DISEASES OF THE SUBMAXTLLARY LYMPH GLANDS.

in actinomycosis of the jaw. Frick confirms this. The piognosis 
depends on the extent to which mastication is interfered with, and on 
whether the animal can still be used for any purpose. It is better to 
slaughter, immediately the general condition begins to suffer. 1 ost- 
mortem shows the bones to be perforated with granulation masses and 
pus cavities. The existing osteoporosis is most cleaily seen aftei 
macerating the bone (fig. 62). 
Treatment, even when early adopted, offers little hope. Loose teeth 
must be removed under any circumstances, the alveoli afterwards 
washed out with a disinfectant fluid, and plugged with tow saturated 
with tincture of iodine. Where abscesses have already perforated, anti¬ 
septic injections may be tried. Tincture of iodine seems to deserve 
preference. The internal administration of iodide of potassium has 
been extensively tried in this disease, but with very varied and often 
negative results. Moussu’s experience leads him to prefer energetic 
curettage of the parts and subsequent internal use of potassium iodide. 
But more important than these therapeutic measures is the adminis¬ 
tration of such food as makes little call on mastication, as brewers’ or 
distillers’ grains. 
Pilz gave an eighteen months old foal 4 to 5 drams of iodide of potassium, and 
injected the swelling with tincture of iodine daily. In five weeks symptoms 
of poisoning occurred, appetite and condition were lost, the coat was dry and 
staring, the limbs swollen, and pulse accelerated, but these symptoms disap¬ 
peared after the material had been discontinued for a fortnight. Iodide ot 
potassium was afterwards given for periods of fourteen days at a time, unti 
two pounds of iodide of potassium and one pound of tincture of iodine had 
been used. At the same time the parts were regularly washed out with 
different materials. Great improvement was noted ; but as the foal was soon 
afterwards sold, the final result of the treatment could not be determined. 
(9.) INFLAMMATION AND NEW GROWTHS IN THE 
SUBMAXTLLARY LYMPH GLANDS. 
Infectious processes in the lips, nose, cheeks, or nostrils usually cause 
swelling of the submaxillary lymph glands. This is especially noted in 
glanders, strangles, certain forms of cellulitis, and also in some malig¬ 
nant new growths, such as carcinoma, mycofibroma, and actinomycosis. 
In the last-named disease chronic lymphadenitis, accompanied by 
marked swelling, pus formation, and ulceration, may also occur. 
Horses, oxen, and dogs all suffer from primary tumours of the 
submaxillary lymphatic glands, in which lymphomata, atheiomata, 
and carcinomata are occasionally found. 
Symptoms. The acute inflammatory diseases of the submaxillary glands 
are described in works on pathology. The chronic are characterised
