REPORT ON THE CATTLE PLAGUE.

which, interspersed in lines along the course of these pas- 
sages, contrasts strongly with the red substance of the organs. 
Much turgescence of the vessels of the Schneiderian mem- 
brane, with points of ulceration and shreds of lymph, are 
met with, more particularly about the posterior nasal open- 
ing, and base of the vomer. These lesions, however, rarely 
extend beyond the middle portion of the septum nasi . 
The pharynx presents the same appearance, but the oeso- 
phagus is healthy, as is both the rumen and reticulum in 
most cases. In some few instances the epithelium readily 
peels from off the inner surface of these stomachs, when the 
vessels beneath are found to be turgid with blood. The 
rumen invariably contains a fair quantity of ingesta in the 
state usually met with in healthy animals. The omasum is 
without structural change, or at most its mucous surface 
presents an analogous condition to that of the rumen and 
reticulum. The contents of the omasum are frequently so 
dry and hard that they can be rubbed to powder between the 
fingers. This has been considered by many Continental 
pathologists as a peculiarity attaching to this disease, and 
hence the term Loser dilrre has been given to the malady. 
In three consecutive post-mortem examinations, as well as in 
many others, we found that no alteration, either of the 
omasum or of its contents, existed which was incompatible 
with perfect health. 
The mucous membrane of the abomasum is always highly 
congested, more especially towards the pylorus ; and its 
follicles are in an analogous state to those of the fauces, 
velum , &c. The duodenum, jejunum, and ileum are similarly 
affected, but to a greater extent. These intestines often 
present a bluish aspect on their serous surface, but which is 
entirely due to the turgescence of the vessels of the mucous 
membrane beneath, which being seen through the other coats, 
gives a greater depth of colour to it than natural. Peyer’s 
glands are not invariably diseased, but, like other follicular 
openings of the digestive canal, they are often covered with 
layers of lymph, beneath which ulceration is occasionally ob- 
served ; but more frequently the surface is healthy, although 
turgid with blood.
