ABSTRACTS FROM EXCHANGES.

sei ions cases, those of medium seventy, those with mild charac¬ 
ters. And after considering the disease chorea of dog with that 
of man, and, again, the canine disease with infantile paralysis, 
they resume the conclusions as follows: 
1. Canine chorea cannot be compared to that of man. 
2. Human chorea has its anatomical stratum in the cerebral 
cortex and the cerebral ganglions. Chorea of dogs is a meningo- 
encephalo-medullary affection. 
3. The lesions of canine chorea are of inflammatory nature 
and the blood-vessels are primitively affected. The motor ner¬ 
vous cells are altered secondarily. 
4. The lesions of chorea of dog present the greatest analogies 
with those of the infantile paralysis or disease of Heine-meclin, 
and the epidemic form, acute anterior poliomyelitis. 
5. The differences of the symptoms in the two- forms, human 
and animal, viz.: rhythmical tremblings, less marked paralysis in 
the chorea of dog, are probably due to the fact that the spinal 
cord of dog possesses a greater functional independency than 
that of man. 
6. The word chorea is at any rate improper, and the name of 
rhythmical paralysis would be more appropriate according to the 
symptomatic exhibition.— ( Rec. de Med.) 
BELGIAN REVIEW. 
By Prof. A. Liautard, M.D., V.M. 
Surgical Treatment of Sinusitis Accompanied with 
Roaring [Prof. Lienaux]. —This complication of roaring de¬ 
serves attention, as it is not always certain that once the sinuses 
distended towards the median line may, after being in that con¬ 
dition for months, resume their proper dimensions. A new sur¬ 
gical operation that the author has performed in several cases 
may give very satisfactory results. 
In this article the professor passes a minute review of the 
anatomy of the sinuses and of the turbinated bones, and by il¬ 
lustration shows the changes that may occur in the antrum and 
the nasal cavities, when the sinuses or the turbinated or both are 
filled with pus, and, after advising careful attention to the con¬ 
dition of the parts, he arrives at the description of the operation 
which he recommends, consisting not only on the same trephin¬ 
ing of the sinus, but also by resorting to the removal of a long 
portion of the frontal and nasal bones, the uncovering of the dis-
