excessive irritation that their lumena are completely filled with a 
muco-purulent mass. The catarrhal products often extend from 
the nasal cavities to the frontal and lateral sinuses of the head, 
filling: them with a more or less dense secretion of a similar char- 
acter. The catarrhal products can also extend through the Eus¬ 
tachian tubes to the guttural pouches. When the irritation is very 
violent, the secretions acquire a haemorrhagic character. These 
secondary inflammations often complicate the deeper-seated tis¬ 
sues. The mucosa, and also the submucosa of the nasal cavities, 
become intensely swollen and oedematous. In the larynx such 
processes often cause “ oedema glottidis.” 
When the infiltrative processes have reached a certain depth 
in the tissues, a purulent perichondritis is often found in the 
septum nasi and larynx, frequently leading to necrosis and per¬ 
foration, or to serious cicatricial retractions. 
The ulcerations in the glands, either primary or secondary, 
often heal by cicatrization. These cicatrices have a more or less 
stellate form. When the ulcerative processes extend equally in 
all directions from a primary nodulus, the healing commences in 
the center, while the neoplastic and ulcerative processes extend at 
the peripheries. These large ulcerations also heal by the granu¬ 
lations, and are frequently the seat of more or less extensive 
haemorrhages. This cicatrization does not always occur in a harm¬ 
less manner; all sorts of malformations in the complicated parts 
may occur—even the utter destruction of diseased tubes or 
cavities. Definite healing seldom results, for new noduli and 
ulcers frequently develop under the cicatricial tissue or in. its cir¬ 
cumference ; similar processes also develop within the cicatrices, 
giving the impression that the latter were also the object of den- 
teropatliic invasion—hence cicatrization is not always the termina¬ 
tion in glanders, but simply a part of the same. 
The processes in the skin, as well as the mucosa, are generally 
accompanied by complications of the lymphatic system, which are 
of a secondary nature aud bear direct connection with those parts 
from which the glands receive their lymph. The contagious prin¬ 
ciple is taken up by the lymphatics in and around the primary 
diseased localities and conveyed to the first lymph-glands in their
