thirty-one cases was 105. 4, and the average number of hours 
after injection before the maximum temperature was reached was 
fifteen hours. 
In the Wisconsin Experiment Station herd from .4CC to .icc 
of tuberculin to an animal was used. 
The average highest temperature of the twenty-one that re¬ 
acted under the first test was 105. 5, and the average time to the 
highest temperature was fifteen and a half hours. 
The New Jersey State College herd was tested with an 
average dose for mature animals of .31CC. 
The average highest temperature of twenty-five animals that 
reacted was 104.9 i n an average time of sixteen hours. One 
cow in an advanced stage of tuberculosis was given -5 CC > but 
failed to react. 
In December, 1893, the Vermont Experiment Station herd 
was tested with from .2cc to .30c to each mature animal. 
Twenty-three animals reacted with an average highest tem¬ 
perature of 105.8 in sixteen hours. 
I might go on adding to these figures the record of other 
herds, but perhaps this is sufficient to show that the reaction is 
as decisive and as quickly obtained with a small as with a laige 
dose of tuberculin. 
ACUTE CEREBRAL INFLAMMATION EMBRACING CEREBRITIS AND 
MENINGITIS. 
By C. F. Dwinal, D.V.S., Bangor, Me. 
A paper read before the Maine Veterinary Medical Association. 
Mr. President and Gentlemen: —To comply with a re¬ 
quest from the president, Dr. Bailey, that I should prepare a 
paper upon some subject to be chosen by me, I have selected 
Acute Cerebral Inflamations embracing Cerebritis and Menin¬ 
gitis, which I will submit to you for your consideration. 
I do not propose in this to speak much from experience but 
to help to bring the disease before your mind. Acute cerebral 
inflammations are not so commonly met within practice as many
