INFLAMMATION OF THE UDDER IN A COW. 667 
which surrounds the glandular mass, or in that which penetrates 
into and envelopes the lobules and granulations of this organ, or the 
surface of the mucous membrane which lines the lactiferous canals. 
In certain cases it appears in these three varieties at the same 
time. 
We may form the prognosis that mammitis will terminate in 
suppuration if it is accompanied by the following symptoms; viz. 
considerable engorgement, partial or general, of the teat, accom¬ 
panied by hardness, heat, and evident pain in this organ—the skin 
dry, red, and glossy—the teats enlarged, lengthened, and painful on 
the slightest touch—the milk of a bad character, little in quantity, 
serous, of a dirty white colour, and generally mingled with a great 
quantity of clots of a milky or bloody character, or, sometimes, 
consisting of pure blood. When the inflammation is very intense, 
nothing can be obtained from the teats but a serous liquid of a red 
colour. The sound side of the udder, if one does remain sound, 
yields only a small quantity of milk, and that often very much de¬ 
teriorated in quality. 
When the disease is arrived at this point, a general reaction of 
the system is almost always manifest. The pulse has a febrile 
character—the mouth is clammy and hot—the muzzle dry-—the 
mucous membrane injected—the coat roughened—the alvine dejec¬ 
tions hard and glossy, or, perhaps, a frequent foetid diarrhoea—the 
urine small in quantity and high-coloured—the appetite, rumina¬ 
tion, and secretion of milk very much diminished—a sadness of 
the countenance—the flanks tucked up—the animal rarely lying 
down, except compelled to do so by absolute fatigue, and, even then, 
rising again almost immediately. 
When the inflammation is terminating by a mucous discharge 
from the lactiferous canals, it will be advisable carefully to examine 
the udder, particularly towards its base. There will be almost in¬ 
variably found, more or less deep in it, a cord or nodes, the result 
of the engorgement of the excretory canals. 
Other phenomena are not slow in succeeding to these. The 
matter furnished by the lactiferous canals becomes purulent, thick, 
and curdled—the surface of the teat is hardened in one or more 
points—the redness becomes more intense, or often assumes a livid 
colour. Tlie careful observer will then not be long in recognizing 
a spot, more or less extended, in which the udder is beginning to 
soften, and fluctuation may be detected beneath it. This, being left 
alone, opens of its own accord, if the medical attendant should have 
foolishly neglected to puncture it with a lancet. There ordinarily 
issues from this opening a great quantity of pus of a strong and 
disagreeable odour, that was contained in reservoirs more or less 
deep. Sometimes the mammillary gland is almost denuded of its
