Two Cases of Generalized Tuberculosis in Horses 
[By Knipsher\ .—As it is important to publish all the cases of 
tuberculosis in horses, the author publishes the following made 
in his artillery regiment observations : Both cases showed al¬ 
most the same symptoms ; but a diagnosis was only made on 
the second horse on the grounds of the autopsy of the first case. 
Both horses had good appetites, almost until death, at the same 
time becoming more and more emaciated and losing strength. 
There was hardly a change in the pulse, respiration and tem¬ 
perature ; discharge from the nose and cough were absent, also 
all the changes on percussion and auscultation. All that was 
striking was the continual loss of flesh, without any explain¬ 
able reason ; the very pale conjunctiva, and at the end the 
swelling of the hind extremities, and the beginning of poly¬ 
dipsia and polyuria. Examination of the urine showed only a 
slight quantity of albumen ; sugar ; kidney epithelia, etc., were 
not present. On post-mortem of the first horse, it was found 
that almost all of the organs contained different sized tubercu¬ 
lar nodules, the most affected proved to be the greatly hyper¬ 
trophied lung and bronchial lymphatic glands. The second 
horse was affected in a milder way, as the intestines, liver and 
kidneys were normal ; on the lungs and mesentery could only 
be noticed small herds of tubercular nodules. On the spleen 
there was found a tubercular new formation of the size of a 
hazel nut, and on the diaphragm, one of the size of a pigeon’s 
egg. All over, however, especially in the bronchial secretions, 
were found numerous bacilli of Koeh. From these conditions 
it can be easily noticed. As to the few symptoms we can ob¬ 
serve in a case of generalized tuberculosis in a horse, intra 
vitam , as even the strongly affected lung will not give any dis¬ 
closure, so as in the absence of a nasal discharge the diagnosis 
is very difficult or impossible. A rather more supporting 
point is the increased thirst and polyuria near the termination 
of the disease, and both these symptoms, as has been observed, 
seem to occur in almost every case of which the motive is not 
explained yet. Nocard observed polyuria lately in eleven cases 
of abdominal tuberculosis in horses.—( Deutche Thierart.

Contribution to the Study and Pathology of Par¬ 
turient Apoplexy [By Dr. H. Van de Velde\ .—The study 
of parturient apoplexy by the author, brought out a new theory 
with the conclusions that the disease is caused by different 
micro-organisms, either single or mixed (streptococci, staphy-
