variably present, though, perhaps at times, difficult to dis¬ 
cover, to color, or to isolate ; and that, unless it is there , tuber¬ 
culosis DOES NOT exist —all this is proved beyond question 
or doubt in Koch’s “ JEtiology.” The modes of development, 
the processes of the biological studies which are required for 
the investigation ; everything discoverable, in fact, connected 
with this bacillus, are minutely, carefully, and thoroughly 
described and presented by the author to the inquiring student. 
With this work properly appreciated and well studied, there 
is no longer any reason for error of diagnosis in that fatal af¬ 
fection. The lesions are in many instances so characteristic 
that any error can scarcely be possible, and yet how frequently 
may it happen that lesions, of the lungs, for instance, often 
peculiar, may be of a tuberculous aspect and yet entirely 
different in their nature ! The pseudo-tubercles of the lungs, 
sometimes encountered, have no doubt in some instances led 
to a diagnosis of alleged phthisis, which would have been of 
an entirely different nature had the teachings of the author 
been followed, and the truth discerned, which the absence of 
the bacilli would have made certain, if it had but been rightly 
interpreted. 
“ Etiology of tuberculosis,” which has filled so impor¬ 
tant a place among German scientific authorities, may now 
perform the same good office for English-speaking veterinar¬ 
ians, and by such of us as may unfortunately have much to 
do with this disease in the United States, we hope it will be 
recognized as an instructor and assistant beyond any pos¬ 
sibility of rivalry or cavil, or chance of supercedure. 
Veterinary Appointment.— The progress accomplished 
by veterinary medicine in public estimation, and the impor¬ 
tance and value of the services which it is now conceded may 
be rendered by veterinarians in their legitimate sphere— 
looking over a retrospect of no more than five short years— 
may be justly viewed with surprise and satisfaction. Within 
a period a little longer than that no one would have imagined, 
outside of a dream, the important official positions which vet¬ 
erinarians are now called upon to fill. We well remember 
the ridicule and derision encountered by an amateur and
