896 The Americmi Naturalist. [October. 
ticipation of the future I will draw attention to a disease of swine 
described by Roloff, under the name of caseous enteritis, which 
most probably should be recognized among the pathological 
processes caused by the the ovoid bacteria " of Schweine-seuche. 
Peters seems to be well aware of the fact that Schutz did not 
meet with these lesions in any of the hogs he examined, for he 
says : " We distinguish two etiologically different diseases, the 
Rothlauf of swine, and the Schweine-seuche : the first is pure 
septicaemia, caused by a bacillus, the last a general disease caused 
by an ovoid bacterium, in the course of which, so far as known, 
a multiple mortifying pneumonia is developed. The anatomical 
picture of such a pneumonia was at least presented by all the 
swine examined by Prof Schutz." 
The work of Bleisch and Fiedeler seems to have been un- 
known to Peters. Aside, then, from the before-mentioned refer- 
ence to Roloff 's observations in 1875, it is evident that the 
German investigators acknowledge but two specific swine diseases 
in that country, and while I do not desire to be a special pleader 
for my own hypothesis as to the conditions there, still it is only 
fair to call attention to a peculiar result of the appearance of the 
Loeffler-Schutz Schweine-seuche in the pathological arena, and 
that is, we hear no more of the " Wild-seuche." As previously 
noted, Peters follows Schutz implicitly, and assumes the latter's 
hypothesis as to the Roloff lesions in the intestines to be unquali- 
fiedly correct, and says, " for the correctness of the assumption 
that the caseous enteritis should be classed with the Schweine- 
sueche, I am in a position to furnish the necessary material. 
" The necroscopies which I have made upon such swine did 
not all give a corresponding result, on the contrary, the bacterial 
results were the same in every case, namely, the presence of ovoid 
bacteria. In four of the cadavers the pathological changes were 
exclusively in the large intestine, in one other alone, besides these, 
there was a multiple necrotic pneumonia." 
It is not necessary to quote the details of the microscopical ex- 
amination of these five hogs, of the results of which Peters says : 
" Through the previous examinations it can well be considered as 
proven that all the swine examined had suffered from one and
