cellular texture in different parts. In this case a long suppurative 
process will be established, and fistulae will be formed, resulting from 
the ramollissement of some of the inflamed points. These will pro¬ 
duce new reservoirs of purulent matter, the healing of which it will 
be difficult to effect. 
At this period of the affection the general and constitutional phe¬ 
nomena will usually disappear. The appetite and rumination will 
return—the tension and pain of the udder will diminish—the sup¬ 
puration from the teats will become less abundant, and the secre¬ 
tion of milk will by degrees reappear. 
I Avould here repeat—what I have already stated—that phlegmon¬ 
ous inflammation of the udder may exist in conjunction with ca¬ 
tarrhal inflammation. 
The lesions which may follow this mode of termination of the 
disease, when the inflammation has been very acute, are callosities 
or nodes in the substance of the gland or on its surface, or engorge¬ 
ment of the lactiferous canals. 
When these lesions exist, the secretion of milk is considerably 
diminished in the diseased gland, and sometimes it is entirely sup¬ 
pressed, or does not reappear until the next calving : but, oftener, 
if a complete resolution has not been effected during the course of 
the suckling or milking, it is much to be feared that the new preg¬ 
nancy will only lead to complete loss of the udder. 
Induration .—This mode of termination is, unhappily, that which 
most commonly follows suppuration. It pursues nearly the same 
course as the preceding one, except that there is less intensity at 
its commencement. 
The symptoms which lead us to fear the termination by indura¬ 
tion of the gland, partial or general, or by obstruction of the excre¬ 
tory canals, are the exhalation of serosity of a red colour, and of a 
small quantity, by means of these canals; or oftener, the total sup¬ 
pression of all exhalation, accompanied by intense inflammation of 
the body of the teat. 
Gangrene .—This is a termination the most of all to be feared ; 
for not only it involves inevitably the destruction of a portion of 
the organs which it attacks, but it sometimes occasions the death of 
the animal. 
The symptoms which announce gangrene differ from the pre¬ 
ceding ones only by their greater intensity. The general pheno¬ 
mena are more decidedly marked—there is extreme depression 
of strength and spirits, and great heaving at the flanks. Soon we 
perceive on the body of the udder a surface of greater or less 
extent, and of an obscure red or livid colour. If this surface is 
examined, a fluctuation is distinctly perceived beneath. The fluid 
which runs from it, when it is suffered to break spontaneously or
