340 REPORT OF THE COMMISSIONER OF AGRICULTURE. 
on the removal of the latter. The immediate surrounding of such a 
deep-seated degeneration presented some, but not very much, inflamma- 
tion. These morbid growths, usually, were found most developed near 
the ileo-cxcal valve in the cecum, but also in larger or smaller numbers, 
and of various sizes, large and small, in all parts of the cecum and 
colon. 
7. The same, or very similar morbid growths, occurred also, though 
not so often, in other intestines. In one case (experimental pig No. 
VII) a diffuse, decaying morbid growth coated the whole interior sur- 
face of the jejunum for a length of several feet. Examined under the 
microscope it was found to consist of broken-down epithelium cells and 
a granular detritus, and contained numerous bacilli and bacillus-germs, 
(See drawing VI, fig. 1.) 
In another case one ulcerous tumor was found on the mucous mem- 
brane of the gall-bladder. In three cases the same, or at least very 
similar morbid changes, presented themselves on the mucous membrane 
of the stomach. (See photograph, Plate VIII.) In a few cases some 
ulcerous tumors were found in the duodenum, and in one case even in 
the right horn of the uterus. In a few cases similar morbid changes— 
small, knotty, tubercle-like, yellowish, or ocher-colored excrescences of 
the size of a small pea—were found on the surface of the spleen. In 
one case similar small excrescences were also found on the external sur- 
face of the vena cava posterior. In two cases the liver was found to be 
degenerated by an hypertrophic condition of the connective tissue, a 
morbid change which may or may not constitute a product of the mor- 
bid process of swine-plague. 
8. Morbid changes in the serous membranes of the abdominal cavity. 
In some cases the peritoneum and the serous membranes of the intes- 
tines appeared to be perfectly smooth, but a larger or smaller quantity 
of straw-colored serum, from two ounces to one quart or more, was found 
in the abdominal cavity. In others, adhesions between the intestines 
and the peritoneum, between the intestines themselves, or with other 
organs, had been effected. More or less coalescence between cecum 
and colon, between cecum and ilium, or between the convolutes of the 
colon, sometimes not separable except by means of the knife, presented 
itself in almost every case, in which the ulcerous tumors or morbid 
growths in the cecum and colon were extensive, large, and sufficiently 
deep-seated to afiect the serous membrane. 
9, The contents of the gail-bladder in a large number of cases were 
found to consist of a semi-solid, granular, and dirty brownish-colored 
substance. In most of those cases, however, the ductus choledochus 
appeared to be thickened, and its membranes swelled; and so it may 
be that the semi-solid condition of the bile was due, to some extent, to 
the partially or totally obstructed passage. 
10. In one ease a morbid enlargement or hypertrophy of the pancreas 
presented itself, and slight changes (congestion) were found in a few 
cases in the kidneys. 
11. Morbid changes, similar in every respect to those occurring on the 
mucous membrane of the ewcum and colon, presented themselves in 
two cases on the conjunctiva, or mucous membrane of the eye. But as 
the conjunctiva is exposed more or less to the influence of the atmosphere, 
the morbid growth was not projecting in the same way as in the cecum 
and colon above the surface of the membrane; the decay was more com- 
plete, and, perhaps, more rapid, so that instead of an excessive growth 
loss of tissue could be noticed. In both cases the eyes themselves 
appeared congested, and the animals seemed to be perfectly blind.
