EDITORIAL OBSERVATIONS. 
this stomach and its contents were normal. The mucous 
membrane of the abomasum is highly congested, more par- 
ticularly towards the pylorus ; and its follicles are in an 
analogous state to those of the velum. The duodenum, 
jejunum, and ileum are similarly affected, but to a greater 
extent. These intestines also often present a bluish aspect 
on their serous surface, but which is entirely due to the 
turgescence of the vessels of the mucous membrane giving a 
depth of colour to it which is seen through the other coats. 
Peyer’s glands are not invariably diseased, but, like other 
follicular openings, they are often found covered with layers of 
lymph, beneath which ulceration is occasionally seen, but 
more often the surface is healthy, although turgid with blood. 
The chief ravages of the disease have been by us met with 
in the large intestines. The blind end of the colon — the 
caecum — was, in one case in particular, ulcerated over 
several inches of surface ; that is, numerous small and dis- 
tinct ulcers existed, which had evidently had their origin in 
the follicles of the intestine. Deposits of lymph, varying in 
size from that of a pea to the end of the finger — scabs, as 
they have been designated — studded the large intestines almost 
throughout their whole extent. They were of a dirty-yellow 
colour, and adhered with tolerable firmness to the mucous 
membrane. In some places ulceration was found to be going 
on beneath them ; in others this destructive process had 
ceased and the healing one has commenced; and in most no 
change in structure could be observed. 
The substance of the liver is healthy ; in all cases the gall- 
ducts, however, contain layers of effused lymph, and sometimes 
to an amount sufficient to block up their passages. The gall- 
bladder is filled with bile possessing its ordinary characters, but 
the inner surface of the bladder is precisely in the same state 
as the mucous membrane of the large intestines. The kidneys 
are healthy, and the urinary and generative systems unaffected. 
The larynx is occasionally slightly ulcerated, particularly 
on the edge of the arytaenoid cartilages ; no ulceration, 
however, has been seen by us throughout the whole extent of 
the windpipe and bronchial tubes; but thin layers of effused
