heretofore I often succeed now by the means here indicated. 
For instance, I have seen the most rebellious, inveterate cases 
of scratches in horses yield readily to an internal treatment 
of arsenic and external application of tarro-petrolene pure 
where I had uselessly given the same treatment internally for 
months, and used locally everything that the veterinary phar- 
macopias in the English and French languages preconized. 
Nor is this all: I found tarro-petrolene superior to any tar 
or other ointment I have yet tried in dryness of the hoof, frog 
and contraction. It also keeps the flies away. I now use 
pounds of this preparation weekly with most encouraging 
success.

CEREBRAL DISEASE IN EQUID^E. 
Louis reports the following: From October i, 1889, to 
January, 1890, six horses belonging to a vine planter became 
sick under symptoms of vertigo and spasms; two of those 
died and four were destroyed. Upon post-mortem, the 
membranes surrounding the cerrebellum, medulla oblongata 
and the spinal cord were found thickened. In the cerebral 
ventricles and spinal canal a bloody exudate to the amount of 
five ounces was secured; otherwise no alterations. 
As soon as the last case became sick, Dr. L. was sum¬ 
moned ; the section in this case was different. Lesions in the 
abdomen awakened suspicions of anthrax ; these were con¬ 
firmed by microscopic examination. 
Another animal afflicted from December 23 to February 
17 manifested symptoms similar to the others at various 
intervals. A very careful examination of the blood of this 
animal, however, gave negative results. 
Eder was unable to obtain satisfactory results by injecting 
pilocarpinum hydrochloricum in sub-acute cerebritis. We 
saw six out of twenty-three recover. The treatment consisted 
of two injections of 0.2 grams antipyrinum with 0.05 physos-
