Pseudo-meningitis Due to a Prevertebral Abscess of 
THE Neck [By Prof Cadeac ].—Very unusual and interesting 
record of an animal which shortly after being bought has 
strangles, complicated with paresia of the facial muscles of both 
sides, more marked on the right than the left. Taken back by 
the dealer he is brought to Prof. Cadeac, when the affection 
makes rapid progress. He refuses food, stands immobile in his 
stall ; constipation is hard, and resists even repeated purgatives. 
The walking is painful; there is paresia of the right lateral 
biped ; there is photophobia, the pupil is contracted, the ears 
are stiff, the masseters also, the membrana nictitans covers the 
eye as soon as the hand is raised toward it. Is it lockjaw ? 
The head can neither be raised nor lowered, the neck is stiff and 
the skin of the region very sensitive ; the animal is very 
rebellious to any examination of the upper part of the neck, 
near the poll. A diagnosis is made of meningitis, nearly all 
the symptoms of which are present. One morning a fistula of 
the superior border of the neck is discovered, discharging very 
freely. The animal is cast ; the tract of the fistula, which is 
deep, irregular and extends to the cervical vertebrae, is cut 
freely; necrosed cervical ligament is removed and a counter 
opening made to allow the pus to escape. The wound is thor¬ 
oughly disinfected and the animal left free. Almost all of a 
sudden all the previous manifestations of the meningitis have 
subsided, and the animal could be considered as cured were it 
not for the wound of the neck. There remains, however, a 
certain deviation of the tip of the nose, which is of old and no 
doubt different nature.— {Jour, of Zootechnie .) 
Chronic Hepatitis [By M. Chauvain ].—This affection is 
imperfectly known in our animals on account of its rarity and 
the difficulty of diagnosis. The author records two cases, the 
diagnosis of the second being made through the manifestations 
shown by the first—manifestations which had been very mild 
and insufficient to call medical attention. The first case was in 
appearance in good general health, and was able to do his work, 
that of a hunter, very well. Nothing on him caused suspicion 
that he had disease of one of his principal organs. One day he 
hunted with possibly less ardor, and was found dead the next 
day in his stall. Minute inquiries about him of his condition 
previous to his dying revealed that, for a month or two before 
he had been less vigorous, did not start galloping so willingly,
