sinks sometimes as early as the second day, and rarely lives 
beyond the fourth. 
The morbid lesions will be found centred in the mucous 
membranes, which are more or less affected throughout the 
entire body. Commencing at the mouth, it not unfrequently 
happens that some of the conical papillae, here and there, at 
their bases on the body of the tongue, will show that the 
epithelium is broken up by the ulcerative process. The root 
of the tongue, fauces, and velum palati are implicated to a 
greater or less extent ; their follicles are filled with effused 
tymph, giving to the parts an appearance as if dotted over 
with some yellow pigment. Some of the follicles are 
ulcerated, but the major portion are merely distended with 
lymph. 
The tonsils are in a similar condition ; and when a section 
is carried through their long diameter, large portions of 
lymph can be drawn from their ducts, the yellow colour of 
which, interspersed in lines, contrasts strongly with the red 
substance of these organs. Much turgescence of the vessels 
of the Schneiderian membrane, and points of ulceration and 
shreds of lymph, are met with about the posterior nasal 
opening, and base of the vomer. These lesions, however, 
rarely extend beyond the middle portion of the septum nasi. 
The pharynx presents the same appearances, but the oeso- 
phagus is healthy, as is the rumen and reticulum in most in- 
stances. In some few cases the epithelium readily peels from off 
the inner surface of these stomachs, when the vessels beneath 
will be found turgid with blood. The rumen is also found 
to contain a fair quantity of ingesta in the state usually met 
with in healthy animals. The omasum is without struc- 
tural change, or at most its mucous surface presents 
a like 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 d'urre has been given to the malady. In three con- 
secutive post-mortem examinations we found, however, that
