230 SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 
We may observe how letters have been written step by step 
with the impressions of the observer, who, struck at first with 
the many marked differences which occur between two con¬ 
ditions reputed to be of the same nature, finds himself 
compelled nevertheless to identify them according to the 
classification of Chabert, which had been long accepted as 
the expression of a truth demonstrated by rigorous observa¬ 
tion. Later, in the presence of the so different modes of 
manifestation of the disease which he observed, and especially 
from the results, always negative, of the inoculations of one 
of them, M. Yernat feels his faith wavering; he expresses 
his doubts; he appeals to experimentation to give a solution 
of a matter of which clinical study can only supply the data; 
he is anxious that experiments be made in the same places 
where the disease occurs, in order that trial may be made to 
discover the Bacteridia; and then, at last, casting off the 
doctrinal ideas which have for some time restrained his 
clinical acumen, he declares definitely in his third letter 
“ external charbon is of a different nature from splenic 
fever/’ And he goes on to point out the clinical characters 
by which the two diseases may be distinguished and the 
results of inoculation, which show that while splenic fever is 
constantly contagious, external charbon has never been 
transmitted. The experiments made at the Lyons School 
are in every respect confirmatory of the views of the practi¬ 
tioner of Clamency, whose clinical observations and experi¬ 
ments constitute a valuable contingent to the proofs now 
collected, tending to disprove the anthrax nature of the 
symptomatic charbon of Chabert. If the disease is not 
anthrax, what is it? The experiments at Lyons will doubt¬ 
less tell us !” 
In our last synopsis we alluded to the fact that the question 
whether simple sporadic and non-contagious pneumonia 
of the bovine species exists distinct from pleuro-pneumonia 
zymotica, but producing apparently lesions of a like cha¬ 
racter is subjudice . The Journal de Medecine VeUrinaire for 
February, 1880, contains an original article by M. Violet 
“ On the Question of the Independent Existence of Ordinary 
Pneumonia of the Ox. The title placed at the head of this 
article will raise a smile on the countenance of more than 
one practitioner long accustomed to combat diseases of the 
animal which it concerns. Nevertheless, the examination 
of the question is not so puerile as it may seem to some, 
for recently the solution of the question raised has occupied 
the attention of the Societe Centrale de Medecine Veterinaire, 
to which an author, as yet unknown, has sent in competi-
