ON SOME OF THE DISEASES OF THE RESPI¬ 
RATORY ORGANS OF THE HORSE AND 
OTHER ANIMALS. 
By Professor Brown, M.R.C.Y.S., London. 
{Contmued fromp. 45G.) 
Humoural pathology, as expounded by the old school, is 
of necessity revived^ in our day under a variety of new titles. 
It no longer being permitted to the scientific man to talk of 
the ‘^Giumoursin the system, he takes refuge in the terms 
morbid matters,“blood poisons,^^ or something whicli 
may express his idea that there is in the animal a material 
W’hich is essentially injurious, and whose presence is produc¬ 
tive of a certain condition, which is denominated unhealthy. 
There may be no positive disease of any organ, but any little 
derangement is likely to be more than ordinarily troublesome. 
A slight wound discharges constantly, or ulcerates, and refuses 
to heal; the legs swell, one of them particularly; the heels 
are chapped, thrushes appear; and the groom sums up the 
whole matter by stating , bis conviction that the horse is 
“ humoury while the veterinary surgeon has the satisfaction 
of reflecting that he cannot much improve upon the explana¬ 
tion. Whatever name be given to the state described, one 
thing is evident enough, the animal so circumstanced is a 
very unsatisfactory subject to treat if attacked by influenza 
or common catarrh. All sorts of evils may be apprehended— 
nasal gleet, abscesses in the fauces and other parts, extensive 
oedematous swellings, painful tumefaction of some of the ex¬ 
tremities, congestion of lungs, and throughout fever of a 
low character associated with great prostration. AVhether 
glanders and farcy may arise spontaneously out of this con¬ 
dition of system, when aggravated by a febrile attack, we do 
not pretend to decide, but there is no doubt that these 
diseases occasionally present themselves as sequelae; their 
prevalence, however, and the numerous sources of contami¬ 
nation, argue strongly against their spontaneous origin. 
The complication of a catarrhal affection with abscesses 
is the most common, and one of the most annoying, on
