Hemorrhagic Meningitis in a Cow.-^ —A twelve-year-old 
cow, well nourished, lost appetite one day, fell down next day 
and showed upon examination by the author the following clin¬ 
ical picture : The eyes were half closed and had a dull look ; one 
pupil was contracted, the corneal sensibility was diminished, 
cutaneous sensibility likewise, although there was no decided 
anaesthesia ; the induction current caused a very strong reaction 
the forcibly drawn out tongue was immediately drawn in again. 
Muscular activity, especially in the rear half of the body, was 
disturbed. The temperature was 40° C., respiration deep but 
unlabored. Milk secretion was diminished. Next day the pulse 
was feebler, respiration stertorous, and peristalsis audible ; the 
paralysis, diminished sensibility, etc., were the same as upon the 
day previous. On the third day the pulse was very feeble and 
thready, the heart impulse fluttering, respiration very deep and 
labored ; the lower halves of both lungs were unaereated, there 
were friction sounds heard upon expiration. The animal was 
thereupon slaughtered. Autopsy showed : Liver, spleen, kid¬ 
neys, gastro-intestinal tract normal. The lungs were attached 
to the chest wall at their lower borders by fibrinous adhesions ; 
the pleurae were thickened, congested, dull, with fibrinous de¬ 
posits upon their surfaces. The affected portions of both lungs, 
i. e., the lower half of the right lung and the lower two-thirds of 
the left lung were wholly airless, solid and juicy, but relatively 
anaemic. The bronchi and bronchioles were partly filled with 
bloody serum, partly with reddish foam. The heart and blood 
were normal. Upon opening the cranium a considerable quan¬ 
tity of yellowish serous fluid exuded, chiefly located in the space 
between the dura and pia mater. The pia mater was thickened 
and velvety to the touch. In the left hemisphere in front a 
broad extravasation, covering nearly the whole surface of the 
pia mater and extending backward to the olfactory lobes, showed 
itself. The pia mater, even as far backward as both olfactory lobes, 
was thickened and hemorrhagic. The ventricles and blood ves¬ 
sels were distended. The parenchyma of the brain was little 
altered. This condition of affairs in the brain undoubtedly ex¬ 
plained the physical symptoms. The cause of the meningitis, 
traumatism being excluded, was hard to determine. The sudden 
and marked onset of the symptoms of depression were probably 
due to the sudden rupture of the ventricles, whose elasticity was, 
considering the age of the cow, probably markedly impaired.—
