costivcncss, or any of the symptoms before alluded to under llie 
head of premonitory, which would lead us to suspect the approach 
of inflammation of the pleura, or of the lunjr itself, the animal 
should at once be removed into a comfortable and airy hovel 
taking care at the same time to place it in such a way as not to 
expose it to any direct currents of air. It should then be bled, and 
repeated, if necessary, within a few hours ; but we have generally 
found one bleeding suffice, except occasionally in stall-fed beasts 
or cattle in high condition. 
Bleeding is the most valuable means we can emj)loy in order to 
restrain or extinguish the incipient inflammatory action of the 
lungs or pleura at this period. 
Some general rules may be laid down with respect to the man- 
ner and quantitv in which blood should be extracted. The earlier 
it is peribrmed after the above symptoms have appeared the better 
will be the chance of recovery. The patient should be bled from 
a large orifice and in a full stream, and continued until some de- 
cided effect is produced upon the system, which may be known 
by the pulse becoming stronger if it were oppressed, or lowered 
if previously strong and full ; the quantity drawn will also depend 
upon these circumstances. After bleeding, it will be advisable 
to have recourse to medicines calculated to promote the discharge 
of the secretions, and at the same time diminish febrile excite- 
ment. This object will be best gained by the administration of 
a saline purgative combined with Potass. Nitrat. and Ant. Tart 
in something like the following form :

This may be given once a day (till the bowels are freely opened) 
in two quarts of warm gruel, made either of flour or oatmeal, or 
in the same quantity of linseed tea. 
Should the before-mentioned sjmptoms increase in severity, 
the beast become more spiritless, cough and heaving at the flank 
more frequent, grunting louder, appetite nearly or quite gone, 
with other symptoms indicating that the second stage of the 
disorder has set in. The antiphlogistic treatment should be at 
once discontinued, and extensive counter-irritation had recourse 
to, and also the exhibition of remedies that will l)est tend to arrest 
the effusion and promote its absorption. Mercury possesses this 
peculiar power in a certain degree, but it is a medicine that re- 
quires to be closely watched, as it is liable to produce super- 
purgation, but not of such an uncontrollable nature as we have 
sometimes observed in the horse, when the smallest dose would 
produce this effect; it should be combined with opium to guard 
its action upon the bowels, and given in thick gruel, as in the 
following form :
