converting the mucous surface into a yellowish irregular structure, 
like wash-leather, and in some instances extending through all the 
coats to the peritoneum, rendering the wall thick and inflexible. 
5th. In two cases most peculiar masses were met with in the 
colors, looking like warty excrescences, springing from the 
mucosa ; they are oval, and lie transversally to the axis of the 
gut, encircling about three-fourths of the tube and projecting 
from half an inch to one inch into the lumen. In the transverse 
directions they present a rounded concavity, while in the long 
axis of the bowel they are convex ; the surface is dark or yellow- 
brown, and sometimes shows concentric lines. On section a firm 
greyish-yellow structure is disclosed, very dense, and involving 
all the coats to the peritoneum, which is puckered and retracted 
over the site of the attachment.” 
After passing an examination of the histology of the lesions 
found, l > rof. W. Osier closes the paper by the following con¬ 
clusions : 
“ 1st. The so-called pig-typhoid is a disease sui generis, pre¬ 
senting anatomical and clinical features distinct from any other 
affections. 
“ 2d. It presents no analogies, either pathologically or clini¬ 
cally, with typhoid fever in man. , 
“ 3d. Neither has it any affinity with anthrax, as claimed by 
some continental writers. 
“ 4tli. If we take the intestinal lesions as characteristic, the 
disease must be regarded, with Dr. Murchison, as dysenteric in 
its nature, although the cutaneous and pulmonary affections, as 
well as certain of the clinical features, meet with no parallel in 
human dysentery.”— Yeterinary Journal.
