yellow color, which occur in nests or are disseminated over the 
gland, and occur either in the medullary or cortical portion of the 
gland. The other parts of the gland are in a condition of cellular 
hyperplasia of a simple irritative character. The yellow spots 
become larger, and undergo purulent degeneration or desiccation 
(necrobiosis), forming caseous conglomerates or noduli. These 
abscesses or conglomerates frequently occur in the midst of a hy¬ 
pertrophied gland. The specific irritant having gained access to 
the gland, causes the development of chronic, indurative condi¬ 
tions. 
Glanders being a specific disease, the pathological disturbances 
must be divided into (1) primary or specific, and (2) secondary or 
simple inflammatory processes. The one class may be compared 
to those which follow any form of irritation; the other, on the 
contrary, possess peculiarities which are specific to glanders. 
In glanders the entire gland is seldom found complicated; as 
a rule, single parts or lobuli of the glands are more affected than 
others. 
Suppurative processes in or around lymph-glands, which 
finally escape outwards, are very rare in glanders. Simple sup¬ 
purative inflammatory processes can, on healing, leave the glands 
in a condition resembling that of glanders. The contents of such 
abscesses can desiccate and become cheesy, or peri-oednoid indura¬ 
tions may occur by which the glands become hard and more or 
less attached to surrounding structures. 
When in specific disease of lymph-glands in glanders, other cen¬ 
ters of disease occur, and a viscid, purulent mass forms the con¬ 
tents of the gland, and the cells undergo disintegration, leaving a 
fatty detritus; the cavities being filled with a soft mass of fat 
granules, and the noduli do not become completely caseated, but 
acquire a soft, yellowish center—these are valuable points for 
differential diagnosis. If doubts still remain, they can be re¬ 
moved by giving special attention to the condition at the primary 
seats of disease, or by microscopic examination of the contents of 
the noduli. 
Lympli-glands in a condition of simple hypertrophy frequently 
undergo a mild form of fatty metamorphosis. A cross-section of
