned in 
a horse transaction, seller as well as buyer, than to experience
