severe. Quality of milk not much changed; quantity 
diminishes. Slight fever at commencement ; swelling 
of the lymphatics of udder, which spreads. Condition 
may disappear in four to eight days. In other cases 
abscesses form in or just beneath the skin; less fre- 
quently, in the superficial portions of the gland, these 
break and discharge pus. 
Treatment.—Cold applications contra-indicated. 
Best results from infrictions with mild fats, like oil, or 
with carbolized oil, blue ointment, etc. The parts 
washed with lukewarm disinfectant solutions, especially 
if the teats are injured. Udder kept warm, and may 
be suspended to assist resolution. Local injuries 
cleansed and disinfected. 
Parenchymatous Inflammation, of which there are 
three forms, distinguished, viz.: mastztes catarrhalis, 
mastitrs apostematosa, and mastitis gangrenosa. 
MASTITIS CATARRHALIS, 
This condition consists of inflammation of the lining 
membrane of the milk ducts. 
Symptoms.—Surface of udder little changed; swell- 
ing often wanting, while redness may be slight, but 
deep-seated pain can be detected on pressure, and by 
sensitiveness during milking. General condition little 
altered. The principal changes are found in the milk, 
which contains clots of varying sizes, and often drops 
of fat; sometimes it is slightly tinged with blood. 
The disease sets in suddenly, and may attack only 
one, or several sections of the gland.
