1889.] Schweine-Seuche and the "Swine Plague!' 889 
The most interesting and important point regarding these ob- 
servations is the relation of the lesions in the intestines to epi- 
zootic swine diseases in this country. In the fifty-two hogs ex- 
amined we do not find intestinal lesions mentioned once ; but do 
meet with such expressions, over and over again, as, " Nothing 
abnormal in the intestines." On the contrary, pulmonary changes 
var>'ing in degree were present in each case, and formed the 
essential lesion. 
Summing up the results of their microscopical observations, 
these investigators say that " the skin and sub-cutis showed no 
changes," which is somewhat contradicted by Schiitz and Loeff- 
ler's experience, both of whom frequently mention the presence 
of " enormous oedema." Going on they say, " In most cases the 
diseased changes were limited to grayish-red hepatization of the 
inferior portion of the anterior lobes of the lungs and medullary 
swelling of the lymph-glands. Further lesions were also present 
in the middle and inferior lobes ; the bronchial tubes always 
formed the central point of these consolidations. Where the dis- 
ease had become more progressed the hepatized tissues were 
more dry, and yellowish-red in color; coseation was present in 
still older centers. In the other organs, especially the cutis and 
sub-cutis, liver, kidneys, bladder and gastro-intestinal canal, no path- 
ological changes were to be seen. 
" Our investigations show that we have had to do with an ex- 
ceedingly infectious disease of the lungs having a chronic course, 
which can extend to healthy animals without any contact 7vith dis- 
eased ones (hence not contagious), and that the infecting element, 
in almost all cases, finds its way into the infested organism 
by means of the lungs. In all cases the pathological changes do 
not extend much beyond the point of invasion. The disease retains, 
almost invariably, a local character. Especially do we entirely miss 
any nientionable changes in the spleen and intestines:' 
The authors also quote Schiitz upon this point as follows : 
" Schweine-seuche (swine plague) is an inflammation of the 
lungs and pleurae which is found with necrosis of the diseased 
portions of the lungs and mild phenomena of infection, little or 
no swelling of the spleen, slight swelling of the parenchymatous
